Infrared small target detection with compressive measurements
2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016A novel scheme for infrared small target detection in compressive domain is presented. First, the original image is separated into two components, i.e., the target and the background. Next, we compress them individually. Finally, the compressed target image is utilized to construct the corresponding compressive detector to perform detection in ...

Principal curvature for infrared small target detection
Infrared Physics & Technology, 2015Abstract Small target detection in infrared image with complex background and low signal–noise ratio is an important and difficult task in the infrared target tracking system. In this paper, a principal curvature-based method is proposed. The principal curvatures of target pixels are negative and their absolute values are larger than that of ...

Small infrared target detection using sparse ring representation
IEEE Aerospace and Electronic Systems Magazine, 2012A new approach, SRR, for small infrared target detection in single image is described herein. SRR is based on local self-similarity descriptor, according to the characteristics of small infrared targets. Using the SRR, the certainty of small targets can be easily measured.

An Efficient Algorithm for Infrared Small Target Detection
2009 Second International Conference on Information and Computing Science, 2009An improved efficient fractal algorithm, based on higher-order statistics (HOS), is presented for infrared (IR) small target detection under complex background of a single image. This algorithm is divided into two parts: coarse location and fine location.

Multiscale facet model for infrared small target detection
Infrared Physics & Technology, 2014In this paper, we proposed a new robust infrared small target detector that is more suitable for complex background with low signal-to-clutter ratio. The original image is decomposed into sub-bands in different orientations by using the directional second-order directional derivative (DSODD) filters deduced from the facet model.
