Output result:

With this effect, you can easily draw a conclusion:
The center of the Offset is centered on each pixel. The four offsets are symmetric in the center, arranged in a circular direction of 45 degrees oblique, and 45 degrees horizontal and vertical offsets, respectively. The offset is 4 pixels.
We can guess how to overlay the data by taking the average value of the accumulated value after four offsets.

One important point is figuring out how to calculate the memory address of a point in the picture.
As shown in this image (the picture comes from that blog post), the address of the point in memory of the coordinates (X,Y) is Scan0 + (Y * Stride) + X * k. K is related

Use the following methods:

struct Swscontext *sws;
Sws= Sws_getcontext (W/12, H/12, Pix_fmt_rgb32, W, H, pix_fmt_yuv420p, 2, NULL, NULL, NULL);
Use:

For narrow convolution, the convolution is done from the first point, and each window slides a fixed stride. For example, the left part of the following figure is a narrow convolution. Then notice that the more times the edges are being rolled down the less. So there is a wide convolution method, can be seen in the convolution before the edge with 0 supplements, common in two cases, one is full complement, into the right part of the figu
