Hi all,
I have data uint16 .mat. then I label it into tumor and background, and save it into logical .mat. Means the background is 0, tumor is 1.

uint8() the logical mask and multiply by the uint8 data. The locations where the mask is false will come out 0.

this one is for total no. of voxel.
Voxels = sum(logical(:)==1)
then how to extract the PixelIdxList?
