Abstract
A system and method for processing video imagery. The system automatically selects for transmission, or storage, portions of a video image at an automatically selected compression level, and/or in an automatically selected order. The system and method are intended to supplement and/or replace human actions with autonomous operations that are intended to preserve and prioritize important image information and highly reduce or eliminate image data that does not contain significant information. The preservation of important and relevant image information is given a higher priority than preservation of overall image quality.
Claims16
A method of processing digital data representative of a video image comprising the steps of:
- (a) dividing the data into a plurality of blocks representing a region of the video image;
- (b) automatically evaluating a predetermined characteristic of the data in each block to provide a processing signal indicative of the evaluated characteristic for each block;
- (c) displaying the video image on a monitor;
- (d) indicating the processing signal for each block on the monitor;
- (e) selectively manually overriding the processing signal;
- and
- (f) processing the data in accordance with the automatically provided processing signals as manually overridden.
A method of automatically determining the degree of reduction of the amount of data representative of a video image comprising the steps of:
- (a) dividing data representative of a video image into a plurality of blocks representing a region of the video image;
- (b) providing a neural net;
- (c) training said neural net by operator evaluation of a plurality of subject matter related subimages both as to region and significance of the data within the region;
- (d) determining the significance of the data in each of said blocks by reference to the neural net;
- and
- (e) compressing the data in each of said blocks to a degree related to the determined significance.
A system for processing blocks of digital data representative of regions of a video image comprising:
- automatic means for evaluating a predetermined characteristic of the data in each block to provide a processing signal indicative of the evaluated characteristic for each block;
- a monitor for displaying the video image;
- means for indicating the processing signal for each block on the monitor;
- manual selection means for selectively overriding the processing signal;
- and
- processing means for processing the data in accordance with the automatically provided processing signals as manually overridden.
A system for automatically determining the degree of reduction of the amount of data in a plurality of blocks, each representative of a portion of a video image comprising:
- a neural net for evaluating a plurality of subject matter related subimages in the video image;
- means for determining the significance of the data in each of said blocks by reference to the neural net;
- and
- means for compressing the data in each of said blocks to a degree related to the determined significance.
