System and method for processing digital noise in a digital image |
摘要 |
A processing digital noise method generates a matrix according to pixel values of pixels of a digital image, and selects a sub-matrix from the matrix. The sub-matrix has the same dimensions as a digital noise sample and includes a pixel value of a pixel selected from the digital image. The digital noise sample is represented as a matrix composed of 0 and 1. The method compares the sub-matrix with the digital noise sample to determine whether or not all values in the sub-matrix and the digital noise sample are the same. If all values are the same, the method further searches 1 from the sub-matrix for locating digital noise of the digital image, and removes the digital noise of the digital image by changing the pixel values of the digital noise from 1 to 0. |
