Abstract

A method for detecting a salient object in dynamic scene is disclosed. That salient object detection in dynamic scene is a salient detection process by analyzing the moving state of the object in moving video. The method mainly includes three steps: firstly, moving object detection is carried out in the dynamic scene, and all moving object regions in the scene are obtained; then, image features are extracted from dynamic scene and fused at feature level to get image fusion feature vector, which is used to detect visual fixation point based on Bayesian inference; finally, combined with fixationdetection, the saliency of the detected moving object is estimated, and a dynamic saliency map based on the moving object is generated. The invention solves the problem of salient object detection ofthe camera under the moving condition, can meet the requirement of the machine vision system for detecting the salient object in the dynamic scene, and the method has strong adaptability to the environment change.

Description

technical field [0001] The invention belongs to the field of digital image processing, and in particular relates to a method for detecting a salient target in a dynamic scene. Background technique [0002] In the field of life sciences, research on the human visual system has found that humans have the ability to selectively focus on key information from complex scenes, which can help humans quickly and accurately process information and make judgments. The selective mechanism of the human visual system is defined as the visual attention mechanism, and the basis that can support the visual attention mechanism to select information in the scene is defined as visual saliency; researchers in the field of machine vision believe that visual saliency detection It can help improve the ability to quickly process massive and complex information. According to this, the research on saliency detection based on digital image can be sprouted and developed. [0003] At present, the resea...
