Image processing technology covers a wide range of application fields, with in-depth research on various image theories, technologies, equipment, and a wide range of research fields. In order to facilitate researchers to visually and quickly analyze the effectiveness of relevant algorithms, an image processing simulation platform is designed using a GUI visual interaction interface. The design principles and processes are conceptualized, and the overall design of the platform is constructed. The functions of each sub interface are implemented based on the division of modules. The processing effects of different algorithms can be compared visually through running the results, and the application of image processing technology in license plate recognition can be demonstrated through comprehensive examples Comprehensive application in smart classroom attendance process. The test results of the simulation platform indicate that the image processing platform is easy to operate and expand, effectively assisting operators in deepening their understanding and application of image processing technology.
