Gesture Computing is a technology that allows hand movement and facial expressions as input controls. Many devices are used now-a-days for capturing images and storing in their mass storage devices provided within them like digital camera with memory cards, mobile phones with inbuilt memory and memory cards, etc. We focus on capturing images and storing them by using gesture computing method in MATLAB...
This paper discusses an inverse problem where internal stiffness parameters are determined by both applied force and deformation of object. By supposing a soft tissue, we first propose the simplest tissue model that can express the coupling effect where the tissue deforms not only at the point of force application but also its surrounding area. We explain the way for determining the internal stiffness...
This paper presents innovative driving method for the magnetically driven microtools (MMT) which is micrometer positioning accuracy by horizontally arranged permanent magnets. A piezoelectric ceramic is used to induce nanoscale vibration to the microfluidic chip to reduce the friction on the MMT. The enucleation process has been conducted by the dual arm MMTs. MMTs receive enough driving power supplied...
The challenges associated with wireless vision sensor networks are low energy consumption, less bandwidth and limited processing capabilities. In order to meet these challenges different approaches are proposed. Research in wireless vision sensor networks has been focused on two different assumptions, first is sending all data to the central base station without local processing, second approach is...
In this paper, a full 3D reconstruction pipeline is presented to realize the navigation of an autonomous robot. The system utilizes the existing algorithms for multi-view stereo and develops them into an automated system where the input is a video (or random images) obtained by the robot and the output is the model of the reconstructed environment containing the path of the robot exploring it. We...
Improving the quality of summaries created for the documents explored during informational search is the essential point in the interpretation of search engine results. In many cases summaries generated by the search engines are not indicative enough, therefore the user cannot quickly judge about the document relevancy. Having the WordNet ontology based weighting procedure proposed in earlier works...
Gestures and utterances are useful factors in communication. A gesture or an utterance has different meanings depending on related objects, situation and so on. Authors aim that a system recognizes these interactions' meanings and provides a service considering related objects. Proposed system combines gesture recognition and speech recognition as multimodal interaction, and manages the database with...
This paper describes an FPGA-based system capable of computing the distance of objects in a scene to two stereo cameras, and use that information to isolate objects in the foreground. For this purpose, four disparity maps are generated in real time, according to different similarity metrics and sweep directions, and then merged into a single foreground-versus-background bitmap. Our main contribution...
To develop a quick detection algorithm for the image-based autonomous vehicle (AV) or computer assisted driving system, this paper proposes a real-time object detection method using two coordinated cameras. The mapping between two simultaneous images from the two cameras and coordination of the virtual sensitive areas can be resolved using parameters like the camera shot angle, the camera focal length,...
In order to detect the location of smoke in the Measuring System for Ground Shell Dispersion (MSGSD), presented an improved algorithm for the Background Subtraction. Focused on introducing design of the image detection algorithm. The results show that the system can quickly, accurately and effectively detect the location of the smoke.
In-class demonstration experiments give the real time validation or illumination about conceptual theory, especially in the science and engineering teaching progress of undergraduate education. This paper discusses the development and application of an new apparatus based on virtual instrument for in-class experiments demonstrations when the lecture topics need electronic test process. The apparatus...
The objective of this paper is to develop a localization system for cooperative multiple mobile robots, in which each robot is assumed to observe a set of known landmarks and equipped with an omnidirectional camera. If only a limited number of landmarks are available, it suffers from law accuracy. In this paper, it is assumed that a robot can detect other robots by using the omnidirectional camera...
This paper discusses a perceptual system for intelligent robots. Robots should be able to perceive environments flexibly enough to realize intelligent behavior. We focus on a perceptual system based on the perceiving-acting cycle discussed in ecological psychology. The perceptual system we have proposed consists of a retinal model and a spiking-neural network realizing the perceiving-acting cycle...
To solve the non-uniformity problem of multi Time Delay Integral Charge Couple Device (TDICCD) mosaic camera, a non-uniformity correction algorithm is proposed and implemented on Field-Programmable Gate Array (FPGA) platform. Firstly, the generation and definition of non-uniformity are introduced; several common non-uniformity correction methods are discussed. Secondly, the correction algorithm is...
Image stitching are ideally suited for applications such as image stabilization, summarization, and the creation of panoramic mosaics. This paper proposes a approach to stitch images fast and with high quality.Image alignment algorithms can discover the correspondence relationships among images with varying degrees of overlap. In this process, they uses SIFT to look for the trait points, and uses...
For multi-channel high-speed image data of certain space remote sensing camera, this paper proposed a new image data acquisition and storage system. First of all, the system uses Field-Programmable Gate Array(FPGA) controlling synchronous dynamic random access memory(SDRAM) array to realize the cache of image data, then according to the received commands, sends certain channel's image data to the...
A key problem of attitude measurement of small-multi-target with high speed is how to decide the optimum of the CMOS stations. A multi-CMOS station mode is designed in this paper, multiple CMOS videos were placed on two parallel sides in measurement system, every two CMOS form an intersection viewing field, multiple viewing field join to cover shooting range, which can augment Effective Viewing Field...
In the process of producing copper bar, because of the cast copper billet, rolling equipment, rolling process and other reasons, the surface of copper bar appear some defects such as crack, scarring, roller printing, scratches, holes, scales, pitting, and so on. These deficiencies not only affect the appearance of the product, but more importantly reduce the product's corrosion resistance, abrasion...
