Abstract: An image processing apparatus acquires a plurality of input images which are serially photographed, detects a plurality of object regions from each input image, and associates object regions in a past input image with object regions in a current input image. If any object region that has not been appropriately associated exists in the object regions detected from the past input image, the apparatus calculates object region movement information for each size of the object region based on the object regions mutually associated between the past input image and the current input image, and estimates a position of the object region of the current input image that has not been associated based on the movement information for each size of the object region and a size of the object region that has not been associated.

Abstract: An image processing apparatus divides an image into a plurality of first image blocks, each of which is a partial area of the image, and further divides each first image block to acquire a plurality of compartments that correspond to filters for determining an edge direction of an image of the first image block. The image processing apparatus determines the edge direction of each first image block based on the plurality of compartments and the filters, and decides that a first image block whose edge direction cannot be determined is a failed image block. The image processing apparatus then generates, from the failed image block, a second image block constituted by a plurality of compartments that differ in size from the plurality of acquired compartments, and determines the edge direction of the second storage block based on the plurality of newly generated compartments and the filters.

Abstract: An information searching apparatus for searching for information calculates a matching degree, which indicates a degree at which searching conditions used for searching for the information are satisfied, decides a complete matching area in which is displayed information whose matching degree indicates a complete matching, and displays information on an inside or an outside of the complete matching area in accordance with whether or not the matching degree of the information indicates a complete matching.

Abstract: An information search apparatus includes query condition input means for inputting a query condition, storage means for storing a plurality of image data which undergo a search, first similarity calculation means for calculating similarity values between the query condition and the individual image data by comparing the query condition with each image data stored in the storage means, first search result display means for displaying the search results on the basis of the similarity values calculated by the first similarity calculation means, image selection means for selecting a specific image from the image data displayed as the search results by the first search result display means, second similarity calculation means for calculating the similarity values between the specific image selected by the image selection means and the plurality of image data stored in the storage means, and second search result display means for displaying the search results on the basis of the similarity values calculated by the

Abstract: There is provided an image search apparatus which can display a search result more preferably when a search is made for an image upon designation of a keyword or object, and can efficiently searches for a desired image from the displayed search result. An image feature designation unit (104) designates a feature of a search target image. A candidate image decision unit (105) searches the feature of the partial images on the basis of the designated feature of the image, and determines, as a candidate image, an image which is made to correspond to the partial image obtained on the basis of the search result. A search result display unit (106) displays enlarges the partial image included in the determined candidate image to a predetermined size and displays a reduced image of the candidate image.

Abstract: 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.

Abstract: Crude immunoglobulin G isolated from human blood plasma is treated according to a conventional technique (such as the tricalcium phosphate adsorption method) to remove aggregates therefrom to such an extent that they are not detectable by gel filtration analysis. In order to produce an aqueous solution of immunoglobulin G having a reduced anticomplementary activity, the resulting solution is then filtered through a porous polyolefin membrane having a pore size larger than the molecular size of immunoglobulin G, in the presence of a stabilizer having surface activity. The aqueous solution of immunoglobulin G so produced is suitable for use in intravenous injection because its anticomplementary activity is low.
