HANDLE CALLBACK BinarySkeleton( HDIB hDIB,
int MaxStep,
BOOL BackGrndisBlack,
int iShowProgress,
HWND hParent)
Description
This function will morphologically skeletonize the binary image. The function works for only 1 bit per pixel images. The binary skeletonization of an object defines a unique compressed geometrical representation of the object. Skeletonization is often referred to as the Medial Axis Transform. Morphological skeleton is processed by binary thinning operation several times iteratively until no further changes occur.
Examples
The original 43 x 39 pixel object and the image of the skeletonized object.
Parameters
HDIB |
hDIB |
Handle of the DIB to filter. |
Int |
MaxStep |
This parameter specifies the maximum number of thinning operations. If MaxStep is 0, binary skeletonizing will be processed iteratively until no further changes occur. |
BOOL |
BackGrndisBlack |
This parameter specifies the color of the object and background. |
int |
iShowProgress |
This parameter specifies the displaying of the progressbar and the preview dialog. Available values: DISPLAY_NONE (0) - The progressbar and the preview dialog will not display before filtering. DISPLAY_PROGRESS (1) -The progressbar will display during filtering procedure. DISPLAY_DIALOG (2) - The preview dialog will display before filtering. This dialog shows the part of the image before and after filtering. DISPLAY_BOTH (3) - The progressbar and the preview dialog will display. IMPORTANT: The preview dialog will only display, if there is BiDlgs.dll installed. |
HWND |
hParent |
Handler of the parent window. |
Return values
The handle of the new filtered DIB or NULL if an error occurred.
Programming notes
The function will not free the input DIB.
