L_INT LBitmap::AutoSegment(prcRect, uFlags = 0)
Performs automated segmentation of a rectangular area in the class object's bitmap. The result is applied to the image as a region.
Pointer to Windows RECT structure that specifies the part of the bitmap to perform the segmentation on.
Reserved for future use. Must be 0.
|SUCCESS||The function was successful.|
|< 1||An error occurred. Refer to Return Codes.|
This function was designed specifically for CT/MRI images, to segment regions of cancer clusters.
It is preferred that prcRect points to a rectangle that includes all needed object to be selected. Failure to do so will result in a partial selection of the object as the function will only segment inside the desired rectangle.
Try to make an informed selection, i.e. do not select more than the object you need to isolate and segment.
The rectangle must not exceed the borders of the image; otherwise the function will return an ERROR_INVALID_PARAMETER error and will not execute.
When the resultant region is no longer needed, it should be freed by calling LBitmapRgn::Free.
nRet = LeadBitmap.Load(MAKE_IMAGE_PATH(TEXT("image2.dcm")), 0,ORDER_BGR);
pRect.left = 50;
pRect.top = 50;
pRect.right = 125;
pRect.bottom = 65;
nRet = LeadBitmap.AutoSegment(&pRect, 0);
