摘要： An image processing device, an image processing program and an image processing method for forming a composite image by superimposing an overlay image on a base image. Fixed length compressed image of the base image fixed length compressed data of the overlay image are formed by dividing data of the base image and data of the overlay image respectively into a plurality of blocks and by encoding a statistical parameter of each block, including a gray level representing the block, and quantization levels of respective pixels in the block. Then, while the fixed length compressed data is being checked in a block-by-block manner, the fixed length compressed data of the base image is taken in if the gray level of the block of the overlay image is 0, and the fixed length compressed data of the overlay image is taken in if the gray level of the block of the overlay image is not 0.

摘要： An encoded code stream is searched for a frame generally coincident with a specific frame without having to decoding the frame to its original image. The present invention provides an image search device that searches an object encoded code stream formed by compression coding of a plurality of frames for a frame generally coincident with a specific one, which includes a decoder for making entropy decoding of the object encoded code stream to generate quantization coefficients of each frame, a matching unit for making matching between the quantization coefficients of the specific frame and those of each frame which are generated by the decoder and correspond in sample position to those of the specific frame, and a judging unit for judging, based on the result of matching, whether the frame is generally coincident with the specific one.

摘要： A predetermined area of input image data (100) is read and stored into a memory section (1). As soon as data is stored in the data read memory section (1), wavelet conversion filtering is performed on the image area, in the horizontal or vertical direction, by a wavelet conversion section (5). The wavelet conversion section (5) comprises a fixed-point type wavelet conversion section (3) and an integer type wavelet conversion section (4). Data from the data read memory section (1) is switched and controlled by a switching section (2), and supplied to either the fixed-point wavelet conversion section (3) or the integer type wavelet conversion section (4).

摘要： In an image encoder, a first quantization section which is selected when normal image quality is required performs quantization by dividing a wavelet transformation coefficient by a quantization step size and by thereafter rounding down a fraction thereof. On the other side, a second quantization section which is selected when high image quality is required performs quantization by dividing a wavelet transformation coeffient by a quantization step size, by adding 0.5 to the addition result, and by thereafter rounding down a fraction thereof. Therefore, the width of a dead zone where coefficients are quantized to a value of 0 is narrower than that in the first quantization section, and higher image quality is obtained accordingly.
摘要翻译：在图像编码器中，当需要正常图像质量时选择的第一量化部分通过将小波变换系数除以量化步长进行量化，然后向其舍入其分数。另一方面，当需要高图像质量时选择的第二量化部分通过将小波变换系数除以量化步长进行量化，通过将0.5加到加法结果上，然后向其舍入其分数。因此，系数被量化为0的死区的宽度比第一量化部分的宽度窄，从而相应地获得更高的图像质量。

摘要： In an image encoder (1), a quantizer (11) makes a quantization-step size set for each of low-frequency subbands whose resolution level belongs to a predetermined resolution level coincide with a quantization-step size set for each subband to encode an original image having the resolution level as it is. A low-pass rate controller (17) provides a rate control for the bit rate of arithmetic code D16 in all code blocks in a low-frequency subband to be less than a predetermined target bit rate. A high-pass rate controller (18) provides such a rate control that the bit rate of arithmetic code D17 in all code blocks in other subbands than the low-frequency subbands will be less than a target bit rate, that is, a bit rate resulted from subtraction of a bit rate D18 having actually occurred in the low-frequency subbands from a final target bit rate.

摘要： A wavelet encoding method and apparatus and a wavelet decoding method and apparatus for pictures. A input picture is split into plural tile pictures and wavelet transform is applied to input pictures on the tile picture basis to effect the encoding. For wavelet transform, pixels lying on the outer side of a given tile picture are symmetrically expanded and convolved. This enables marked memory capacity reduction, while eliminating constraint conditions for the number of times of wavelet splitting.

摘要： A technique for encoding an interlaced picture comprises the steps of rearraying the interlaced picture on a scanning line basis, splitting the re-arrayed picture into a plurality of first block portions and splitting the re-arrayed picture into a plurality of second block portions. Each second block portion is transform processed to generate a plurality of transformed block portions, and it is determined which transformed block portion is most similar to a preselected first block portion. The second block portion corresponding to the determined transformed block portion is selected, and block position information indicating the position of the selected second block portion and a transformation parameter representing the transform processing of the selected second block portion are output. A technique for producing a decoded picture from the encoded interlaced picture comprises the steps of receiving a code including block position information indicating the position of a pre-transformed block and the aforementioned transformation parameter. Defined transformation processing is performed on a block identified by the block position information and is based on the transformation parameter. A decoded picture is constructed from the transformation processed blocks, and the decoded picture is re-arrayed on a scanning line basis and output.
