Point target detection based on Temporal-Spatial Over-Sampling system

Fusion Detection Algorithm for Infrared Dim Target based on Temporal-Spatial Domain Accumulation and Difference

Aiming at the problem of the dim target real-time detection in Infrared search and track (IRST) systems, a fusion detection algorithm for infrared dim target based on temporal-spatial domain accumulation and difference is proposed. The proposed algorithm suppresses background and enhances targets by template filtering and difference processing in space domain, and the image sequences are proces...

Dim Target Detection System Based on DSP

The research on distributed system’s dim target detection and tracking is very important to improve the performance of infrared guard system. When the image background is very intricate, and there are few pels of targets, it is very hard to check the target. An local texture analysis method which is very fit for dim target detection in low signal to noise rate was adopted to realize the detecti...

On Point-Based Temporal Disjointness

We address the problems of determining consistency and of nding a solution for sets of 3-point relations expressing exclusion of a point from an interval, and for sets of 4-point relations expressing interval dis-jointness. Availability of these relations is an important requirement for dealing with the sorts of temporal constraints encountered in many AI applications such as plan reasoning. We...

The Performance of Small Support Spatial and Temporal Filters for Dim Point Target Detection in Infrared Image Sequences

The effectiveness of small support spatial filters based on mean, median and morphological opening for the detection of scintillating ultra-dim stationary point targets in IR image sequences has been investigated. The effectiveness of two temporal filters was also studied. The filters were applied to two IR image sequences; an aircraft approaching in an uncluttered background, and an aircraft r...
