Hi Joe, JointTrack internally uses the networking interface of the local machine for communication between its components. Those errors basically mean those local-machine to local-machines connections could not be established. Did you recently change or install any anti-virus / firewall program? You may need to configure your firewall rules if that's the case.

I assume you mean the OpenCV stuff is complicated, and not JointTrack. If it's the other way around, please let me know :D JointTrack calibration parameters, using the symbols (other than a and V) on the OpenCV documentation page you referenced: principal distance: a * f_x or a * f_y x-offset: a * c_x y-offset: a * c_y pixel size: a position of x-ray source: solution of point M to the equation 0 = [R|t]M' image normal: negative of the 3rd row of the R matrix; in other words, solution of vector V to the equation [0 0 -1]' = R*V image up: 2nd row of the R matrix; in other words, solution of vector V to the equation [0 1 0]' = R*V On the same page you referenced, there is also a cv::calibrationMatrixValues() you can use to get the intrinsic values, where the "aperture" size would be your x-ray detector size (if what you are working on is using x-ray...) JointTrack assumes your images are already distortion corrected, and are isotropic (each pixel has the same dimension in x and y, therefore the principal distance or focal length f_x = f_y).

Hello everyone, I'm trying to convert our calibration data from the OpenCV format <http://docs.opencv.org/2.4/modules/calib3d/doc/camera_calibration_and_3d_reconstruction.html> to the format that JointTrack is able to read for biplane tracking, but it seems complicated to me. Would you help me out with this? Thank you so much.

Download it here! https://sourceforge.net/projects/jointtrack/files/JointTrack/2.3.0%20(API%2C%20experimental%20Python%20plugins)/ Changes: ==================== 2.3.0 (API, experimental Python plugins) -------------------- *User experience:* * % Enhanced: *Faster iterations in the optimization loop if the model display window(s) is minimized (because drawing to the screen and the associated extra computation is skipped). This is most noticable if the models are displayed in edge mode. * %** Fixed:* Image file is not read correctly by the alternative image reader ReaderOpenCV (not used by default) if the image's horizontal resolution is not a multiple of 4 (e.g. 1023x1023 instead of 1024x1024). * * This fix was previously released as a standalone hotfix to ReaderOpenCV.exe. * %** Fixed:* Transparent rendering stops working properly in the main display window after it changes size to display a different sized image. * * The issue affected only the display and not the images generated for the registration algorithm. * %** Fixed:* Rare Ctrl+Shift+Left/Right model manipulation crash, if it is the first-ever model manipulation performed in the main display window when there is a model selected but no prior mouse clicks in the main display area. * %** Adjusted:* Simulated Annealing and Simplex default parameters have been adjusted. Especially, the default translational bound parameter has been adjusted to be more appropriate for most cases where mm rather than inch is used. * * Minor algorithm enhancement on the initial step size used for the first iteration in Simulated Annealing. * %** Adjusted:* Increased maximum allowed resolution of images in the configuration files. * % Enhanced: *The autosave .jts files are automatically deleted upon normal exit by default. Autosave behaviors can be adjusted by modifying the GUIwx.config file. * % Enhanced: *Minor user experience enhancements in the registration parameter configuration dialog. *Features for advaced users:* * % New: * Python plugin support. Python 2.7 (2.7.x only) required. (Binaries for Python 2.6.x can be provided upon request). * * A helper class PluginObjParamsI.py implementing the JTPlugin::PluginObjParams interface is provided for easier creation of new plugins. * % New: * Ability to load an XML Model Specification file that specifies all the STL models used (needed for some experimental algorithms). * * See SampleModelSpecFile.xml in the program's folder for an example. * % New: * Configurable GUI component startup delay before it tries to communicate with JointTrack core and other necessary components. * * Edit GUIwx.config if the GUI consistently fails to start due to other components taking too long to start. *Algorithms:* * % New: * Experimental algorithms, with certain components written in Python (NumPy package required. Some functionality also uses SciPy). * * These are disabled by default. To enable, move/copy appropriate ".cfg" files from the "plugins\disabled" or "plugins_python\disabled" directories into their parent folder, and edit the GUIwx.config file. |

We are glad to announce that JointTrack 2.2.0 is available for download now: https://sourceforge.net/projects/jointtrack/files/JointTrack/2.2.0%20(algorithm,%20feature)/ Changes: ==================== 2.2.0 (algorithm, feature) -------------------- *Algorithms:* * %** New: * KneeTrack method (enhanced). * % New: * Simplex opimizer + Mahfouz metric. * % Enhance: * Mahfouz metric: User can now change the weights placed upon the intensity score and edge score, as well as choose whether to use smoothing on the edge images. * * *To switch between different registration algorithms, comment out / uncomment relevant lines in GUIwx.config which is a plain text file. After you've decided which one is best for you, you can prevent irrelavant plugins from running by altering the file name extension for appropriate ".cfg" files in the "plugins" folder. *Others:* * % Added: * Capability to save screenshots (in File menu). * % Added: * Capability to remove a model (in right mouse button context menu). * % Added:* Auto backup of kinematics on changing current frame. * % Fixed:* User is now asked for confirmation when overwriting an existing kinematics file. * % Added: * In keyboard control, added rotation about model's z-axis. Originally there was only z-rotation about the z of the x-ray system coordinates. Tweaked some other keyboard controls. * % Tweak:* Rearranged load/save kinematics buttons. User can opt to use an enhanced version of the old layout by renaming files in the "rc" directory. * % Added: * Capability to load external calibration parameters. (A user can now work in his own cooridnate system.) * % Fixed: * Improper display of x-ray images in original size after displaying images downsampled. |

