A detection algorithm, based on the combined local-global (CLG) optical-flow model and Gaussianpyramid for a moving target appearing against a dynamic background, can compensate for the inadaptabilityof the classic Horn–Schunck algorithm to illumination changes and reduce the number of neededcalculations. Incorporating the hypothesis of gradient conservation into the traditional CLG optical-flowmodel and combining structure and texture decomposition enable this algorithm to minimize the impactof illumination changes on optical-flow estimates. Further, calculating optical-flow with the Gaussianpyramid by layers and computing optical-flow at other points using an optical-flow iterative with highergray-level points together reduce the number of calculations required to improve detection efficiency.
Finally, this proposed method achieves the detection of a moving target against a dynamic background,according to the background motion vector determined by the displacement and magnitude of theoptical-flow. Simulation results indicate that this algorithm, in comparison to the traditional Horn-Schunckoptical-flow algorithm, accurately detects a moving target undergoing illumination changes against adynamic background and simultaneously demonstrates a significant reduction in the number of computationsneeded to improve detection efficiency.
