摘要： In an image processing apparatus, a moving picture storage module stores moving picture data. A scene designation module designates at least one scene in the moving picture data, and sets a key frame and importance level of the designated scene. A frame feature extraction module acquires an image feature amount of the designated key frame. A scene feature information storage module generates scene feature information including the duration, key frame, importance level, and image feature amount of the key frame of the scene designated by the scene designation module, and stores the generated information in a memory in correspondence with the moving picture data. Based on the scene feature information, digest playback for playing back only principal part of the designated moving picture data is executed, or desired moving picture data is found by a similar image search using the key frame.

摘要： This invention has as its object to allow high-precision and high-speed retrieval in consideration of position information of image feature amounts upon retrieving similar images based on image feature amounts, even when the position information includes some differences. To achieve such object, an image processing apparatus according to this invention has the following arrangement. That is, an image processing apparatus for calculating a similarity between different image data, includes a first generation unit configured to generate feature amount matrices on the basis of feature amounts of the image data acquired by dividing the different image data into a plurality of blocks, a calculation unit configured to calculate a distance between feature sequences which form the generated feature amount matrices by DP matching, and a second generation unit configured to generate a line penalty matrix by two-dimensionally arranging the calculated distances between the feature sequences, and calculates a similarity between the different image data by DP matching using the line penalty matrix.

摘要： An image search apparatus, which determines a similarity between an input query image and a registered comparison destination image and searches an image similar to the query image, extracts a plurality of corresponding pairs of feature points in two images based on feature points selected from the both images. A coordinate transformation coefficient to execute a coordinate transformation process is decided so that coordinates of the feature point of one of the two images match coordinates of the feature point of the other image, in relation to each pair. Only if an amount of transformation of coordinates satisfies the constraint conditions designated in advance, the coordinate transformation process using the coordinate transformation coefficient is executed in relation to the plurality of pairs of feature points, and coordinates of the feature points after the transformation of one image are compared with coordinates of the corresponding feature points of the other image.
