摘要
In the past few decades, denoising is one of the major portions in imaging analysis and it is still an ongoing research problem. Depending upon some pursuit methods an attempt has been made to denoise an image. The work comes up with a new methodology for denoising with K-SVD algorithm. Noise information has been extracted using the proposed approach. With reference to heap sort image patches are learnt using dictionary and then it is updated. Experimentation says that introduced approach reduces noise on test. The proposed approach is tested on test datasets and the proposed approach is found to be comparatively good than the existing works.
