Hi !! I try to make computer vision library working in processing work under android with ketaicamera. Things don’t seem so simple and results are not as expected (quit……). So I would like to have some precision about the algorithm of ketaicamera decompression compared to the processing Capture algorithm- I hope that understanding differences between them would help me to debug blob detection under android. Thanks in advance ! and congratulations for your work and book !

Hi Fanny, a word of caution. The recursive algorithms in (Open) CV libraries exceeds the stack available on the Android. We’ve looked into this and were successful for very few blobs/objects, but saw it as a dead-end if many blobs/objects need to be detected. Essentially, the stack is the difference. Best, Daniel

It does make sens !! thanks a lot for the reply. I will try to make a thread runnable for blob detection. Apparently, it’s possible to change the stack size with this process. Merci
