Hockey rink registration is a useful tool for aiding and automating sports analysis. When combined with player tracking, it can provide location information of players on the rink by estimating a homography matrix that can warp broadcast video frames ...

The Universal Immunization Programme in India has a mandate to fully vaccinate all of India’s 27 million children born annually. The vaccination doses are recorded by frontline health workers on standardized paper-based Mother and Child Protection (MCP) ...

In this paper, we propose a method to quantify the spatially-varying uncertainty associated with external-camera-based pose estimates of autonomous mobile robots in an indoor setting. We build an observation model for the camera based on an estimate of ...

Developments in wearable eye tracking devices make them an attractive solution for studies of eye movements during naturalistic head/body motion. However, before these systems’ potential can be fully realized, a thorough assessment of potential sources ...

This paper discusses the development of a vision-based intra-row navigation system for an agricultural robot. The development of this system was used to reduce the effects of converging verticals distortion due to the inclined, forward facing pose and ...

Video summarisation (VS) is a technique to extract keyframes from a video based on video contents. It provides user with a brief representation of video contents to semantically understand the video. This paper aims to present video summarisation based on ...

In this paper, we propose a new video inpainting method which applies to both static or free-moving camera videos. The method can be used for object removal, error concealment, and background reconstruction applications. To limit the computational time, a ...

In this paper we present a collaborative augmented reality application for mobile users. The objective is to explore an environment by multiple users. Each user communicates information about the explored area to other users. The main idea consists of ...

Homography estimation is a fundamental problem in the field of computer vision. For estimating the homography between two images, one of the key issues is to match keypoints in the reference image to the keypoints in the moving image. To match keypoints ...

An unmanned aerial vehicle (UAV) has many applications in a variety of fields. Detection and tracking of a specific road in UAV videos play an important role in automatic UAV navigation, traffic monitoring, and ground-vehicle tracking, and also is very ...

Cycling, as a mode share of urban travel, is widely desired to be increased. To support the delivery of improved infrastructure, robust modelling is desired and modelling such agents demands real-world calibration. Data to enable this is expensive ...

Duplication of images is a common occurrence in community based data sharing systems. An image of the same scene, residing as multiple copies in the system, introduces redundancy. This paper describes a novel technique to detect such submissions by ...

In this paper, a Particle Swarm Optimization proposition is presented to solve the Homography problem. We tested our technique with several datasets. Also a comparison with existing technique (SVD) is done. PSO shows a significant superiority comparing ...

We introduce a method for replacing the background in a video of a moving foreground subject, when both the source video capturing the subject, and the target video capturing the new background scene, are natural videos, casually captured using a freely ...

Road In this paper, we focus on both the road vehicle and pedestrians detection, namely obstacle detection. At the same time, a new obstacle detection and classification technique in dynamical background is proposed. Obstacle detection is based on ...

In this paper, a novel method of the 2D Euclidean structure recovery in one view from the projections of N parallel conics is proposed. Without considering the conic dual to the absolute points (CDAP), we transform conic features from the homogeneous ...

The main idea of this paper is to use distances between camera positions to recover the trajectory of a mobile robot. We consider a mobile platform equipped with a single fixed camera using images of the floor and their associated inter-image ...

In this paper, we propose an approach for planar object recognition using binary local invariant feature and local histogram features, in scene image. First, the object is detected based on a homography which represents transformation of object in scene ...

In this paper, we propose an approach for object recognition using binary local invariant features and color information. In our approach, we use a fast detector for key point detection and binary local features descriptor for key point description. For ...

The technology of panoramic image construction is widely used in many conditions. As the increasingly demand of monitoring system application, the attribute of real-time is more important during the panoramic construction. This paper describes a method ...
