Stereo Match is one of the key fields in computer vision. Although many dense two-frame stereo algorithms have been developed in this domain, few utilize cross check and disparity gradient based refinement method. This paper proposes: (1) Cross check method using two generated disparity maps based on left and right original images. (2) A novel occluded and low-texture region growth method based on...
We present an efficient open-source implementation of a novel video alignment algorithm, based on low dimensionality frame matching and the recently introduced ECC image registration algorithm.
Serial number is a unique number given to a product which can be used for product identification and inventory management. Information about the product may be its manufacturing date, expiry date, place of manufacture and so on. Some companies use serial numbers to keep track on the number of products which a retailer is authorized to sell. Thus serial number identification becomes an important part...
This paper describes a voice navigational system for the visually impaired which runs on the user's smart-phone as an application and requires no additional expensive or heavy hardware. This system requires just the live video stream from the user's phone camera and an internet connection, and hence can be used on the most basic of smart-phones. The system proposed here identifies obstacles in front...
This paper proposed a technique to avoid collisions in the image sequences captured by stereo camera. It has to filter out the independently moving objects by performing ego-motion computation of the vehicle, so that the front moving objects and possible dangerous conditions may be detected using this collision avoidance system. The stereo computation generated the sparse disparity map of the object,...
Advanced driver assistance systems (ADAS) are designed to increase driver's situational awareness and road safety by providing essential information, warning and automatic intervention to reduce the possibility/severity of an accident. Of the various types of ADAS modalities available, camera based ADAS are being widely adopted for their usefulness in varied applications, overall reliability and adaptability...
The present paper analyzes the use of an embedded system-on-a-chip (SoC) platform, integrating a multicore ARM processor with FPGA fabric in a single chip, as a stereo vision pre-processing module, used to retrieve depth information from the features to compose 3D landmark points. The Harris and Stephens corner detector is applied to an image pair acquired from a stereo camera setup using a hardware...
The Internet of Things is a great vision but also an important challenge for the current research. Through, the connection of many different devices there are outstanding benefits such as an increasing automation and intelligent energy management. Nevertheless, the integration of legacy devices into the Internet of Things is a significant issue. Legacy meters, e.g., cannot provide metering data automatically...

Voxar Puzzle isa digital game in which children have to choose a puzzle froma virtual library and assemble it by manipulating physicalblocks. Furthermore, the process used for the development ofthe game platform had innovation in mind. A Blue Oceanstrategy...
Distributed smart cameras exploit smartphone processor performance in their node communication and video metadata exchange, allowing the network to collectively reason in interpreting the scene, generating alerts, and making decisions.
This paper presents the criteria for classification of the existing techniques for the development of navigation aid for the visually impaired people. Digital assistance for the visually impaired people to navigate easily even during the presence of static and moving obstacles has been a food for research over the years. The motivation for the current work is the development of a smart hearing aid...
This paper discusses a technology that is expected to widely spread in the near future, which is the Sixth Sense Technology. With this new technology yet to be introduced in the market, different implementation approaches are discussed. Such approaches are demonstrated through other inventions similar to the Sixth Sense (SS). They all fall into the same category, which is Augmented Reality Technologies...
Human Computer Interaction (HCI) is a fundamental issue for virtual reality environments due to the need for natural approaches and comfortable devices. Such goals can be achieved using hand gestures to interact with the virtual reality engine. This paper presents a real-time system based on hand gesture recognition (HGR) for interaction with CAVE applications. The whole pipeline can be roughly divided...

The objective of the project is to develop the advanced quality control inspection system makes use of distributed network architecture to interface the camera unit to a computer system through GigE LAN environment in a flexible way. The development work activity involves in dynamic capturing...
Integrating personal camera-equipped mobile devices in traditional camera networks could enable a new class of mobile vision applications, but although integration is becoming technically feasible, consumer buy-in could be a thorny problem.
A taxonomy of wireless visual sensor networks for surveillance offers design goals that try to balance energy efficiency and application performance requirements. SWEETcam, a wireless smart camera network platform, tries to address the challenges raised by achieving adequate energy-performance tradeoffs.
There is a increasing interest in creating wearable smartphone interaction technologies. A novel smartphone wearable hybrid interaction framework based on mixed low-cost hardware and software is proposed in this work.

This paper introduced muSurface, an interactive surface with ability to interact with tangible musical symbols. Children can explore musical symbols by placing the symbols on the virtual musical staffs displayed on the playing surface, and then the system plays the resulting melody. The system senses musical symbols on the surface using the rear diffused illumination technique, and displays the processed...
This paper presents a real-time trinocular disparity processor. The core module performs a pairwise segmented window matching for both the center-right and center-left image pair as their scaled down image pairs. The resulting cost functions are combined which results into nine different curves. A hierarchical classifier is presented which selects the most promising disparity value using information...
