Method for image resolution enhancement
First Claim
1. A method for image resolution enhancement, including the following steps:
- providing an original image;
utilizing a fuzzy analysis system to analyze the original image and classifying the original image into the one with edge quality and the other one without edge quality;
calculating the edge angle of the area classified to be with edge quality and processing the area with neural network interpolation;
processing the area classified to be without edge quality with bilinear interpolation; and
obtaining a high-resolution digital image after completing the whole original image processing.

Abstract
The invention provides a method for image resolution enhancement, which utilizes a fuzzy analysis system simulating the human vision system and uses the neural network as a basis for digital image interpolation. After an original image is inputted in, the image analysis module will divide and classify the original image, and then each of the image being classified will be processed by either the bilinear interpolation or the neural network interpolation. Because the fuzzy analysis system is configured according to the human vision system, and because the neural network is a model obtained from learning real natural images, the vision effect of the image enlarged through the processing method of the invention is very close to the real natural image.
