- 摘要:
- 图像在采集传输过程中会产生退化,退化主要分为视觉效果退化以及分辨率的退化。提出一种改进边缘加强的超分辨率算法,对图像进行边缘估计以及自适应预加重插值,利用小波方法处理生成文章中的算法得到的图像,使得加强后的图像获得较好的视觉效果,同时使加强后的图像的PNSR以及MSE优于其他此类算法。不仅使得到图像更加接近于原图像,还要消除因为插值导致低通带来的后果,使图像更加清晰,所以增加了梯度值的比较。从主观评价、客观评价(PNSR、MSE、梯度)验证了算法确实有更好的性能。
- Abstract:
- During the process of image acquisition, the image will be degraded. The degradation can be divided into visual degradation and resolution degradation. We propose an improved super-resolution algorithm for edge enhancement in this paper, we firstly make edge estimation for image and then have adaptive pre-weighting interpolation, the wavelet method is used to deal with the image generated by the algorithm lastly. The enhanced image can obtain better visual effect, and the PNSR and MSE of the enhanced image are superior to other algorithms.This paper not only needs to make the image closer to the original image, but also eliminates the consequence of low pass caused by interpolation and makes the image clearer. So adding the comparison of gradient values. From subjective evaluation, objective evaluation(PNSR, MSE, gradient), it is proved that the algorithm has better performance.
