TLDR
In this paper, an approach is described for detecting and classifying tactical targets in FLIR imagery, where the basic assumption used for segmenting objects from their background is that the objects to be detected differ from the background in grey level, edge, properties or texture.Abstract:
An approach is described for detecting and classifying tactical targets in FLIR imagery. The basic assumption used for segmenting objects from their background is that the objects to be detected differ from the background in grey level, edge, properties, or texture. Potential targets are selected from a large frame, by locating combinations of grey level, edge, value, and texture that occur infrequently over the entire frame. Once potential objects are obtained, they are segmented from their backgrounds using the identical process as above, except applied on a local level. The segmented objects are classified into three, types of vehicles or into false, alarms. The classification procedure uses features measured on projections made through the segmented objects. Results are shown for 32 test images.© (1979) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.read more

Object detection based on gray level cooccurrence
TL;DR: A measurement selection algorithm was formulated which shows detection accuracies of better than 90% on a number of experiments and assumes that measures computed from regions containing the object form a cluster defined by N (μ 0 , Σ 0 ) in measurement space, while measures compute from regions notcontaining the object lie some distance away from this cluster.

Comparison of segmentation processes for object acquisition in infrared images
TL;DR: A qualitative comparison of the performance of nine different segmentation algorithms on a data base of infrared images of vehicles is described, with the Bayesian technique being less favoured owing to the higher computational burden.

Video Data Conversion and Real-Time Tracking
TL;DR: The RTV system described here is an example of a new generation of real-time trackers that combines pattern recognition and image processing into a single system that automates the very labor-intensive and therefore time-heavy process of building and maintaining a tracking system.
