Applications without matching coding challenge completed will not be considered.
The AXIOM Beta features a small program called cmv_hist3 that calculated raw histogram values (https://en.wikipedia.org/wiki/Image_histogram) from a current image in the real time processing pipeline. cmv_hist3 is not meant to be fully real time capable as it is enough in most cases to calculate a new histogram with every couple of frames captured (image sensor can also run up to 300 fps).
cmv_hist3 source code: https://github.com/apertus-open-source-cinema/beta-software/tree/master/software/cmv_tools/cmv_hist3
First steps are understanding and improving this tool with small new features (crop image and extract histogram only from selection), etc.
The next steps are creating similar tools for Waveform (https://en.wikipedia.org/wiki/Waveform_monitor) and Vectorscope (https://en.wikipedia.org/wiki/Vectorscope) display as typically used with cinematography/color analysis.
A good introduction to these tools can be found here:
While these tools can be fully CPU-based, using subsampling to achieve a decent frame rate, it's best to accelerate them using FPGA. Of course, this will increase the task difficulty and is therefore optional.
- Basic math knowledge
- optional: VHDL
