Image file storage and retrieval system

Abstract: A system which creates, stores, retrieves and displays thumbnail images. The dominant colors of the image are displayed in the thumbnail images. The dominant colors in an image are determined using groups of pixels where the average color is used to select an appropriate dominant color for display. The size of the thumbnails displayed and the area set for displaying the thumbnails can be changed to allow visual review of either a large number of thumbnails or a smaller but larger size set of thumbnails. Thumbnails, and other image files and other related text files and non-related files can be indexed and searched using keywords by using keyword views into the stored files to indicate a match when the views designate the same file. The system allows a search to be based on a partial match of keywords. Searching can be performed using super-keywords, which are combinations of keywords and other file and data characteristics. Super-keywords can be combined with other super-keyword or keywords for searching purposes. To facilitate multi-media storage and searching and integration of off-line media into the system, the system includes a master directory having a full directory containing entries of each media as a branch of the master directory tree. The system also includes the utilities necessary to create, access, retrieve and update local and network accessed remote files on any type of media.

Displaying radiologic images on personal computers: practical applications and uses.

Abstract: This is the fifth and final article in our series for radiologists and imaging scientists on displaying, manipulating, and analyzing radiologic images on personal computers (PCs). There are many methods of transferring radiologic images into a PC, including transfer over a network, transfer from an imaging modality storage archive, using a frame grabber in the image display console, and digitizing a radiograph or 35-mm slide. Depending on the transfer method, the image file may be an extended gray-scale contrast, 16-bit raster file or an 8-bit PC graphics file. On the PC, the image can be viewed, analyzed, enhanced, and annotated. Some specific uses and applications include making 35-mm slides, printing images for publication, making posters and handouts, facsimile (fax) transmission to referring clinicians, converting radiologic images into medical illustrations, creating a digital teaching file, and using a network to disseminate teaching material. We are distributing a 16-bit image display and analysis program for Macintosh computers, Dr Razz, taht illustrates many of the principles discussed in this review series.

Method and system for establishing communication by utilizing data, which can be visually recognized in broadcast video signal

Abstract: PURPOSE: To provide a method and system which acquire and process the visually recognizable data including the addresses and telephone numbers, etc., contained in the broadcast video signals. CONSTITUTION: A video display area 24 includes plural texts such as a telephone number 26 shown in the Arabic numerals, a graphic bar code 28, etc., or the numeric information. When a digitizer 20 receives a start command from a remote control device 30, the digital information showing such a video frame that is shown on a digital display 24 is connected to a data processing system 34 via a cable 32. The broadcast video signals are received and digitized and then stored as a tag image format in response to a user start command. A bar code reader or the optical character recognition processing is used to extract the texts and numeric character data out of the acquired video frame, and the extracted data are stored for the future use. A communication device like a modem is used to automatically establish the communication with an external location by producing a tone which is related with the acquired telephone number.

Image acquisition of microscopic slides

Abstract: This paper addresses the color medical imaging system (CMIS) program, which entails the development of a prototype system to evaluate spatial correlation techniques to convert microscopic images into full color digital electronic files. Program objectives were directed toward the creation of high resolution 2D images using spatial template matching. Full color image segments were captured using NTSC CCD array cameras. These lower resolution segments were captured in an overlapping coverage and combined at their borders as complete seamless high resolution files. The use of segmented capture overcomes the resolution limitation of the capture system, and expands the field of view of the microscope for a fixed magnification. CMIS was used to capture image segments from medical glass slide specimens using a light microscope, and to convert these segments into full color electronic image files. This paper describes the CMIS system and its image capture and conversion process.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.

Image-information format control device for controlling transmission of varied formats of image data stored in a single format

Abstract: Communication between an image-information storage device and a terminal is made possible even in a case where they have images of different image formats. An image data delivery request, transmitted from any of a plurality of terminals and received by a receiving portion, includes information indicating that the terminal has a source format of CIF or QCIF. This information is transferred to a communication control portion which informs the source format control portion of the source format (CIF or QCIF of) the terminal. When the terminal has the CIF source format, the required data transmitted from an image-information storage device are transmitted through a transmitter portion to the terminal. When the terminal has the QCIF source format, a part of the image data transferred from the image-information storage device is extracted and converted into data of QCIF format by the source format control portion. The converted data of QCIF source format are then transmitted through a transmitting portion to the terminal.

Filing system with multiple forms of storage

Abstract: There is a composite image filing system in which optical discs and microfilms are organically combined and integrally managed. This system comprises optical discs and microfilms in which image files are recorded and a work station to register, search, and process the image files. The work station has a memory to store search information of a format integrated between the optical disc and the microfilm. The search information which specifies the image files includes information indicative of the kind of medium (microfilm and optical disc), information to specify the medium number of the optical disc and the physical address in the optical disc in the case of a optical disc file or to specify the cartridge number and frame number in the case of a microfilm file, and the file name. The work station manages the image files by the search information and controls the optical disc so as to back up the search information corresponding to the image files recorded in the optical discs. Since the search information of the image files is stored into a backup dedicated memory such as optical disc or floppy disc nearest to the operation unit, the security of the search information is assured and the search information can be easily managed and reconstructed from the backup dedicated memory.
