L_TissueEqualizeBitmap

#include "l_bitmap.h"

L_LTIMGCOR_API L_INT EXT_FUNCTION L_TissueEqualizeBitmap(pBitmap, uFlags)

pBITMAPHANDLE pBitmap;	pointer to the bitmap
L_UINT uFlags;	flags

Performs equalization between the hard tissue and the soft tissue in X-ray images, resulting in better quality for better interpretation and understanding of the image.

Parameter	Description
pBitmap	Pointer to the bitmap handle referencing the bitmap to perform the equalization operation on.
uFlags	Flags that indicate the type of processing. Possible values are:
	Value	Meaning
	TISSUEEQUALIZE_INTENSIFY	[0x00000002] Performs tissue equalization with contrast intensification.
	TISSUEEQUALIZE_SIMPLIFY	[0x00000001] Performs tissue equalization with simplification of intensity values across the image.

Returns

SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

If the bitmap has a region, the effect will be applied on the region only; otherwise the whole image will be processed.

This function supports DICOM images.

This function does not support 32-bit grayscale images. It returns the error code ERROR_GRAY32_UNSUPPORTED if a 32-bit grayscale image is passed to this function.

Example

This example loads a bitmap and applies the Tissue Equalization on it

#define MAKE_IMAGE_PATH(pFileName) TEXT("C:\\Users\\Public\\Documents\\LEADTOOLS Images\\")pFileName 
L_INT TissueEqualizeExample(L_VOID) 
{ 
   L_INT nRet; 
   BITMAPHANDLE LeadBitmap; /*Bitmap handle to hold the loaded image*/ 
   /* Load the bitmap, keeping the bits per pixel of the file */ 
   nRet = L_LoadBitmap (MAKE_IMAGE_PATH(TEXT("ImageProcessingDemo\\Image3.cmp")), 
   &LeadBitmap, sizeof(BITMAPHANDLE), 0, 
   ORDER_BGR, NULL, NULL); 
   if(nRet != SUCCESS) 
      return nRet; 
   //Apply Tissue Equalize filter with Intensify option 
   nRet = L_TissueEqualizeBitmap(&LeadBitmap, TISSUEEQUALIZE_INTENSIFY); 
   if(nRet != SUCCESS) 
      return nRet; 
   //free bitmap 
   if(LeadBitmap.Flags.Allocated) 
      L_FreeBitmap(&LeadBitmap); 
   return SUCCESS; 
}
