How to use Python for image processing?
Article Introduction：Python mainly uses two major libraries Pillow and OpenCV for image processing. Pillow is suitable for simple image processing, such as adding watermarks, and the code is simple and easy to use; OpenCV is suitable for complex image processing and computer vision, such as edge detection, with superior performance but attention to memory management is required.

H5 WebAssembly for Image and Video Processing
Article Introduction：WebAssembly (Wasm) is a binary instruction format suitable for image and video processing due to its near-native execution speed. 1. It supports compiling into intermediate formats in multiple languages, and runs efficiently in the browser; 2. Image and video processing involves a large amount of calculations, and Wasm is more efficient than JavaScript; 3. Select language and tool chain when using it, encapsulate functions to receive image data, and JS passes data to Wasm for processing and then passes the results back; 4. Video processing requires controlling frame rate, synchronization and memory management, JS grabs frames and passes them to Wasm for processing and then synthesis; 5. Pay attention to data format conversion, memory allocation and release, performance bottleneck positioning, and browser compatibility issues.

How to use OpenCV with C for image processing?
Article Introduction：Using OpenCV and C for image processing is not complicated. You can quickly get started by mastering the basic process and common functions. 1. Installation and environment configuration: Ensure that OpenCV is installed correctly, Linux can be installed with package manager, Windows can use vcpkg or manually configure the path, and test whether it is normal through a simple program; 2. Basic operations of images: use cv::imread() to read, cv::imshow() to display, cv::imwrite() to save images, and pay attention to the necessity of path judgment and waitKey(); 3. Common image processing operations: including grayscale, Gaussian blur, Canny edge detection and threshold processing, which are usually used in the preprocessing stage; 4. Custom convolution kernel
