摘要： The invention provides a motion vector conversion method by which the coding efficiency in image coding of MPEG4 in an image information conversion method can be further augmented. In the motion vector conversion method for an image information conversion method, every other one of P frames of a bit stream of MPEG2 is dropped to produce a bit stream of MPEG4 of a reduced frame rate and a low bit rate. Also for motion vector modification, information of each of macro blocks and between blocks in the inputted bit stream representative of image compression information of MPEG2 is stored in advance, and motion vectors of a P frame immediately preceding to each P frame to be dropped are duplicated based on the stored information. Then, the duplicated motion vectors are extended to twice in the temporal direction to produce motion vectors of MPEG4 converted from an intra-frame of MPEG2.

摘要： An apparatus for detecting a moving object in motion video comprises a macro-block determining section for determining the background/non-background of each macro-block of a reconstructed video signal from a video decoder section which decodes encoded data obtained by compression-encoding a motion video signal, a moving object determining section for determining an area of the moving object from the result of the determination on the background/non-background, and a moving object combination display for displaying information indicating the area of the moving object on a display screen for the reconstructed video signal. The macro-block determining section determines if a macro-block represents a background area or a non-background area, based on mode information from the video decoder section and a cross correlation value between a present frame of the reconstructed video signal and a signal of a frame preceding the present frame by one frame, obtained by a first cross correlation calculator, and a cross correlation value between the present frame of the reconstructed video signal and a background video signal stored in a background memory, obtained by a second cross correlation calculator.

摘要： A digital image coding apparatus includes a first encoder for performing difference coding to a low-resolution texture signal, and a second encoder for performing difference coding to a high-resolution texture signal. When difference coding is performed on a high-resolution texture signal using its prediction signal, padding processing in which insignificant sample values of a low-resolution texture signal that has been regenerated by the first encoder are replaced with pseudo sample values that are obtained from significant sample values thereof. A padding unit in the first encoder generates the prediction signal corresponding to the high-resolution texture signal on the basis of the regenerative low-resolution texture signal which has been subjected to the padding process.

摘要： In a method for encoding a binary alpha block (BAB) within a current frame based on the current frame and a previous frame, even-numbered horizontal lines of the BAB are sampled to generate a first block and even-numbered vertical lines of the first block are sampled to generate a first sample block. And then, a reconstructed first block and a reconstructed BAB are generated by inserting reconstructed vertical and horizontal lines sequentially at locations of odd-numbered vertical and horizontal lines thereof, respectively. In the above, binary values of first and second binary pixels of the reconstructed vertical and horizontal lines are made by using corresponding first and second context values based on predetermined probability tables, respectively, wherein the corresponding first and second context values are calculated by using the context values of binary pixels within the previous frame located at identical positions to the first and second binary pixels, respectively; and context values of binary pixels located at surrounding positions of the first and the second binary pixels except a binary pixel below the first binary pixel and a binary pixel right to the second binary pixel, respectively.

摘要： A method and apparatus for coding and decoding an image signal, and also a recording medium for storing a coded image signal wherein low resolution image signal including a plurality of pixels and also a high resolution image signal including a plurality of pixels are received. The low resolution image signal is coded thereby generating a resultant coded low resolution image signal. The high resolution image signal is predicted from the low resolution image signal thereby generating a predicted high resolution image signal. After that, the predicted high resolution image signal is divided into a plurality of blocks each including n.times.m pixels. The feature of each block is detected and a judgement code corresponding to the detected feature is generated. Then a coding table is selected in accordance with the judgement code. The n.times.m pixels in the corresponding block of the high resolution image signal are coded using the selected coding table to generate coded data. In the above process, instead of directly coding the high resolution image signal, the difference between the high resolution image signal and the predicted high resolution image may be coded. The image signal can be compressed in a highly efficient fashion by coding the low resolution image signal and high resolution image signal.
