SIP stands for Scilab Image Processing toolbox. SIP intends to do imaging tasks such as filtering, blurring, edge detection, thresholding, histogram manipulation, segmentation, mathematical morphology, color image processing, etc.

These operations are useful for problem solving in real-world applications ranging from car motion planning to automatic diagnosis of medical images.

SIP is meant to be a complete, useful, and FREE digital image processing toolbox for Scilab.
