Neighbor pixels having greatest similarities and correlations with a central pixel are exploited to develop a diamond-shaped window for performing a noise reduction procedure. The diamond-shaped window merely covers significant pixels required by the noise reduction procedure to improve the performances in reducing noises. Besides, a size of the diamond-shaped window is adjustable according to the noise ratio of noises hidden in the processed image. The noise reduction procedure utilizes the diamond-shaped window instead of a conventional square-shaped window to improve the performance in noise reduction, and to avoid possible picture quality losses of the original image caused by redundant pixels covered by the square-shaped window. |
