Two dimensional autonomous isotropic detection technique
First Claim
1. A method for detecting an object image within image data comprising:
- receiving image data;
segmenting the image data into multiple windows;
determining a likelihood that each window contains the object, and probability rank ordering the multiple windows based on the step of determining; and
selecting a predetermined one of the multiple windows as a window wherein the object image is considered to reside.

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 rom 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.

16. A target detection process comprising:
-
acquiring image data;
down-sampling the image data 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
forwarding combined results to a decision making authority.
