Encoding and decoding using frequency-domain denoising are provided. Encoding and decoding using frequency-domain denoising may include identifying a current source block from a current source frame from a source video stream, generating a prediction block for the current source block, generating a ...
21: Unsupervised generative denoising (2021-0-Unsupervised Image Denoising with Frequency Domain Knowledge) 21: Non-learning + learning enhancement, compression and reconstruction method (2021-AF-A combination of learning and non-learning based method for enhancement, compression and reconstruction of under...
Since the existing hyperspectral image denoising methods suffer from excessive or incomplete denoising, leading to information distortion and loss, this letter proposes a deep denoising network in the frequency domain, termed D2Net. Our motivation stems from the observation that images from different hyp...
The decision of denoising algorithm is based on the application and the kind of noise present on the image. Every strategy has its own uncertainties, favorable circumstances and confinements. The thought behind these methods is to obtain better results in terms of quality and expulsion of various...
