Today to introduce a snow filter, you can make your summer photos instantly turned into a snowy scene Oh! First look at the following:The above three images are (a) the original image, (b) PS, (c) C # codeThis snow filter is also relatively simple, according to the previous steps, we introduced the PS implementation process and the code implementation process.The

First, the algorithmGaussian blur algorithm see: Gaussian blur, the basic idea is to use the Gaussian function, a coordinate point of all the neighborhood of the weighted average value of these points are set to the color values.The median filter algorithm is simpler: Set the average of all neighborhoods of a coordinate point to the pixel values of those points.Second, the code implementation of the algorithmGaussian function:To replace with a macro d

You can use AS3 or MXMLAS3 code to explain how to use a filter. First, let's take a look at the fuzzy filter. This filter is very simple. First, you need to determine the Blur degree of the image in the direction of X and Y. Of course, there are still quantities, the quantity attribute determines the number of iteratio
