A microfiche retrieval scheme having input means for introduction of index information indicative of desired subjects for retrieval, store means which provide pieces of frame address information for one or more microimages concerning the desired subjects in response to the index information and an optical system for projecting the selected microimages onto a viewing screen in accordance with the thus delivered frame address information. The above scheme further comprises a printer adapted to print out information contained on the microimages selected and transmitted to the optical system, a print control adapted to control the microfiche retrieval scheme and the printer and means for providing for the print control a signal indicating the printing out of the information of the selected microimages or that of their next succeeding microimages.

In an improved system for loading new microfiches, or updating previously stored microfiches, in a microfilm cassette library; a registration mode is provided whereby a keyboard operator can register keyword a and other index information for specific frames while these microimages are concurrently being projected on a viewing screen. Structures are included for receivingand holding fiches or cassettes being registered, for positioning frames for optical projection, and for reading magnetically encoded fiche identity data. Both buffer memory and file memory means are provided for storage of frame address information including cartridge identity, microfiche identity, X and Y axes coordinates, and other index data. Microcomputer means are provided for overall control of the registration of new fiches and for retrieval of same.

A color image input from a document image inputting unit is converted into a gray-scale image by a brightness image extracting unit. The gray-scale image is then converted into an image having a higher resolution according to the resolution of the original gray-scale image. When this conversion is performed, subpixels are generated between the original pixels, and the values of the subpixels are obtained with an interpolation method. Furthermore, a threshold value for a binarization process is generated by using an original pixel value and a subpixel value. The characters included in the binarized image are recognized by a binary image recognizing unit, and a recognition result is output from a recognition result outputting unit.

A document image tilt detection unit extracts a set of elements forming a character from a document image, extracts candidates for horizontal and vertical lines based on the character elements, estimates the reliability of each candidate for a line, and extracts a set of probable lines. Then, it estimates the tilt of the document image based on the arrangement of the character elements belonging to the line elements in the set of probable lines. A layout analysis unit extracts a set of lines in a fixed line direction from a set of basic elements forming the document image, and reciprocally performs the extraction of a column based on the correlation between lines and the extraction of a line based on the restrictions of the column. By providing the document image tilt detection unit and the layout analysis unit, the tilt of the document image containing both vertical and horizontal character lines can be detected, and lines and columns can be extracted at a high speed with high precision.
摘要:
A moving body recognition apparatus which recognizes a shape and movement of an object moving in relation to an image input unit by extracting feature points, e.g. a peak of the object and a boundary of color, each in said images captured at a plurality of instants in time for observation by the image input unit. The moving body recognition apparatus comprises an image input unit for capturing images of an object as a moving body having a rotation, a feature point extraction unit for extracting feature points from the images inputted by the image input unit, a feature point storage unit for storing known position data of the extracted feature points, and a shape/movement recognition unit for calculating the actual positions and movements of the feature points of the object in the images by using the known position data of the extracted feature points outputted from the feature point storage unit.
摘要:
A computer graphics data display device and method simplify a movement interference calculation by use of an interference attribute of an object, and control a process time by predicting a display time of a frame. Furthermore, the number of simultaneously calculated moving objects is restricted to speed up the calculation, and a retrieving process can also be performed at a high speed using display data obtained by compressing editing data. If any change has arisen in the editing data, only change data are transmitted to a display data memory unit, and the editing data and the display data are concurrently processed. Thus, dynamic images can be successfully displayed with reality.
