The code snippet above is using the parallel computing feature of MATLAB, specifically the "parfor" loop, to apply the Sobel edge detection algorithm on each channel of a layered image.
The input image is represented by the variable "Y" and the number of channels or layers is stored in "layer.numChannels".
Within the loop, the edge function is applied to each channel using the Sobel filter, which calculates the gradient of the image intensity values in the x and y directions. The resulting edge map is stored in the variable "Z" for each channel.
By using "parfor", MATLAB will automatically distribute the loop iterations across multiple processing cores, potentially reducing the execution time compared to a regular "for" loop.
