How To Reduce Noise Using The Average Filter Of Image Processing? How To Reduce Noise Using The Average Filter Of Image Processing? ¶ Introduction The photograph has many noises. We can reduce the noise using the average filter. There are a 3 by 3 matrix matching the photograph. We are amount of the pixels of the 3 by 3 matrix. Then, we divide by 9. The result is the center pixel value of the 3 by 3 matrix. We will rewrite the result into the photograph. Equipment Operation System: Microsoft Windows 7 (64 bit) Development Utility: Microsoft Visual Studio 2010 Usage // The loop of the average filter. for ( int iI = 0; iI < 6; iI++) { // The height of the image. for ( int iY = 1; iY < imageA->DibInfo->bmiHeader.biHeight - 1; iY++ ) { // The width of the image. for ( int iX = 1; iX < imageA->DibInfo->bmiHeader.biWidth - 1; iX++ ...
