HitMissTransform

HitMissTransform[image, ker] gives the hit-or-miss transform of image with respect to the composite structuring element ker.

• HitMissTransform[image, {ker1, ker2, ...}] gives the union of the hit-or-miss transforms for all the structuring elements keri.
• HitMissTransform[image, {ker1, ker2, ...}, t] treats values above t as foreground.

Examples

Detect corners:

img = Binarize[ExampleData[{"TestImage", "Shapes"}]];
ker = {{0, 1, -1}, {1, 1, -1}, {-1, -1, -1}};
HitMissTransform[img, ker]

Multiple kernels:

HitMissTransform[img, {ker1, ker2, ker3}]
