PIX * | pixColorMorph (PIX *pixs, l_int32 type, l_int32 hsize, l_int32 vsize) |
Top-level color morphological operations PIX *pixColorMorph() Method: Algorithm by van Herk and Gil and Werman, 1992 Apply grayscale morphological operations separately to each component.
Definition in file colormorph.c.
[in] | pixs | |
[in] | type | L_MORPH_DILATE, L_MORPH_ERODE, L_MORPH_OPEN, or L_MORPH_CLOSE |
[in] | hsize | width of Sel; must be odd; origin implicitly in center |
[in] | vsize | ditto for height of Sel |
Notes: (1) This does the morph operation on each component separately, and recombines the result. (2) Sel is a brick with all elements being hits. (3) If hsize = vsize = 1, just returns a copy.
