void AddLargeSpeckleTo ( BLOB_CHOICE_LIST * Choices )

This routine adds a null choice to Choices with a rating equal to the worst rating in Choices plus a pad. The certainty of the new choice is the same as the certainty of the worst choice in Choices. The new choice is added to the end of Choices.

Globals:

speckle_small_penalty rating for a small speckle
speckle_large_penalty rating penalty for a large speckle
speckle_small_certainty certainty for a small speckle

Parameters:

Choices choices to add a speckle choice to

Returns:: New Choices list with null choice added to end.

BOOL8 LargeSpeckle ( TBLOB * blob )

This routine returns TRUE if both the width of height of Blob are less than the MaxLargeSpeckleSize.

Globals:

speckle_large_max_size largest allowed speckle

Exceptions: none History: Mon Mar 11 10:06:49 1991, DSJ, Created.

Parameters:

blob	blob to test against speckle criteria

Returns:: TRUE if blob is speckle, FALSE otherwise.
