A POCS Algorithm for Super-resolution Image Reconstruction Based on Edge Maintenance
Shenghong Li · Information Security and Communications Privacy · 2009
The traditional super-resolution image reconstruction algorithm leads to the blur edge of reconstructed high image.Based on analysis of the reason for leading to the blur edge of high-resolution reconstruction image,a new image interpolation based on gradient is proposed,which keeps much information of the image edge.This new image interpola-tion is used to get the original value of the POCS.The experimental tests indicate that this algorithm could significantly improve the quality of the reconstructed image.