Amir, Please refer to ChangeLog.txt for changes. The transparent rendering feature in the new version (2.1.3) can improve accuracy for natural bone measurements. Accuracy really depends on your image quality, image size, shape of the model, and other factors. Please refer to literatures for numbers, where RMS errors are typically ~0.5-1mm for in-plane translations and ~0.5degree for rotations. Example literature: 1. Moro-oka T, Hamai S, Miura H, et al. 2007. Can magnetic resonance imaging-derived bone models be used for accurate motion measurement with single-plane three-dimensional shape registration? J Orthop Res 25: 867-872. 2. Fregly BJ, Rahman HA, Banks SA. 2005. Theoretical accuracy of model-based shape matching for measuring natural knee kinematics with single-plane fluoroscopy. J Biomech Eng 127: 692-699.

JointTrack 2.1.2 fixed a potential deadlock introduced in the last version. Please download the new version if you installed v2.1.1. http://sourceforge.net/project/showfiles.php?group_id=167273&package_id=190235&release_id=619056 Change log: ==================== 2.1.2 (hotfix) -------------------- % Fixed: The program may freeze when switching images / loading models. This bug was due to a potential deadlock introduced in last version's plotting code. (JTRendererVTK) |

JointTrack 2.1.1 is released. Check out the plots! http://sourceforge.net/project/showfiles.php?group_id=167273&package_id=190235&release_id=618040 Change log: ==================== 2.1.1 (feature, bug fix) -------------------- % Added: Side graphs/plots to facilitate registration. (JTRendererVTK, core) % Fixed: Primary model display window: keyboard interaction crashes the program if the user has never had mouse interaction in the window. (JTRendererVTK) % Fixed: Rotation center of keyboard z-rotation interaction was supposed to be changed to model's origin in last version. (JTRendererVTK) % Fixed: (fixed again) mouse wheel may cause the model or view to move dramatically. This bug was reintroduced in the last version due to the bugged wxVTKRenderWindowInteractor.

We are glad to announce the release of JointTrack 2.1.0: http://sourceforge.net/project/showfiles.php?group_id=167273&package_id=190235&release_id=610096 Change log: ==================== 2.1.0 (feature, API, bug fix) -------------------- User experience: % Changed: New jts file format. See the last section for more information. (core) % Added: Utility: jtsconvert.exe to convert kinematics (.jts) file between different pose representations or convert old format .jts file to the new format. % Changed: Instead of having to click exactly on the model to move it, user interaction now acts on the current model. Be careful though: you may accidently rotate a model when you are just trying to bring the window to foreground. (JTRendererVTK) % Changed: All rotations are now about the model's origin(not center). (JTRendererVTK) % Changed: Changed how the program calculates rotation for left mouse button interaction (without pressing ctrl key). (JTRendererVTK) % Changed: Some default values (rotation search bounds and termination tolerance) in the 'config registration' dialog. (OptiSimAnneal_Ice) % Added: "Optimize whole sequence" button. (GUIwx) % Added: "Save all kinematics" and "Load all kinematics" buttons. (core, GUIwx) % Added: User now gets a warning if the jts file being loaded contains more data than needed. (core) % Fixed: Unchecking checkbox "image is black (bones) on white (background)" did not take immediate effect if the user has already run the optimization once with that checkbox checked. The bug remained in effect until the user switched to a different image. (CostFuncSFMahfouz) % Fixed: During optimization the program may crash or hang if the user tries to interact with the model display windows. (JTRendererVTK) % Fixed: "Reset" button for the canny edge parameters no longer causes error. (GUIwx) % Fixed: No more problems at image loading when the user has invalid intensity/canny parameters in the UI controls. (GUIwx) % Fixed: Pressing Q or E in the secondary model display window caused it to close. (JTRendererVTK) % Fixed: User can no longer close the model display windows. User can no longer resize the main model display window. (JTRendererVTK) % Fixed: Model may become half clipped in the secondary model display window when user manipulates the model using keyboard. (JTRendererVTK) % Fixed: The secondary model display window initially may show up behind the main model display window. This no longer happens unless the main model display window is very big. (JTRendererVTK) % Fixed: A singularity value (in the sense of Euler angles) may cause JointTrack to generate jts files with invalid values. (This was due to compiler optimization error, so it wouldn't happen in debug build.) (core) % Removed: Removed non-functioning buttons. (GUIwx) Major API changes: % Added one inheritance level to plugin hierarchy so that non-image-based registration routine can be added later. % Data order in Pose.rotation vector is now required to conform to the actual Euler sequence (if Euler angle is being used). Kinematics(.jts) file format change note: JointTrack still can load old format kinematics files. In addition to saving kinematics to new format files in JointTrack, user can also use command-line tool jtsconvert.exe to convert old format files to the new format. In old jts files, the six columns were "x_tran, y_tran, z_tran, x_rot, y_rot, z_rot". In order to represent symmetric Euler sequences (for example, 3-1-3), column orders have been changed to conform to the actual Euler sequence. New format jts files have column headers. |

Dear JointTrack users, A bug that could affect the accuracy of the registration result was discovered in JointTrack. Symptom: The checkbox "image is black (bones) on white (background)" does not always immediately take effect. The bug only occurs when your image is actually white on black, and you have already run the optimization once with that checkbox checked. Workaround: If you have multiple images loaded, switching to a different image and then switching back will force the checkbox to take effect. Fix: The fix will be included in the next release. The bug is in the "CostFuncSFMahfouz" plugin. Shang |
