Witryna1 cze 2024 · Local Contrast Method (LCM) [12] proposes a local contrast operator to measure the difference between each point and its neighborhood. Since LCM was proposed, many improved local contrast methods have been proposed, such as improved LCM (ILCM) [13] ... WitrynaThe SDWLCM is mainly divided into three steps: DoG filter preprocessing, generating contrast salience map, and segmenting small target. The second step is the core of the proposed method, which effectively improves the small target's SNR gain and the background suppression factor.

Witryna1 lip 2024 · The most representative work is the local contrast measure (LCM) proposed by Chen et al. , which was inspired by the biological visual mechanism. Considering that LCM has a drawback of over-enhancing bright noises, Han et al. ( 2014 ) proposed an improved local contrast measure (ILCM) to lower the false alarm rate. Witryna1 maj 2024 · The IFM aims to enhance the response of infrared small targets and suppress the response of background, which is helpful to improve the detection performance for infrared small targets. The ISTDM aims to extract the features and predict the position and category of the infrared small targets.
