Embodiment approach

[0044] A preferred embodiment of the video-based salient target detection method of the present invention specifically includes the following steps:

[0045] Step 1: Perform superpixel segmentation on the picture, and use the optical flow information and color information to obtain the preliminary salient target detection area.

[0046] 1. Superpixel segmentation

[0047] First, perform superpixel segmentation on video frame images. A superpixel is a small area composed of a series of adjacent pixels with similar characteristics such as color, brightness, and texture. Most of these small areas retain effective information for further image segmentation, and generally do not destroy the boundary information of objects in the image. The invention utilizes a simple linear iterative clustering method to perform superpixel segmentation. Compared with the traditional superpixel segmentation method, this method has the advantages of fast speed and good effect. This method applies...

Abstract

The invention discloses a salient object detection method based on video. The method comprises the following steps: performing super-pixel segmentation on a picture, and utilizing optical flow information and color information to obtain a preliminary salient object detection area; acquiring picture background information by using gradient information; fusing the preliminary object detection area and pruning the background to obtain a final salient object zone. According to the method, the similarity of pixels is detected by combining statistical motion information (i.e. the optical flow information) and static information (i.e. the color and gradient information) on the pixel level, foreground and background cues are fused in the result, and the purpose of detecting a salient object in video is finally fulfilled.

Description

technical field [0001] The invention relates to a video-based salient target detection method, in particular to a video salient target detection method based on foreground detection and background subtraction, and belongs to the technical field of image processing. Background technique [0002] Salient object detection is very important in the field of computer vision. Due to security needs, people pay more and more attention to the safety detection in video. In videos, it becomes especially important to detect salient objects to obtain information that people are interested in. In a video surveillance system, a salient target is an object that attracts people's attention at the first sight in the picture. Salient object detection is to find such objects in pictures or videos through algorithms to replace human visual functions, so as to prepare for subsequent higher-level video detection work. [0003] In recent years, many saliency detection methods focus on detecting f...
