Dual-Model Detection Method of Warship Target in the Sea-Sky Background

Abstract

In order to improve the efficiency and accuracy of warship target detection in sea-sky background,and according to the obvious gray scale contrast between the sky region and the sea region, this paper operate the division of the two regional context by looking for low-water mark of the histogram's Valley, which is one feature of the histogram called "Two Peaks and a Valley". Then the method obtains the statistics and classification of background pixels, and selects the relevant parameters to establish Gaussian model A and parameter model B. Model A is used to complete the perception of invasion target and to transmit the relevant information to model B immediately,then the model B distinguishes the target with labeling. The experimental results show that the algorithm has a good ability to adapt to the environment, easy to implement and accurate at target detection.
