1Introduction to mean-value filteringFiltering is the operation of filtering a particular band frequency in a signal, which is a technique for extracting useful signals from a receiving signal containing interference.Mean filter is a typical linear filtering algorithm, which refers to the image of the target pixel to a template, the template includes its surrounding neighboring pixels (such as the 3x3 templ

Image Filter art-detail-preserving polishing C # Program Implementation
Here, we also use the ZPhotoEngine library for implementation. After all, the effect in this library is almost the same as that in PS. For more information, I will give it at the end of the article, the steps for skin polishing are as follows:
1. blur the surface of copy a of the source image
-function one has the following values to choose from:
Grayscale Grayscale
Sepia Brown (for professional pointing translator)
Saturation of saturate
Hue-rotate Hue Rotation
Invert inverse color
Opacity transparency
Brightness brightness
Contrast contrast ratio
Blur Blur
Drop-shadow Shadow

In fact, if you have read the previous articles about black and white images and reversed images, you can easily process some simple images, because those only obtain the pixel values of the coordinates first, and then process these values. However, the filter effect is similar. The function to implement the filter effect is as follows,

regsvr32 Proppage.dll
regsvr32 directSpy.dll, as shown in figure:
Reboot the system when finished.
