Testing images for scientific purposes
The TESTIMAGES archive is a huge and free collection of sample images designed for analysis and quality assessment of different kinds of displays and image processing techniques. The archive includes more than 2 million images originally acquired and divided in three different categories: SAMPLING and SAMPLING_PATTERNS (aimed at testing resampling algorithms), COLOR (aimed at testing color rendering on different displays) and PATTERNS (aimed at testing the rendering of standard geometrical patterns). Please cite the following papers when using any image in this archive: * ASUNI N, GIACHETTI A, "TESTIMAGES: A Large Data Archive For Display and Algorithm Testing", Journal of Graphics Tools, Volume 17, Issue 4, 2015, pages 113-125, DOI:10.1080/2165347X.2015.1024298 * ASUNI N, GIACHETTI A, "TESTIMAGES: a large-scale archive for testing visual devices and basic image processing algorithms", STAG - Smart Tools & Apps for Graphics Conference, 2014.
CSV Comparator is a tool for comparing files which contain CSV-Data.
CSV Comparator is a tool for comparing files which contain CSV-Data. It was created for performance engineers to be able to have a easy way to compare data from two testruns and be able to automate the comparing process of various files with scripts. There is a command line tool as well as a user interface. In case you need to compare .xml-Files you can convert them to .csv-Files with my other project CSV Transformer. The advantages by using CSV as input and output are the following: - Many applications allow an export of its data to CSV or Excel(were it could be saved to CSV) - It is possible to pre- and postprocess the data, e.g removing version numbers before comparing - It is easy to create CSV data from logfiles and other resources by using unix tools like sed or awk - CSV can be loaded into other applications, especially Excel, were it can be formatted by macros for analyzing.
Serial Bootloader for Microchip, Atmel, NXP, TI, 8051 microcontrolers
What is it? It's a Bootloader for Microchip, Atmel, NXP, TI and 8051 devices. A Bootloader is a firmware running in the microcontroler device which allows the user to send it's own firmware without the need of a programmer. This Bootloader consists of: - firmwares for many devices (this firmware need to be send to the device's flash memory with a programmer, only once) - a PC software which communicates with the bootloader firmware in the device and send the user's program in its memory Where does it come from? This Bootloader is based on "Tiny PIC Bootloader" made by Claudiu Chiculita. A special THANK to him!!! What can it do? It can program: - Microchip PIC10/12/16/18/24/32/dsPIC30/33 - Atmel ATtiny, ATmega - TI MPS430 - NXP ARM Cortex-M0+ - Silicon Labs C8051 And this: - with light modifications to the Bootloader firmware for new devices - without modifying your source code or using a special linker script - via GUI or command line prog - with automatic Reset
Microcontroller based PC Oscilloscope
PPMScope is a do-it-yourself oscilloscope with an open source design. The intent is that the project can be constructed by an electronics hobbiest using the instructions included. The design is a compromise between features and cost. The bandwidth is lower than a commercial scope, so it's use is limited to signals of 500 kHz and below. It's sample buffer is also smaller than a commercial scope, however sufficient for most oscilloscope functions. This is a version based on the PIC16F877A microcontroller running with a 20MHz clock. The maximum sampling rate is 1 MHz with a 5 Mhz equivalent sampling mode. Currently, the computer interface supports USB, serial, and parallel ports. Good luck on the construction and I hope you enjoy your oscilloscope. I am happy to answer any questions or provide technical support for this design.
ReViMS, a 3D volume rendering tool for light-sheet/confocal microscopy
Reconstruction and Visualization from Multiple Sections (ReViMS), an open-source, user-friendly software for automatically estimating the volume of 3D multicellular aggregates (i.e., cancer spheroid, zebrafish, fruit fly). ReViMS requires a z-stack of 2D binary masks, obtained by segmenting a sequence of fluorescent images acquired by scanning the aggregate along the z axis, using a confocal or a light-sheet fluorescent microscope. It provides a number of tools for: (a) segmenting z-stacks of fluorescence images; (b) reconstructing the 3D surface of the aggregates and estimating their volume. ReViMS is written in MATLAB (The MathWorks, Inc., Massachusetts, USA). It is an open-source tool and the source code is freely available at: http://sourceforge.net/p/revims Requirements: MATLAB 2015a and Image Processing Toolbox 9.2 or later versions.
Card generator for the russian L1-3/L3-3 tube tester.
KNOWN BUG: G1 on cap doesn't really work since the G1 plug is connected to internal line I. I have to find a way to connect this automatically while checking that line I isn't used already. DON'T USE THAT FEATURE YET. Creates test cards for the L1-3/L3-3 after entering the pinout, test operating point, and nominal values for currents and transconductance. Fixed the missing heating voltage for low-power battery valves and the stuck connections when loading *.tds files after editing a tube with more pins. WARNING: The software is in extreme alpha state, so bugs are not only possible, they are definitely existing in huge quantities. If you want to use the created cards for real tests, check them manually with EXTREME care first .. else destruction of your tester can easily occur. ESPECIALLY check if multiple functions are assigned to the same line (by looking on the universal card), which would lead to shorts. NEW UPDATE: Started to work on the remake again!
ACARS decoder for GNURadio, tested on RTL2832U based receivers.
A "simple" demonstration software for decoding ACARS, a low-bandwidth communication protocol used by airplanes to communicate with airports. Detailed description of the operating principles is available at http://jmfriedt.free.fr/lm_sdr.pdf (French) and http://jmfriedt.free.fr/en_sdr.pdf (English).
