摘要： A plurality of feature points are extracted from an inputted image, and a feature amount is computed with regard to the feature point thus extracted. A prescribed plurality of alterations, i.e., a rotation, an enlargement, or a reduction, are applied to the inputted image, a plurality of altered feature amounts are estimated with regard to the feature point, and an image is retrieved from among stored images that are stored upon a storage apparatus and that is most similar to the inputted image, in accordance with the plurality of the estimated altered feature amounts.

摘要： A page image is acquired. Area information that includes information on existence or absence of a text area and a picture area is extracted from the acquired page image. The page image is divided into a plurality of blocks. An image feature amount of each of the divided blocks is calculated. Whether the page image includes a picture area is determined on the basis of the extracted area information and the calculated image feature amounts of the blocks.

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.
