V2.0.2 (July 27/Sep 2, 2015)

Functions related to our award-winning (1st place) approach for foreground-/ background-separation and leaf counting, as described in our presentation and publication in connection with the CVPPP 2014 workshop in Zurich:

• A new analysis block to count the number of different colors in the VIS images has been added (BlCountColors).
• Detect leaf center points block: calculates a eucledian distance map and detects peaks in that image. As a result center points in convex areas are detected (e.g. leaves of rosette plants) (BlDetectLeafCenterPoints).
• Label leaf areas using advanced graph-based leaf area split line calculations. Only IAP incorporates an advanced graph library (VANTED) utilizing graph visualisation and manipulation commands (BlDetectLeafCenterPoints).

Further additions and bug fixes:

• The calculation of the convex hull length was incorrect. This problem has been resolved. Previous calculations of the convex hull length and of the convex hull compactness are either incorrect (in about 10% of the cases) or missing in the result table row (in about 90% of the cases). Other values, such as convex hull area are not affected by this bug.
• For testing purposes a image resize block was added.
• Datasets can be created from a list of files using the 'Load or Create Dataset'

  'Create Dataset from Files' commands.

V2.0.0 (March 17, 2015)

• Culmination of a larger number of improvements, both on usability as on feature completeness.
• Uses a different settings folder path (postfix '2.0') in order to separate settings and stored pipelines from previous versions (1.x), as analysis block names and parameter names changed from version 1.1.x to 2.x.
• The program documentation (documentation.pdf) may still reflect in part old settings names and analysis block names. In case of difficulty, it is recommended to download and use IAP version 1.1.x, as described in the documentation.pdf from November 2013 (see bottom of title page). Once you are proficient in working with the system, you may update and use version 2.x, which adds new features and is more streamlined. A revision of the documentation will be created over time.
• After a long period of working at IPK, developing VANTED, KGML-ED and IAP, time has come to finish the current chapter. The overall functionality of these systems is mostly preserved within IAP.

Upgrade procedure

1. Unzip the downloaded iap.zip file and use the startup-scripts to start IAP. Modify the memory settings (-Xmx7g) within the windows or linux/mac start- script to fit your system configuration (e.g. system memory minus one or two gigabytes). For Mac/Linux, use the ".sh" script files for starting. For Windows, use the ".cmd" script files for starting the program.

2. Confirm the proper update, by clicking "About". The first text box should include the text "(V1.0.3)" or a higher number, depending of the intended download version, below the program name.

New installation

Perform step 1 of the upgrade procedure documentation.

In case of problems/errors:

Within IAP click "Settings > Show Config-File". Close IAP. Move one directory up and delete or rename the IAP settings folder (starting with "IAP" or ".iap").
