The AXIOM Beta features a small programm called cmv_hist3 that calculated raw histogram values (https://en.wikipedia.org/wiki/Image_histogram) from a current image in the real time processing pipelien. 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 cource code: https://github.com/apertus-open-source-cinema/beta-software/tree/master/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 Vectorscopes (https://en.wikipedia.org/wiki/Vectorscope) display as typically used with cinematography/color analysis.
