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 · This local contrast measure based method measures the difference between the current position and its adjacent position. Then the target is separated from the background by threshold operation. Based on the accuracy and real-time of this method, a large number of methods based on HVS have emerged.
