Abstract:

Traditional scene adaptive nonuniformity correction methods generally suffer from the over smooth and residual nonuniformity in the corrected results. In view of this, a cascade residual learning based nonuniformity correction method is presented. This method uses the multiscale feature extraction unit to fuse the extracted features and employs the residual learning strategy to deal with the overfitting problem. Experimental results validate that the proposed method yields nearly 5dB improvement in the average peak signal-to-noise ratio (PSNR) as compared to the traditional scene adaptive correction methods. Moreover, its visual effects are clearer and sharper.

Key words: deep learning, nonuniformity correction, image denoising, infrared image processing
