Image segmentation involves converting an image into a collection of regions of pixels that are represented by a mask or a labeled image. By dividing an image into segments, you can process only the important segments of the image instead of processing the entire image. A common technique is to look for abrupt discontinuities in pixel values ...

Note the curly braces. If you used regular MATLAB indexing, like so: det1 = det(A(1)) %% DOESN'T WORK you would get an error, because det() doesn't work on cell arrays. The dereferencing curly braces are needed to remove the outer layer (the cell array) and get at the inner layer (the matrix). To divide by a number, you just do normal division: Reshape a matrix by splitting it after k columns in MATLAB.
