Abstract

The invention discloses an adaptive particle filter target tracking method based on deep learning, comprising the following steps: (1) establishing a shallow deep learning network model, and using the SGD algorithm to train the model offline; (2) applying the trained network Based on the particle filter tracking framework, for each particle, use depth features and color appearance features to solve the observation model; solve the state transition model according to the first-order and second-order motion information; (3) calculate the weight parameters of each particle according to the observation model , determine the current target position by weighted average; (4) Calculate the current state of the target, determine the degree of state change, and update the observation model in real time. The present invention provides an adaptive particle filter target tracking method based on deep learning, which can solve the problems of fast movement and complex background in existing target tracking, thereby realizing continuous and robust tracking.

Description

technical field [0001] The invention relates to the technical field of particle filter target tracking, in particular to an adaptive particle filter target tracking method based on deep learning. Background technique [0002] Video object tracking has become a cutting-edge research hotspot in the field of computer vision. Its main task is to obtain the position and motion information of the target of interest in the video sequence, and provide the basis for further semantic analysis. The research on video object tracking is widely used in intelligent video surveillance, human-computer interaction, medical diagnosis and other fields, and has strong practical value. [0003] Tracking algorithms can be divided into discriminative and generative. Discriminative methods model the tracking problem as a binary classification problem to distinguish objects from backgrounds. Generative methods search image regions with minimal reconstruction error by building object representation...
