Detailed Description

Image segment (consecutive region of pixels satisfying some value constraint) The list of pixels in this segment are stored as a list of ImPixel objects. Basic geometric properties of the segment can be computed. TODO: beef up the segmentation map to contain all info necessary to go back to the object/fibers and measure more properties.
