摘要： The present invention prevents coding artifacts caused in applying image enhancement technologies to pictures that have been encoded and then decoded. A video decoder (200) decodes an encoded stream generated by encoding a prediction error that is a difference between an original image and a prediction image. The video decoder (200) includes: an entropy decoding unit (231) decoding the prediction error in the encoded stream; an adder (244) adding the decoded prediction error to a previously-generated decoded image to generate a decoded image; an image enhancement unit (260) performing a process of enhancing image quality of the generated decoded image to generate an enhanced image; and a mask construction unit (240) determining a weight coefficient for each image area based on the decoded prediction error. The image enhancement unit (260) generates an output image by computing a weighted sum of the decoded image and the enhanced image in accordance with the determined weight coefficient.

摘要： The present invention has been conceived to solve the previously described problems, and provides a texture representation method without any unnatural feeling while performing data compression equivalent to a conventional data compression or more. An input signal is separated in two frequency domains. The low-frequency component is faithfully coded by a conventional image/video coding apparatus. The high-frequency component is analyzed to compute representative texture parameters. Instead of faithfully coding the high-frequency component, only the computed texture parameters are stored or transmitted to a decoding apparatus. Then, the low-frequency component is reconstructed, whereas the high-frequency component is replaced by a natural texture that has been synthesized according to the texture parameters. The reconstructed low-frequency component and the synthesized high-frequency component are merged to generate an output signal.
