摘要： To provide a motion vector detection device capable of rapidly and accurately detecting a main motion vector from plot data on a computer screen. An edge extraction unit (201) extracts edge points from each of a previous frame and a current frame. A feature point extraction unit (202) extracts, as a feature point, an edge point which is uniquely determined based on a relative positional relationship with another at least one edge point within a frame to which the edge points belong, from among a plurality of extracted edge points. A feature point pair extraction unit (203) extracts, as a feature point pair, a pair of feature points having a common positional relationship, among pairs of a feature point of the previous frame and a feature point of the current frame. A motion vector calculation unit (240) calculates, as a motion vector, a difference between coordinate values of the feature point pair extracted from the previous frame and the current frame.

摘要： An image is divided into subbands by wavelet transform using the Haar function as the base, and the lowest-frequency LL subband is entirely encoded. LH, HL, and HH subband coefficients which belong to the wavelet decomposition level of each hierarchy are encoded such that coefficients at the same spatial position are encoded based on a resolution or quantization accuracy mapping at each spatial coordinate. Additionally, an updated region detecting means detects an updated region from a plurality of sequential frames forming the two-dimensional signal, and obtains a changing period during which a signal value changes in each region. A resolution or quantization accuracy is set for each spatial coordinate based on the changing period, and a coefficient map is generated in which the resolution or quantization accuracy of the updated region differs from that of a region other than the updated region.

摘要： This moving image coding device has an update region detection unit, a coding target region detection and cache update unit, and a coding unit. The update region detection unit compares a reference frame and a current frame, and detects an update region that a pixel value changed. The coding target region detection and cache update unit replaces an image of an update region in the reference frame with an image in a cache frame, and thereafter, detects a region that a pixel value changed as a coding target region and stores an image of a region that a pixel value did not change for a predetermined past period in the image of the update region in the reference frame before the replacement, into the cache frame as an image of a stable region. The coding unit codes an image of the coding target region and cache information.

摘要： The moving image region detection device includes an updated block detection means, a natural image updated block determination means, and a moving image block extraction means. The updated block detection means compares pixel values between a frame of an input video and the previous frame, and detects a block including a pixel in which a value having been changed, as an updated block. The natural image updated block determination means calculates an index value representing a degree of continuity of changes in pixel values in the updated block, compares the calculated index value with a threshold, and determines whether it is an updated block of a natural image. The moving image block extraction means extracts a block determined to be an updated block of a natural image a given number of times or more in most recent frames including the frame, as a moving image block of a natural image.
