graymorph1_reg.c File Reference

(1) Tests the interpreter for grayscale morphology, as given in morphseq.c. (2) Tests composite operations: tophat and hdome. (3) Tests duality for grayscale erode/dilate, open/close, and black/white tophat. (4) Demonstrates closing plus white tophat. Note that this combination of operations can be quite useful. (5) Demonstrates a method of doing contrast enhancement by taking 3 * pixs and subtracting from this the closing and opening of pixs. (6) Playing around: extract the feynman diagrams from the stamp, using the tophat. More...
