Abstract: A method including receiving an audio signal, generating a transformed audio signal by transforming the audio signal using a plurality of windows each separated in time, generating an interpolated audio signal by interpolating the transformed audio signal, generating a separated audio signal by applying a mask to the interpolated audio signal, and compressing the separated audio signal.

Abstract: A method includes obtaining respective filtered pixels for pixels of a reconstructed image; and obtaining an edge-preserved image using the respective filtered pixels. Obtaining the respective filtered pixels includes, for each pixel of the reconstructed image, obtaining a respective filtered pixel by selecting a pixel patch including the pixel and first neighboring pixels of the pixel that are at relative neighboring locations with respect to the pixel; calculating respective weights for the first neighboring pixels; and filtering the pixel using the respective weights of the first neighboring pixels and the neighboring pixels to obtain the respective filtered pixel.

Abstract: A method for decoding an image block includes receiving a quantized transform block; generating a decoded block from the quantized transform block; applying an edge-preserving filter to the decoded block, to obtain an edge-filtered decoded block; obtaining a transformed edge-preserved block using a transform type and quantization data to the edge-filtered decoded block; clamping a value of the transformed edge-preserved block to a corresponding value of the quantized transform block to obtain a smoothed transform block; and inverse transforming the smoothed transform block to obtain an edge-preserved smoothed block. The applying an edge-preserving filter to the decoded block includes determining respective patch-based distances between a pixel of the decoded block and neighboring pixels; determining respective weights corresponding to the respective patch-based distances; and filtering the pixel using the respective weights and the neighboring pixels.
