L_TissueEqualizeBitmap

Summary

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.

Syntax

#include "l_bitmap.h"

L_LTIMGCOR_API L_INT EXT_FUNCTION L_TissueEqualizeBitmap(pBitmap, uFlags)

Parameters

pBITMAPHANDLE pBitmap

Pointer to the bitmap handle referencing the bitmap to perform the equalization operation on.

L_UINT 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

Value	Meaning
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

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; 
}
