MMACH (lmmach) functions


LIBRARY ROUTINE

lvchghomot - Change the homotopy of an image.

LIBRARY CALL

int
lvhomot(xvimage *img1, xvimage *img2, mat_str *b, xvimage *img3, int mflg, xvimage *img4)

INPUT

none

OUTPUT

none

RETURN VALUE

TRUE (1) on success, FALSE (0) on failure

DESCRIPTION

vhomot will change the homotopy of an image, based on a reference image. img1 is the input images; img2 is the reference image; b is a structuring element; img3 is the gating image; mflg is a flag. mflg should be set to 1 if the gating image is to be used. A non-zero mask pixel in img2 enables the output pixel to contain the result. A zero mask pixel in img2 just transfers the value of the corresponding pixel in img1 to the output pixel.

The input images and the optional mask image must be of the same size, data type and have the same number of data bands. The image img2 is also used to return the result.

ADDITIONAL INFORMATION

none

EXAMPLES

SIDE EFFECTS

none

RESTRICTIONS

lvhomot can be defined for all data types supported by Khoros (except bit), but at the moment it has been implemented just for the unsigned char types.

MODIFICATION

Adriano Nagelschmidt Rodrigues: port to new toolbox version.
