L_AutoBinaryBitmap
#include "l_bitmap.h"
L_INT EXT_FUNCTION L_AutoBinaryBitmap(pBitmap)
|
pBITMAPHANDLE pBitmap; |
/* pointer to the bitmap handle */ |
Applies binary segmentation to the bitmap using an automatically calculated threshold based on a two-peak method of statistical analysis of the histogram. This function is available in the Document/Medical Toolkits.
|
Parameter |
Description |
|
pBitmap |
Pointer to the bitmap handle referencing the bitmap to segment. |
Returns
|
SUCCESS |
The function was successful. |
|
< 1 |
An error occurred. Refer to Return Codes. |
Comments
The bitmap is transformed into a binary image using a threshold calculated automatically based on statistical features of the bitmap. Best results are obtained with grayscale bitmaps.
If the bitmap has a region, the effect will be applied on the region only.
This function supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
This function does not support signed data images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image is passed to this function.
