Object Tracking through a Hough Space
نویسندگان
چکیده
A visual tracking method is introduced which performs no direct tracking of any feature in the image plane. Instead, images are transformed using a variant of the Hough technique and features are tracked by the parameters which describe them. This enables features to be combined and constrained by their structure, allowing tracking of more complex shapes with a controlled degree of flexibility and distortion. Results are presented tracking rectangular structures in a variety of image sequences.

Object Tracking via the Dynamic Velocity Hough Transform
Motion tracking is an important task in computer vision. A new technique, the dynamic velocity Hough transform (DVHT), for tracking of parametric objects is described that extends the velocity Hough transform (VHT) to cater for arbitrary motion. Like the VHT, the new technique processes the whole image sequence, gathering global evidence of motion and structure. However, we do not assume consta...
متن کاملConvex Hulls, Occluding Contours, Aspect Graphs and the Hough Transform
The Hough transform is a standard technique for finding features such as lines in images. Typically edgels or other features are mapped into a partitioned parameter or Hough space as individual votes. The target image features are detected as peaks in the Hough space. In this paper we consider not just the peaks but the mapping of the entire shape boundary from image space to the Hough paramete...
متن کاملConvolutional Gating Network for Object Tracking
Object tracking through multiple cameras is a popular research topic in security and surveillance systems especially when human objects are the target. However, occlusion is one of the challenging problems for the tracking process. This paper proposes a multiple-camera-based cooperative tracking method to overcome the occlusion problem. The paper presents a new model for combining convolutiona...
متن کاملRobust mobile robot localisation from sparse and noisy proximity readings using Hough transform and probability grids
We present a robust position tracking method for a mobile robot with seven sonar sensors. The method is based on Hough transform and probability grids. The focus of the paper is on the problem how to handle sparse sensors and noisy data in order to develop a low-cost navigation system for real-world applications. The proposed method consists of three steps. It computes a two-dimensional feature...
متن کاملFast Detection of Gpr Objects with Cross Correlation and Hough Transform
Abstract—A GPR object detection algorithm delivers a promising performance using the Hough transform through a high computational load. This paper presents a fast Hough-based algorithm. To reduce the parameter space of the Hough transform, first, two parameters for a reflection hyperbola were estimated using cross correlation between adjacent A-scans. Next, only a 1D Hough transform is necessar...
