Morphological Filters

Morphological filters change the shape of objects contained within an image. These filters are widely used before applying character and shape recognition algorithms because these filters can highlight the contour of the objects. Morphological filters can be applied to monochrome (binary) and grayscale images.

Black Ice imaging tools currently support the following morphological filters:

Closing (binary)	ActiveX	SDK
Closing (grayscale)	ActiveX	SDK
Dilation (binary)	ActiveX	SDK
Dilation (grayscale)	ActiveX	SDK
Erosion (binary)	ActiveX	SDK
Erosion (grayscale)	ActiveX	SDK
HitMiss (binary)	ActiveX	SDK
Opening (binary)	ActiveX	SDK
Opening (grayscale)	ActiveX	SDK
Outlining (binary)	ActiveX	SDK
Skeleton (binary)	ActiveX	SDK
Thickening (binary)	ActiveX	SDK
Thinning (binary)	ActiveX	SDK
TopHat (grayscale)	ActiveX	SDK
