Visual target tracking method based on deep residual network characteristics

Abstract

The invention discloses a visual target tracking method based on deep residual network characteristics. The visual target tracking method comprises the following steps: 1, selecting a characteristic layer of a deep residual network and calculating a weight; 2, extracting features of the first frame of actual input image; 3, constructing a response and initial position filter of the characteristicsof the first frame of actual input image; 4, performing scale sampling and fHOG feature extraction on the first frame of actual input image; 5, constructing an initial scale filter; 6, feature extraction of the second frame of actual input image; 7, position filtering; 8, weighting a position filtering response graph and positioning a target; 9, performing scale sampling and fHOG feature extraction on the target image; 10, performing scale filtering and scale estimation on the target feature vector; 11, updating the filter; And 12, inputting a next frame of actual input image, regarding the next frame of actual input image as a second frame of actual input image, and repeating the step 6. The method is high in tracking precision and success rate, adapts to target scale changes, and achieves the robust tracking of the target.

Description

technical field [0001] The invention belongs to the technical field of target tracking, and in particular relates to a visual target tracking method based on deep residual network features. Background technique [0002] The application of artificial intelligence is very extensive, covering many technical fields, mainly including computer vision, natural language processing, cognition and reasoning, robotics, game and ethics, machine learning, etc. Vision is the most important source of information for the human brain, and it is also the door to enter the palace of artificial intelligence. About 70% of human cerebral cortex activity is processing visual related information. Computer vision uses images (videos) as input to study image information organization, object and scene recognition, etc., and then explain events, so as to realize the expression and understanding of the environment. [0003] As one of the basic problems in the field of computer vision, object tracking ...

Problems solved by technology

The discriminative model algorithm trains a classifier to distinguish the target from the background, and selects the candidate sample with the highest confidence as the prediction result. Due to the limitation of the accuracy and speed of the tracking algorithm, the application of the tracking algorithm in the actual scene is still restricted.
