    摘要: The present invention relates to a coding parameter independent method for reduction of blocking artefacts in a compressed image or video signal. For this purpose, the image is analysed in the vicinity of the block boundaries in order to measure the existence and strength of blocking artefacts and to detect image areas. Based on the analysis result map information for each pixel adjacent to a block boundary is generated. The filter mode for each block boundary is adaptively determined dependent on the map information and the image is filtered depending on the chosen filter mode.

    摘要: The present invention relates to an image processing method and to a device to process a moving image, which is shot by a predetermined video shooting device, in increments of access units. The imaging blur is represented by a corresponding low-pass filter showing the properties of imaging blur which occurs at the time that said moving image is shot with said video shooting device. According to the present method an inverse filter having inverse properties as to said low-pass filter is generated. A processing is performed to apply said inverse filter to said access unit to be processed. Hereby, the step of generating an inverse filter includes an iterative algorithm in the frequency domain based on the original blurred image and the point spread function.
