Multidirectional Ring Top-Hat Transformation for Infrared Small Target Detection

نویسندگان

چکیده

Fast and robust detection of a small target in an infrared image is one the key techniques search track systems. The top-hat transformation important technology field detection. Many algorithms have been proposed to improve by modifying different structural elements. However, these methods can cause high false alarm rate under conditions dim targets, low signal-to-noise, complex background. To overcome this limitation, considering both performance speed, effective model using multidirectional elements article. First, nonconcentric ring are designed. Then, morphological with designed elements, background suppressed, enhanced directions. Finally, results transformations fused obtain final result, further highlighting target. experimental demonstrate method for various backgrounds targets. In addition, achieve speed up 10.4 ms per frame resolution 240 $ \times $ 320 pixels. Therefore, suitable real-time applications.

Robust Small Target Co-Detection from Airborne Infrared Image Sequences

In this paper, a novel infrared target co-detection model combining the self-correlation features of backgrounds and the commonality features of targets in the spatio-temporal domain is proposed to detect small targets in a sequence of infrared images with complex backgrounds. Firstly, a dense target extraction model based on nonlinear weights is proposed, which can better suppress background o...

Small Infrared Target Detection by Region-Adaptive Clutter Rejection for Sea-Based Infrared Search and Track

This paper presents a region-adaptive clutter rejection method for small target detection in sea-based infrared search and track. In the real world, clutter normally generates many false detections that impede the deployment of such detection systems. Incoming targets (missiles, boats, etc.) can be located in the sky, horizon and sea regions, which have different types of clutters, such as clou...
