Abstract

The invention discloses a multi-depth feature fusion image saliency target detection method and system. The method comprises the steps of obtaining to-be-detected image information in a set scene; inputting the image information into a trained multi-depth feature fusion neural network model; wherein the multi-depth feature fusion neural network model adopts convolution to perform feature extraction in a coding stage, restores information of an input image in combination with an up-sampling method of convolution and bilinear interpolation in a decoding stage, and outputs a feature map with significance information; learning feature maps of different levels by adopting a multi-level network, and fusing the feature maps of different levels; and outputting a final saliency target detection result. According to the invention, a multi-depth feature fusion neural network is used to carry out saliency target detection on an image in a scene, the detection precision is guaranteed, and the speedof a subsequent processing process is accelerated; a contour detection branch is added, and the boundary details of the to-be-detected target by using contour features are refined.

Description

Technical field[0001]The present invention relates to the technical field of image saliency target detection, in particular to a method and system for image saliency target detection based on multi-depth feature fusion.Background technique[0002]The statements in this section merely provide background information related to the present invention, and do not necessarily constitute prior art.[0003]Saliency target detection refers to the use of computers to imitate the human visual attention mechanism to separate the people or things in the image that can most attract human visual attention from the background. An image is composed of many pixels. The brightness, color and other attributes of the pixels are different, and their corresponding salient feature values ​​will also be different. Different from traditional object detection and semantic segmentation tasks, salient object detection only focuses on the part that can attract visual attention without classifying it, and the general...
