A multi-model restoration algorithm for recovering blood vessels in skin images

作者：

Highlights：

• An algorithm is proposed to restore JPEG images for visualizing blood vessels.

• A clustering scheme based on properties of JPEG compression is designed.

• SSIM, PSNR and CMC curves are used to evaluate the algorithm.

• The algorithm outperforms the state-of-the-art deblocking methods.

• The algorithm is tested on images collected from the Internet.
