femtoCAM

This tool records video from Genicam cameras (via https://github.com/AravisProject/aravis), finds peaks in real time multithreaded and exports the data (TODO).

This is a complete re-write of a private code base.

Output files (TODO):

• info_[n].txt (outputfile): info text file
• hitlist_[n].dat (hitlistData): binary file
• extended_[n].dat (wf): binary file

hitlist

contains information about how many hits were found on a specific pixel. For each pixel where a hit was found 6 bytes are added to the file in the format: [<uint16_t> i, <uint16_t> j, <uint16_t> counts] - TODO: find out if i,j is x,y or y,x

extended

contains all info about time resolved hits

• 12 byte header: [<uint32_t> dataRows, <uint32_t> numDataPoints, <uint32_t> processedFrames]
• processedFrames * 4 bytes: [<uint32_t> * processedFrames], each corrospoding to the value of hits per frame
• dataRows * numDatapoints * 2 bytes: [[<uint16_t> * numDatapoints] * dataRows] => numDatapoints = 4: [cx, cy, carea, (int)(roundness * 1000.0)]
