virtual L_INT LBitmap::SignalToNoiseRatio(SNR)
Finds the signal to noise ratio (SNR) of the Bitmap.
|SNR||Pointer to a variable to be updated with the SNR value.|
The function was successful.
An error occurred. Refer to Return Codes.
Calculates SNR as the 10*log10 of the real value. This value gives an indication for the homogeneity of adjacent pixels in image.
This function can only process entire images. It does not support regions.
This function supports 24 and 36-bit color images and 8 grayscale images.

This example loads a bitmap and find signal to noise ratio.
L_INT nRet ;
LBitmap LeadBitmap ;
nRet = LeadBitmap.Load(MAKE_IMAGE_PATH(TEXT("cannon.jpg")), 0,ORDER_BGR);
/* Apply L_SignalToNoiseRatio and find S/N ratio*/
L_FLOAT SNR ;
nRet = LeadBitmap.SignalToNoiseRatio(&SNR) ;
return nRet ;
