Pillow composite

The Image module of the image processing library Pillow PIL of Python provides composite for pillow composite two images according to a mask image. Note that composite is a function to composite two images of the same size, pillow composite.

If you have two images A and B, you alpha-composite A over B, it will create an effect that you can see both image A and B in the resulting image, as if A has transparency and you can see through A and also see B. Suppose a is the src image, b is the destination image, we composite a over b. The equation for alpha value and pixel value of the generated image are:. So it is easy to see that the resulting pixel value is a linear combination of pixel value from a and b. To test the correctness of the above equations, use the above script.

The Image module of the image processing library Pillow PIL of Python provides composite for compositing two images according to a mask image. Note that composite is a function to composite two images of the same size. Use the paste to composite images of different sizes. There are three parameters for composite. All three must be Image objects, all of the same size. ImageDraw and ImageFilter are used when drawing a figure and creating a mask image. When reading an image file and using it as a mask image, they may be omitted. This time, the second image is reduced by resize to match the size. If you cut out part of the image and adjust the size, use crop. See the following article.

Since PIL is no longer under development, Pillow is now widely used. Although advanced image processing face recognition, optical flow, etc. Because Pillow is simpler and easier to understand than OpenCV, it is better to use it depending on the purpose. See the following link for individual articles that explain various processes such as resizing and trimming.
