According to some embodiments, a computer-implemented method includes receiving a request at a content delivery service to encode a video, performing a discrete cosine transform (DCT) on a first pixel block of a frame of the video to generate a first DCT block, and on a second spatial pixel block of the frame, spatially offset from and overlapping with the first pixel block, to generate a second DCT block, performing a wavelet transform on the first DCT block and on the second DCT block to generate wavelet coefficients, performing a filtering on the wavelet coefficients to generate filtered wavelet coefficients, performing an inverse wavelet transform on the filtered wavelet coefficients to generate a filtered DCT block, performing an inverse discrete cosine transform on the filtered DCT block to generate a filtered pixel block, encoding the filtered pixel block to generate an encoded video, and transmitting the encoded video to a viewer device or to a storage location."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Perceptually motivated video pre-filter","description":"Techniques for providing perceptually motivated video pre-filtering are described.
