SciSmart Applications——Image Filtering

     While the process of imaging, transmission and description, the image will be disturbed from various signals thus the noise would be generated. Likewise, the noises always appear as isolated pixel points or pixel blocks, which have strong visual effects on the image. In digital image processing, image filtering has always been adapted to process such image.

 Image filtering is a process, which can restrain the noise signal of the image and ensure the detail of the image is not destroyed. The filtering methods include mean filter, median filter, Gaussian filter, Laplace filter and Sobel filter etc.

Application: Restrain the noise signal.
