Image data processing method for selective partial image display

Abstract: A retrieved image display method in an image file system in which image data records undergone a data compression and index records including positional information of the image data records are stored in a file medium. The method includes a first step to specify a partial region of a retrieved image to be displayed on a display screen, a second step to attain, based on positional information above included in an index record corresponding to the retrieved image, a recording position of an image date portion on the file medium corresponding to the partial region to be displayed and to partially read out image data from the image data record, and a third step to restore the compressed image data thus read out into the original image data and to display the restored image data on the display screen. In accordance with to the partial region specified in the first step, the operations of the second step and the third step are successively and repetitiously achieved for a plurality of retrieved images to thereby flip pages of the retrieved images on the display screen.

Abstract: PURPOSE:To execute the printing processing of the optional image reserved at the picture buffer at a high speed by executing simultaneously and in parallel the extending processing of the picture information reserved at the picture buffer having the capacity larger than the output screen of the terminal device of the terminal control device and the printing processing. CONSTITUTION:Plural pages of the picture data of the image system equivalent to retrieving conditions designated from an input device 29 of a picture retrieving terminal 2 are earlier read including the designated page from an optical disk driving unit 16 of a scanning filing device 1, and filed through a communicating line LAN 4 to an image file 31.

Stereoscopic image processing system

Abstract: PURPOSE:To obtain highly accurate distance information or height information by estimating and correcting geometrical distortion on an image which may be generated due to the difference of a visual point on the basis of the relation of stereoscopic corresponding points found on an image with low resolution due to gradual thinning. CONSTITUTION:A pair of stereoscopic image data 1 is thinned to 1/2 the quantity of data by an image blurring thinning processor 2. Since simple image thinning does not satisfy a sampling theorem, blurring processing is adopted. The image with 1/2 size obtained by the processor 2 is stored in an image file 3 together with the original image. The image with 1/2 size stored in the image file 3 is read out again and furthermore blurred and thinned by the processor 2 and the blurred and thinned image is stored in the file 3 as an image with 1/4 size of the original image. After repeating image blurring thinning plural times, reduced images having plural levels are stored in the file 3. Thus, the specially rough stereoscopic corresponding relation is expressed as stereoscopic corresponding relation on the image with the current resolution.

Computer Generated Hologram and Magneto-Optic Spatial Light Modulator for Optical Pattern Recognition.

Abstract: : This thesis investigates the integration of an optical system for real-time position, scale, and rotation invariant pattern recognition. Specifically a Litton Magneto-Optic Spatial Light Modulator is interfaced to a Zenith 248 microcomputer and AT&T frame grabber. A user interfaces written in C allowed arbitrary patterns to be written to the SLM by a user. Patterns can be generated in computer code, transferred form a CCD camera (via the frame grabber), taken from an image file on computer disk, or taken from a VAX image file. The ability to locally generate a computer generated hologram using the computer generated interferogram method on the Sun workstations and Imagen laser printer was developed. The CGH developed was used in an optical coordinate transformation to create a position, scale, and rotation invariant feature space. CCD cameras were used throughout the optical processor for display/analysis. The entire system was developed and tested using various templates and real scenes.
