摘要： A coded moving-picture signal is decoded by a resolution-converting motion compensation process and a resolution-converting inverse discrete cosine transform, both of which decrease the resolution of the picture, thereby reducing the amount of reference picture data that has to be stored and accessed. The reference picture data may also be stored in a compressed form. The resolution conversion and compression processes may also be used in the coding of the moving-picture signal. The resolution-converting inverse discrete cosine transform may be performed by output of intermediate results that have not been combined by addition and subtraction in a butterfly computation.

摘要： An image signal is transformed by at least two different mathematical transformations to obtain at least two different transformed signals. A selected one of the transformed signals is quantized and coded, the selection being made so as to minimize the size of the coded data. The selection is made by comparing the energy convergence rates of the transformed signals, or by quantizing all of the transformed signals and comparing the amounts of non-zero quantized data, or by quantizing and coding all of the transformed signals and comparing the coded data sizes directly.

摘要： An image compression apparatus has a separation section for performing processing for dividing image data into a plurality of data blocks, an orthogonal transformer for orthogonal-transforming each data block, a bit allocation table for storing data representing the number of bits allocated in accordance with the frequency component of the orthogonal-transformed data output from the orthogonal transformer, an arithmetic operation circuit for calculating an amplitude probability density function of an identical frequency component of the orthogonal-transformed image data for each pixel, and calculating a quantization limit band causing a mean square error to be minimized in acordance with the calculating amplitude probability density function and the bit-number data from the bit allocation table, and a band limit table for storing the quantization limit band data. A quantizing circuit quantizes the orthogonal-transformed block information from the orthogonal transformer in accordance with the data stored in the allocation table and the band limit table.

摘要： Behavioral blocking of overlay-type identity stealers is achieved by detecting a transactional web page session, evaluating a property of a window corresponding to a process running on the computer system, and then, based on a result of the evaluation, blocking a behavior of the process for a duration of the transactional web page session. The evaluation of the property window involves determining whether the window exhibits one or more characteristics representing activity of an overlay-type identity stealer.

摘要： A shape adaptive wavelet transform is performed on a digitized image signal representing an image. First, a shape information is obtained about the image, and the shape information is applied to a shape adaptive wavelet filter. The shape adaptive wavelet filter detects a starting point and an ending point of the image. The digitized image signal is divided into a low-frequency component and a high-frequency component. Then each frequency component is sampled, using the shape information. The shape adaptive wavelet filter then generates converted shape information indicating the shape for each sampled frequency component.

摘要： A digitized image is divided into blocks and a wavelet transform is performed, producing wavelet blocks which are quantized, scanned into linear sequences, and then coded. The scanning of each wavelet block starts with a purely low-frequency element. The high-frequency elements are scanned in a sequence that depends on the occurrence of non-zero elements among the high-frequency elements. When a non-zero element is scanned, this information is used to proceed quickly to related high-frequency elements. This scanning method tends to produce a linear sequence in which non-zero elements are clustered together. Such sequences can be coded efficiently.

摘要： An N-level wavelet transform is executed on an image signal representing an image having a first dimension and a second dimension. First, an N-level one-dimensional wavelet transform is executed in the first dimension, thereby generating an intermediate signal which is temporarily stored in a memory device; then an N-level one-dimensional wavelet transform is executed on the intermediate signal in the second dimension. The image signal may be accompanied by shape information describing the shape of the image, in which case each N-level one-dimensional wavelet transform is executed by a series of N one-level wavelet transforms, with alteration of the shape information when each one-level wavelet transform is performed.
