摘要： The present invention is directed to an apparatus for motion segmentation in the field of motion detection, whereby an initial motion map is processed to a more accurate final motion map which identifies the non- and the movement of pixels between at least two successive images, said apparatus comprising a processing-segmentation device and a combination-logic device. In this apparatus the initial motion map is processed to three different feature maps, describing static edges, moving edges and moving flat areas between at least two successive images, respectively. The present invention is further directed to a corresponding method adapted for motion segmentation in the field of motion detection.

摘要： From first and second image data descriptive for first and second pictures captured in a first temporal distance to each other, a global motion estimator unit (110) estimates a global motion vector, which is descriptive for sign and amount of a global displacement of image portions that move with respect to a first axis both when the move at the same speed and when they move at different velocities. The global motion vector improves estimation of fast moving objects. The global motion vector estimation may rely on the evaluation of a plurality of one-dimensional profiles.

摘要： The invention relates to an interlaced to progressive conversion method and system by use of an interpolation algorithm (IPC algorithm) which is scaleable with several levels or modes with an increasing computational complexity depending on increasing availability of resources, i.e. computation power, available memory and available memory bandwidth. An IPC mode control can be implemented as a decision table. Peferably, at least five levels of the algorithm can be scaled beginning with line repetition (lowest level), linear interpolation (lower level), median inter-field computation with a three-tap or a five-tap median operator (medium level) and a combination of a linear interpolator and a median interpolator, eventually in combination with edge detection (higher levels of the scaleable algorithm).

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.

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.
