摘要： A method for compressing and decompressing video image data, wherein the contours of image structures are determined in a basic analysis of the video data contained in a video image by means of sudden modifications of brightness and/or tristimulus value in adjacent pixels; the contours thus found are respectively described in segments by means of a parameterized mathematical function and are defined as objects; a color dominance and a color characteristic is determined for the individual objects, in addition to the position and extension of the individual objects and a structural function, such that differential modifications in brightness, size, position and orientation of said objects are determined in sequential analyses of video images, taking into account common contours of contiguous objects. The objects thus defined are placed in a structured base frame or sequential frame and are prepared. Contour analysis and structural analysis is carried out by means of neuronal networks.

摘要： Original digital data stored in a memory is searched for on the basis of an input image, difference information is extracted by comprising the retrieved original digital data and the input image, and the difference information is composited to the original digital data. Furthermore, digital data generated by composition is stored in the memory. Also, original digital data stored in a memory is searched for on the basis of an input image, and when no original digital data is retrieved, the input image is converted into vector data, and the image that has been converted into the vector data is stored as digital data in the memory. Moreover, region segmentation information obtained in a block selection step and an input image are composited, the composite image is displayed on an operation screen of an MFP, and a rectangular block to be vectorized is designated as a specific region from the displayed region segmentation information. As a method of designating the specific region, for example, the user designates one or a plurality of rectangular blocks in an image using a pointing device.

摘要： In an object region data generating method for moving picture, an object region is approximated with a polygon in each frame (S11). Each vertex of the polygon in one frame is associated with each vertex of the polygon in adjacent frame based on the distance between the vertexes (S12). A trajectory of the vertex is obtained on a time-series variation of the associated vertexes (S13). The object region data is generated based on the trajectory of the vertex.

摘要： A method for coding multiple layer, vertex-based shape representation and bit stream scaleable shape includes selecting vertices in a hierarchical scheme; defining multiple layers of vertices; arranging M layers of vertices in order, from the most salient layer to the least salient layer; placing vertices in their natural order along their image contour within each layer; storing vertices from each layer separately; and recording vertex order information for each vertex in each layer of vertices. Four variations of the method for multiple layer vertex representation and coding are disclosed where the correct order information is coded for correct reconstruction of the shape information.

摘要： Ce procédé consiste à transformer chaque information relevée en un signal sinusoïdal (f s (t)) dont l'amplitude maximale représente la magnitude d'un vecteur qui représente cette information et dont la phase représente l'angle (α) de ce vecteur (V), à détecter ladite amplitude maximale (A i,j ), à comparer cette amplitude maximale à un signal en forme de rampe (r) et à engendrer une première impulsion (a i , a j ), lorsque le signal en forme de rampe (r) est égal à l'amplitude maximale, à engendrer une seconde impulsion (p i , p j ), lorsque la fonction (f s (t)) passe par une valeur nulle après la génération de la première impulsion, lesdites première et seconde impulsions (a i , a j , p i , p j ) formant par leur position dans le temps un encodage temporel de la magnitude et de l'angle dudit vecteur (V) et donc de ladite information.

摘要： A contour of an object in an image having one or more objects therein is reconstructed based on encoded contour data for the contour and a previously reconstructed contour for an object included in the image. The method, first, decodes the encoded contour data for a current contour to thereby provide a reconstructed current contour and checks whether the reconstructed current contour overlaps with any previously reconstructed contours. If none of the previously reconstructed contours overlaps with the reconstructed current contour, the method sets the reconstructed current contour as a currently reconstructed contour. If, otherwise, the reconstructed current contour overlaps with a previously reconstructed contour, the reconstructed current contour is modified not to overlap with the previously reconstructed contour and the method sets the modified contour as the currently reconstructed contour.

摘要： A method for encoding a video signal of a contour of an object based on the iterated refinement technique determines a plurality of vertices on the contour; and calculates a contour pixel bit-number required to encode all the contour pixels and a vertex bit-number needed to encode all the vertices. After generating a determination signal representing the smaller of the contour pixel bit-number and the vertex bit-number, the method encodes contour information representing the vertices or the contour pixels based on the determination signal to generate a coded data.
