Automatic person identification using un-obtrusive methods are of immense importance in the area of computer vision. Anthropometric approaches are robust to external factors including environmental illumination and obstructions due to hair, spectacles, hats or any other wearable. Recently, there have been efforts made on people identification using walking pattern of the skeleton data obtained ...

Creating realistic human movement is a time consuming and labour intensive task. The major difficulty is that the user has to edit individual joints while maintaining an overall realistic and collision free posture. Previous research suggests the use of data-driven inverse kinematics, such that one can focus on the control of a few joints, while the system automatically composes a natural postu...

Background: The sternoclavicular joint (SCJ) is the only synovial articulation between the upper extremity and the trunk. This joint is one of the most frequently used joints, so osteoarthritis (OA) should be very common. However, there are few studies about OA in this joint. Methods: In this study, 48 sternoclavicular joints from the left and right joints of 23 cases and two left joints from t...

Integral joints provide a rapid, simple and mechanically strong connection between parts. Our investigation focuses on the assembly of cross-laminated wood veneer plates, where previous studies have shown that the strength of through-tenons is equivalent or superior to state-ofthe-art fasteners such as screws or nails. This mechanical behavior is highly dependent on a precise fit of the joints,...

Experimental techniques are demonstrated which generate segmented symbolic descriptions for complex objects with joints, such as a hammer or a glove. Complete "descriptions with relationship of parts at joints and descriptions of joints are presented. These techniques are elements of a larger scheme for description mechanisms for hypotheses, and for visual memory and recognition. 1. Introductio...

Human motion capture has a wide variety of applications, and in vision-based motion capture systems a major issue is the human body model and its initialization. We present a computer vision algorithm for building a human body model skeleton in an automatic way. The algorithm is based on the analysis of the human shape. We decompose the body into its main parts by computing the curvature of a B...

Markerless motion capture system and X-ray fluoroscopy as two markerless measurement systems were introduced to the application method in sports biomechanical areas. An overview of technological process, data accuracy, suggested movements, recommended body parts explained. The consists four parts: camera, model, image feature, algorithms. Even though seems promising, it is not yet known whether...

The effectiveness of transmitting force by using undulation is well known, but it takes time for the whip to flex and then sequentially transmit force. An example of using undulation is a whip whose tip movement exceeds the speed of sound. The whip-like motion principle requires that the user firmly plant the feet on the ground – a position that may lead to physical damage. Experts note that th...

In recent years, increasing automotive safety by improving crashworthiness has been a focal point in the industry, employing high-strength steel such as press hardenable (PHS). addition to improved strength of individual parts body vehicle, resistance-spot-welded joints these is highly important obtain safe structure. general, dimensions weld nuggets are regarded one criteria for quality spot-w...
