Routines

Runs a convolution filter on a gray image and put the result on to an output gray image object. A mask object must be specified as an input parameter. The mask file is a text file on disk and has a specific mask structure. Once loaded, it is handled as a GrayImage object and is further used only by the themedian filtering algorithm implementation.

required external library: image

void ConvolImage ( GrayImage in, GrayImage out, GrayImage mask );

Parameters

in	[in] GrayImage variable that handles the gray scale input image
out	[out] GrayImage variable that handles the gray scale output/result image
mask	[in] GrayImage variable that handles the grayscale mask

Return values

The routine does not return anything.

Example code

loadlib image;

GrayImage in,out,mask;

main()

{

LoadGrayImage(in,"anger.bmp");

LoadMask(mask,"m1.mask");

ConvolImage(in,out,mask);

}
