Understanding the dynamics of human walking is a complex task due to the interaction of the musculoskeletal and the central nervous systems. Nevertheless, the use of simple models can provide useful insight into the mechanical aspects of bipedal locomotion. Such models exploit the observations that human walking significantly relies on passive dynamics and inverted pendulum-like behaviour. The ...

I investigate a new approach for determining the pre-warp homography required to correct a projector image for perspective when projecting on a single flat surface. By using a depth camera placed at a fixed transform near the projector, the normal of the surface can be predicted in real time. By updating a homography on the image to be projected based on the projector intrinsics and the surface...

While quantum weight enumerators establish some of the best upper bounds on minimum distance error-correcting codes, these are not optimized to quantify performance codes under effect arbitrary channels that describe bespoke noise models. Herein, for any Kraus decomposition given channel, we introduce corresponding naturally generalize Shor-Laflamme enumerators. We an indirect linear relationsh...

The primary objective of this article is to explain about touch projector technology concept and how to use it. This paper intention is to look at the present touch projector as a new technology aimed to enable performing tasks as a huge touch screen. This paper briefs on the historical background and provide review of three recent devices which are Touch Pico, Cicret Bracelet and Dell Interact...

This research presents a novel method to calibrate a microscopic structured light system using a camera with a telecentric lens. The pin-hole projector calibration follows the standard pin-hole camera calibration procedures. With the calibrated projector, the 3D coordinates of those feature points used for projector calibration are then estimated through iterative Levenberg-Marquardt optimizati...

This paper provides a classification of calibration methods for cameras and projectors. From basic homography to complex geometric calibration methods, this paper aims at simplifying the choice of the methods to perform a calibration regarding the complexity of the setup. The classical camera calibration methods are presented. A comparison gives the pros and cons for each method. For the projec...

Projector-based embedding has recently emerged as a robust multiscale method for the calculation of various electronic molecular properties. We present the coupling of projector embedding with quantum mechanics/molecular mechanics modeling and apply it for the first time to an enzyme-catalyzed reaction. Using projector-based embedding, we combine coupled-cluster theory, density-functional theor...

In this paper we present a new approach for cooperation between mobile smart objects and projector-camera systems to enable augmentation of the surface of objects with interactive projected displays. We investigate how a smart object’s capability for self description and sensing can be used in cooperation with the vision capability of projector-camera systems to help locate, track and display i...
