ABSTRACT:
A method and apparatus for dynamic image processing in which an image is compressed and subsequently expanded or synthesized into an image for display, wherein the image processing is carried out by considering the image information as distributed in a three-dimensional space composed of the two-dimensional image plane and a time axis defined by the time of each of successive video image frames of the input video signal. A multiple resolution filter is employed that has different resolutions provided by increased orders of differentiation and two-dimensional image data is analyzed as it is distributed along the time axis. Signal compression is provided by coding the positional information of the edge points of the image and this is accomplished by detecting characteristic points corresponding to extreme values of the three-dimensional image information and then compressing the image information on the two-dimensional plane to obtain compressed positional information and also compressing the three-dimensional information and then coding both of these compressed information signals for transmission or recording.
