I need to count + get positions and sizes of stars in a big sky photography like this one :

all cv.jit.blobs.* object work only with the output of cv.jit.label @charmode 1

Even with @charmode 0, the output of cv.jit.label is a type long matrix, which is limited to 2024, and that’s probably not enough for my needs…

If I split my large image file into smaller pieces, I’ll certainly have some blobs/stars counted twice or ignored if they are on the edge of a slice…

Is there a way to overcome this char limitation ?

or perform a basic blob detection in gen ?

I’ve found this Python lib that seems to do the job perfectly :

but I’ve no idea on how to do this in Max (/ communicate with a Python script, …)

that mean we are limited to 255 blobs

cv.jit.label / blobs : how to track more than 255 blobs ? (count stars in sky)
