Image::Leptonica::Func::fmorphgen1
VERSION
version 0.03
fmorphgen.1.c
Top-level fast binary morphology with auto-generated sels
PIX *pixMorphDwa_1()
PIX *pixFMorphopGen_1()
FUNCTIONS
pixFMorphopGen_1
PIX * pixFMorphopGen_1 ( PIX *pixd, PIX *pixs, l_int32 operation, char *selname )
pixFMorphopGen_1()
Input: pixd (usual 3 choices: null, == pixs, != pixs)
pixs (1 bpp)
operation (L_MORPH_DILATE, L_MORPH_ERODE,
L_MORPH_OPEN, L_MORPH_CLOSE)
sel name
Return: pixd
Notes:
(1) This is a dwa operation, and the Sels must be limited in
size to not more than 31 pixels about the origin.
(2) A border of appropriate size (32 pixels, or 64 pixels
for safe closing with asymmetric b.c.) must be added before
this function is called.
(3) This handles all required setting of the border pixels
before erosion and dilation.
(4) The closing operation is safe; no pixels can be removed
near the boundary.
pixMorphDwa_1
PIX * pixMorphDwa_1 ( PIX *pixd, PIX *pixs, l_int32 operation, char *selname )
pixMorphDwa_1()
Input: pixd (usual 3 choices: null, == pixs, != pixs)
pixs (1 bpp)
operation (L_MORPH_DILATE, L_MORPH_ERODE,
L_MORPH_OPEN, L_MORPH_CLOSE)
sel name
Return: pixd
Notes:
(1) This simply adds a border, calls the appropriate
pixFMorphopGen_*(), and removes the border.
See the notes for that function.
(2) The size of the border depends on the operation
and the boundary conditions.
