Super resolution reconstruction algorithm of video image based on deep self encoding learning

摘要

Super resolution reconstruction of video image is a research hotspot in the field of image processing, and it is widely used in video surveillance, image processing, criminal analysis and other fields. Super resolution image reconstruction can reconstruct a high resolution image from low resolution images, and this technology has become a research hotspot in the field of image processing. In recent years, deep learning has been developed rapidly in the field of multimedia processing, and image super resolution restoration technology based on deep learning has gradually become the mainstream technology. In view of the existing image super-resolution algorithm problems, such as more parameters, larger amount of calculation, longer training time, blurred image texture, we use the deep self-coding learning method to improve it. We analyze the advantages and disadvantages of the existing technology from the network type, network structure, training methods and so on, and sort out the development of the technology. The experimental results show that the improved network model achieves better super-resolution results, and the subjective visual effect and objective evaluation index are improved obviously, and the image sharpness and edge sharpness are improved obviously.
