We propose an IR small target detection method using our new homogeneity-weighted local contrast measure (HWLCM). Inspired by the ability of the human visual system (HVS) to determine saliency characteristics, we implement our method to use the local contrast features of the central and ...
The mean value of cell elements in the central area is mT, and the mean value of cell elements in the four directions around the central area is respectively mBi ði ¼ 1, 2, 3, 4Þ: We design the local contrast meas urement (LCM) between the center cell as in (5). d...
By contrast, the multiplication involved in LCM is usually related to the similarity matrix and a few of instances supporting the discriminate boundary in the case of SVM. Consequently, LCM only depends on the positive instances and the negative instances, of which both are located on the ...
2020). In contrast, mangroves on the islands of the Dampier Archipelago tend to be relatively small, fringing stands, some of which are only inundated for short periods during the day (Semeniuk and Wurm 1987). As such, larger tidal ranges may reduce the value of intertidal mangrove habitat f...
The LCM reveals preference heterogeneity between the probability of being a member of Class 1 (45%) or Class 2 (55%). As explained in the methods section, each latent class is inferred from the levels of the attributes through multinomial logistic regression. Class 1 has increasing negative ...
In this paper, in order to improve the traditional local contrast method and detect small targets effectively under complex background conditions, a novel method base on Facet-kernel filtering local contrast measure (FFLCM) is proposed for small target detection. Initially, a nest sliding window ...
A tri-layer window in time domain is proposed, and a multiscale temporal relative local contrast measure (TRLCM) is developed to detect infrared (IR) small moving targets. The proposed algorithm divided some consecutive frames into five parts: the peak, the two guards, and the two baselines....
(IRST) systems, in this paper, inspired by the mechanism of the human visual system (HVS), we present a robust algorithm for the detection of infrared (IR) dim and small targets based on Multi-scale Local Contrast Measure utilizing Efficient Spatial Filters, which is named as ESFMLCM. In...
To solve this problem, we propose a weighted improved double local contrast measure (WIDLCM) algorithm in this paper. Firstly, we utilize a fixed-scale three-layer window to compute the double neighborhood gray difference to screen candidate target pixels and estimate the target size. Then, ...
Inspired by HVS, several approaches based on local contrast, such as local contrast measure (LCM) [34], Laplacian of Gaussian (LoG) filter [33], high-boost multi-scale local contrast measure (HBMLCM) [35], multi-scale patch contrast measure (MPCM) [10], homogeneity-weighted local contrast...
