IMAGE SUPER-RESOLUTION RECONFIGURATION SYSTEM AND METHOD

摘要

Disclosed are an image super-resolution reconfiguration system and method. The method comprises: conducting edge detection on a low-resolution image to be processed, and obtaining an edge pixel frame; keeping the detected edge pixel information unchanged, and conducting interpolation amplification on the edge pixel frame, the amplified image being twice as large as an original edge pixel frame in both the horizontal direction and the vertical direction; and according to different pixel edges, conducting interpolation compensation on an interpolated interpolation pixel so as to obtain a high-resolution image. In the method of the present invention, firstly, edge detection is conducted on an image; then, an edge image frame picture is amplified to be twice as large as an original image through interpolation amplification, and the edge pixel information is directly kept, the process can guarantee the clarity and integrity of edge contours and enhance the picture contrast without sacrificing the image quality, and then, interpolation compensation is conducted on the previous interpolation pixel using an optimized method, the influence of edge pixels and surrounding pixels are comprehensively taken into account in the process thereof, so that the zigzag phenomenon in output pictures is obviously reduced.
