Load 3-D MRI data, remove any singleton dimensions, and convert the data into a grayscale intensity image. … WebHere N is the number of pixels in the input image and K is the number of superpixels. This value is used to define a grid with regW × regH superpixels. The initialisation code determines an initial location (p x, p y) for each superpixel by using constant distance increments.As such, initial regions define a regular grid.

WebCompact Superpixels (CS) and Constant-Intensity Superpixels (CIS) are two approaches that formulate the superpixel segmentation problem in energy optimization. CS assumes that the input image is intensively covered by half-overlapping square patches of the same size, thus it shows uniform compactness with regular shape and size. CIS assigns ...
