Masking

Masking
is an option for various image analysis and processing functions that specifies on which regions they should operate.
  • With Masking->image, the region of interest corresponds to positive pixels in image.
  • Masking->array operates on regions corresponding to positive values in array.
  • When the region of interest is specified as an array or image, it is taken to be centered on the image to be processed.
  • Masking->graphics rasterizes arbitrary graphics to the size of the image to be processed, and operates on regions that correspond to positive values in the raster.
