HitMissTransform

HitMissTransform[image, ker]
gives the hit-and-miss transform of image with respect to the composite structuring element ker.
HitMissTransform[image, {ker1, ker2, ...}]
gives the union of the hit-and-miss transforms for all the structuring elements keri.
HitMissTransform[image, {ker1, ker2, ...}, t]
treats values above t as foreground.
  • The composite structuring element ker is a matrix containing 0, +1 and -1 elements, with +1 elements representing foreground and -1 elements representing background.
  • HitMissTransform automatically adds zeros to structuring elements so that they have odd dimensions.
