Region-of-Interest Detection and its Application to Image Segmentation and Compression

In many intelligence, surveillance, and reconnaissance (ISR) applications, it is desirable to detect potential targets or regions of interest (ROIs) within various types of digital imagery. These ROIs can then be used to automatically cue sensors and assets, to control intelligent region-of-interest-based image compression algorithms, and to direct further analysis for target identification and recognition. In this article, we present our hierarchical region-of-interest detection (HROID) algorithm that can quickly identify and isolate critical regions within low-quality imagery
