一种自动提高图像信噪比的方法
A Method of Automatically Improving SNR of Image
摘要
Abstract
The signal-to-noise ratio is an effective way of measuring the effect of image processing and one of significant foundation of image identification. However,the SNR measure result often leads to inconsistent phenomenon with the visual effect. Aiming at the issue which the original calculation formula of the SNR makes high similarity between some images and original image that results in low SNR,a proportional coefficient is obtained automatically through analyzing the original and the results image. Each pixel of the results im-age multiplied by the coefficient,can get an image with high SNR,also can change the traditional SNR calculation formula which calcu-lates to results image by using new calculation formula of the SNR to get a higher signal-to-noise ratio and will get a higher calculation result by using new calculation formula of the SNR than original's. The theory analysis and experiment results demonstrate that the effec-tiveness of algorithm proposed in this paper is improved.关键词
