An information processing apparatus selects a proper content that well matches preference of a user and recommends it. A matrix calculator acquires M (one or more) feature vectors CCV whose elements are given by weight values assigned to a total of N (two or more) pieces of content meta information and context information. The matrix calculator produces a matrix CCM whose columns are given by the M feature vectors CCV and converts it into an approximate matrix CCM* by modifying the weight values of the respective elements of the M feature vectors CCV such that correlations of elements among the M feature vectors CCV are emphasized. Based on the approximate matrix CCM*, a user preference vector (UPV) generator produces a user preference vector UPV*. A matching unit calculates similarity between the user preference vector UPV* and a feature vector CCV produced from new content meta information or context information.

Image encoding apparatus, image decoding apparatus, control method therefor, computer program, and computer-readable storage medium

InactiveUS20060210176A1Efficiently natural imageNumber of appearance is limitedCharacter and pattern recognitionDigital video signal modificationPattern recognitionLossless coding
According to this invention, while the encoding efficiency of image data (e.g., a natural image) substantially maintains the conventional one, an image (e.g., a CG image or text document) having a small number of appearance colors is losslessly encoded at higher compression ratio. For this purpose, pixel data are input in the raster order and temporarily stored in a buffer. Pixel data at positions having undergone encoding are stored. A neighborhood matching determination unit generates first information representing whether a pixel having the same color as that of the pixel of interest exists in neighboring pixels a, b, and c, and second information for specifying whether a pixel having the same color as that of the pixel of interest exists, and if the pixel having the same color exists, specifying the neighboring pixel. A pixel matching detection unit counts the number of colors contained in the neighboring pixels a, b, and c, and generates information representing whether the number of colors is two or less, or three or less. On the basis of the first information and second information, a code generation unit outputs one or both of encoded data from a matched-pixel position encoding unit and prediction error encoding unit.
