Abstract
Abstract A new revolutionary approach to image processing is disclosed. The current limitations of video technology in video image analysis and processing are eliminated. A new "large format" data acquisition system is described which permits a user of the system to process analog data with any required degree of resolution. The degree of resolution obtainable is limited only by the application and source data in connection with which the system is being utilized. The preferred embodiment of the invention permits the analog data source, a map, a photograph, an x-ray, or any other two or three dimensional object or data that can be imaged on a video system, to be segmented into a series of video images which, when sequentially processed, produce an accurate mosaic of the original image. In this manner the size, the shape or image of a rock, a tree or a pond in a photograph of a one acre field can be precisely viewed, measured or outlined for whatever purpose the user of the system desires. The basic components of the system are an X-Y positioning table, a microcomputer, a video camera for acquiring the segmented images, and an ordinary TV set for use in display and analysis of the segmented images that make up the entire analog record of the original image. The possible applications of the system are virtually unlimited in the fields of agriculture, agronomy, animal husbandry, manufacturing, quality control, weather, medicine, and the like, and the possible forms of analysis are similarly unlimited in that the system can be used for analysis of area, distance measurements, density, heat characteristics or any other subject which can be electromagnetically imaged.
