This work presents a parts-based person detection framework. The individual body segmentslegs, torsos, and heads are detected by Adaboost classifiers, which have proven useful other classification tasks [12] [6] [1] [13]. The body segment candidates are combined into kinematically plausible configurations and each is assigned a score. The body configurations are calculated using an efficient dy...

Localization of chess-board vertices is a common task in computer vision, underpinning many applications, but relatively little work focusses on designing a specific feature detector that is fast, accurate and robust. In this paper the “Chess-board Extraction by Subtraction and Summation” (ChESS) feature detector, designed to exclusively respond to chess-board vertices, is presented. The method...

Background: Carpet weaving is an occupation that requires sufficient and appropriate lighting. The lighting in carpet weaving workshops affects the productivity and the physical and mental health of workers. Therefore, the evaluation of the illumination and the identification of work stations requiring lighting modifications will be helpful in promotion of the health and safety of workers in ca...

In this work, we propose a robust visual odometry system for RGBD sensors. The core of our method is a combination of edge images and depth maps for joint camera pose estimation. Edges are more stable under varying lighting conditions than raw intensity values and depth maps further add stability in poorly textured environments. This leads to higher accuracy and robustness in scenes, where feat...

Human gesture recognition is a non-verbal part for interaction or movement that can be used to involves real world and virtual world. In this paper, we explain a study on natural user interface (NUI) in human gesture recognition using RGB color information and depth information by Kinect camera from Microsoft Corporation. To achieve the goal, hand tracking and gesture recognition have no major ...

This paper discusses a computer vision based approach for enhancing a common device (display) with machine perception capabilities. Using techniques for assessing the distance and orientation of a target from the camera, a “smart device” becomes aware about user’s presence and his interaction intentions. In other words, the “smart device” is aware when it becomes the user’s focus of attention a...

In this paper, we explain a study on natural user interface (NUI) in human gesture recognition using RGB color information and depth information by Kinect camera from Microsoft Corporation. To achieve the goal, hand tracking and gesture recognition have no major dependencies of the work environment, lighting or users’ skin color, libraries of particular use for natural interaction and Kinect de...

A hybrid real-time face tracker based on both sound and visual cues is presented. Initial talker locations are estimated acoustically from microphone array data while precise local-ization and tracking are derived from image information. A computationally eecient algorithm for face detection via motion analysis is employed to track individual faces at rates up to 30 frames per second. The syste...
