Dim and Small Target Detection Based on Gaussian Markov Random Field Motion Direction Estimation

Abstract: To improve the detection of dim and small targets in low signal-to-noise ratio (SNR<3dB) scenarios, energy accumulation along the estimated direction by estimating the direction of the target's motion at different moments is a proven approach, and considering that the Gaussian Markov random field can well describe the correlation of image element points in their air and time domains, Gaussian Markov random field is introduced into the paper to process the image. Firstly, by combining the proximity of image ele… Show more
