Real-Time Object Tracking via Adaptive Correlation Filters

Abstract

Although correlation filter-based trackers (CFTs) have made great achievements on both robustness and accuracy, the performance of trackers can still be improved, because most of the existing trackers use either a sole filter template or fixed features fusion weight to represent a target. Herein, a real-time dual-template CFT for various challenge scenarios is proposed in this work. First, the color histograms, histogram of oriented gradient (HOG), and color naming (CN) features are extracted from the target image patch. Then, the dual-template is utilized based on the target response confidence. Meanwhile, in order to solve the various appearance variations in complicated challenge scenarios, the schemes of discriminative appearance model, multi-peaks target re-detection, and scale adaptive are integrated into the proposed tracker. Furthermore, the problem that the filter model may drift or even corrupt is solved by using high confidence template updating technique. In the experiment, 27 existing competitors, including 16 handcrafted features-based trackers (HFTs) and 11 deep features-based trackers (DFTs), are introduced for the comprehensive contrastive analysis on four benchmark databases. The experimental results demonstrate that the proposed tracker performs favorably against state-of-the-art HFTs and is comparable with the DFTs.

Analysis of People Flow Image Detection System Based on Computer Vision Sensor

“…The preprocessing of the image can effectively suppress the noise of the image; the process of image preprocessing is to read each frame of image captured by the camera, then grayscale the image, and filter the final grayscale image. Image preprocessing is to filter the edge information of the image to make the image easier to detect, that is, image filtering [15][16][17].…”

Methodological Insights Towards Leveraging Performance in Video Object Tracking and Detection

“…The study also addresses the problems associated with ambient noise using channel and spatial attention. Another study of real-time object tracking is carried out by Du et al [70] that addresses the problems associated with implementing Correlation Filter-based Trackers (CFT) on www.ijacsa.thesai.org practical grounds. In this mechanism, feature extraction is carried out using Histogram of oriented Gradient (HoG) followed by integration of scale adaptive, target re-detection, and discriminative appearance model.…”
