Abstract
The present invention discloses a target detection process that acquires imagery from a target; compares the acquired imagery with image metric data; applies criteria to eliminate false detections and reduce clutter; applies morphological operators on the acquired imagery; probability rank orders the target imagery; divides the imagery into a series of detected target windows; and displays the detected target windows. The imagery undergoes light target detection, dark target detection or both. A morphological operator isolates targets from their background. Two concatenated morphological filter patterns are used to screen imagery data. Spatial discontinuities at the pixel level can be detected. The detected target window images are presented to a user in a mosaic format.
Claims7
A target detection process comprising:
- acquiring image data at a processor;
- down-sampling the image data in the processor n-times;
- processing the down-sampled image data for detecting at least one of a light target and a dark target;
- labeling subsets of the image data that may contain target data and rejecting clutter associated with these subsets of the image data;
- combining results of the image data that has been down-sampled;
- and
- extracting and rank ordering plural windows based on the combined results.
