Design of Online Teaching Platform for Packaging and Printing Course Based on Joint Image Denoising

With the development of modern technology, online teaching platform began to appear, but the traditional design of the platform function is not perfect, resulting in the presence of noise when the platform displays teaching images, affecting students’ interaction in the platform, so the design of online teaching platform for packaging and printing course based on joint image denoising. This design plans the overall design scheme in advance, sets the corresponding teaching interaction function according to the results of the basic module division of the platform, and optimizes the packaging and printing teaching information combined with image denoising method. Experimental results: compared with the traditional platform, the design of the platform in the display of teaching images, image peak signal-to-noise ratio is higher, clear teaching images stimulate students’ learning enthusiasm, so as to strengthen the communication and interaction in the teaching platform.
