use bwconncomp for large sparse matrices
3 ビュー (過去 30 日間)
I have 3d image (a stack of 1600 images), I had to save the info in two 1800*1800*800 matrices (because of memory), both matrices are sparse matrices (density~0.02) _ is there anyway to use bwconncomp in 3d for the 3d image (combination of matrices)? if not whats the best way to identify the objects and characterize them?

I think the example in the documentation may be what you are looking for. Please, find the "Calculate Centroids of 3-D Objects" example among the ones proposed here:
Is this what you want? For more properties, try also the "regionprops" function, look at its "Properties". As you can see, some properties work with N-D matrices:
