A method is presented for approximating a curved surface by developable rigid origami; polyhedral shape which can be developed to plane without deformation of its facets. Form generation starts from triangulated surface, and an optimization problem solved obtain polyhedron satisfies the geometric conditions developability. The degrees freedom origami mechanism with only triangular facets are of...

A model for tracking articulated objects is proposed using a novel 2D revolute-prismatic joint. An extension of the RANSAC and MLESAC algorithms incorporating feature weights is used to perform robust tracking. The models are suitable for tracking certain human body structures. Limbs are modelled as constrained planar patches. A patch can rotate about a joint point that is displaced relative to...

Since the entire world is covered with computerized digital data, information through media not difficult to move, access, and recycle. Currently, advanced image processing tools are used create tempered pictures. Using these apparatuses, falsifiers presented forged pictures spread gossip rumors. Presently, it quite for scientific divisions demonstrate reality of original picture. Consequently,...

Computed ultrasound tomograms of infant and adult human cadaver heads are presented and compared to x-ray CT scans obtained in the same horizontal planes. The images were reconstructed from broadband pulsed transmission data obtained using the rotate-translate scan mode. A formalin-fixed infant cadaver head was scanned using a 5 MHz center frequency yielding a transkull attenuation reconstructi...

This paper researches the design and control method of a microrobot in a microfluidic system by electromagnetic field. The microrobot can move along the microchannel to a required position, and by changing the magnetic torque, the microrobot can also rotate in the microfluidic chip. As an application of the microrobot, it is used as a mobile micromixer to mix two solutions in the microfluidic c...

with increasing use of robots instead of human in industrial, medicine and military applications etc.the importance of research on designing and building of robots is increasing. in this paper variousmethods of the human hand motion simulation has been investigated and we used one of most commonmethod named data-gloves which extract data from hand and then we simulated hand motion duringseveral...

In recent years, there has been a dramatic increase in the number of images captured by users. This is due to the wide availability of digital cameras and mobile phones which are able to capture and transmit images. Simultaneously, image-editing applications have become more usable, and a casual user can easily improve the quality of an image or change its content. The most common type of image...

In cooperative multi-agent path planning, agents must move between start and destination locations and avoid collisions with each other. Many recent algorithms require some sort of restriction in order to be complete, except for the Push and Swap algorithm [7], which claims only to require two unoccupied locations in a connected graph. Our analysis shows, however, that for certain types of inst...
