We are about to switch to a new forum software. Until then we have removed the registration on this forum.
For an installation, I use a kinect V2 to obtain a deep map of a space. I need to calculate some blob centroid from that deep map. I try with BlobDetection, blobscanner or openCV libraries and it was very slow, not usable. At the moment the best solution is to send 2 preprocessed depth image to Isadora via Syphon, use 2 Eyes++ actors in Isadora (blob detector actors) and send the result via OSC to processing to finally use fragment shader to process the final image.
It's complicated but it works at 30 f/s in processing and Isadora with very acceptable lag.
I search a way to do the blob decoding in GLSL shader via processing.
Is any one with an idea how to do that?
Thank you in advance. Jacques
