ConnectedComponentsImage

ConnectedComponentsImage() returns the connected-components of the image uniquely labeled. The returned connected components image colors member defines the number of unique objects. Choose from 4 or 8-way connectivity.

You are responsible for freeing the connected components objects resources with this statement;

objects = (CCObjectInfo *) RelinquishMagickMemory(objects);

The format of the ConnectedComponentsImage method is:

Image *ConnectedComponentsImage(const Image *image,
  const size_t connectivity,CCObjectInfo **objects,
  ExceptionInfo *exception)

A description of each parameter follows:

image
the image.
connectivity
how many neighbors to visit, choose from 4 or 8.
objects
return the attributes of each unique object.
exception
return any errors or warnings in this structure.

IntegralImage

IntegralImage() returns the sum of values (pixel values) in the image.

The format of the IntegralImage method is:

Image *IntegralImage(const Image *image,ExceptionInfo *exception)

A description of each parameter follows:

image
the image.
exception
return any errors or warnings in this structure.
