A real-time object detection algorithm by using multiple cameras is proposed. The information fusion is based on homographic transformation of the foreground information from multiple cameras to a reference image. Unlike the most recent algorithms which transmit and project foreground bitmap images, we approximate the contour of each foreground region with a polygon and only transmit and project the...
We present an adaptive multi-lateral filter for real-time low-resolution depth map enhancement. Despite the great advantages of Time-of-Flight cameras in 3-D sensing, there are two main drawbacks that restricts their use in a wide range of applications; namely, their fairly low spatial resolution, compared to other 3-D sensing systems, and the high noise level within the depth measurements. We therefore...
This paper proposes a framework to perform volumetric 3D reconstruction using a camera network. A network of cameras observes a scene and each camera is rigidly coupled with an Inertial Sensor (IS). The 3D orientation provided by IS is used firstly for definition of a virtual camera network whose axis are aligned to the earth cardinal directions. Then a set of virtual planes are defined for the sake...
In this demo we will present a vision-based smart environment using in-car cameras that can be used for real time tracking and monitoring of a driver in order to detect the driver's drowsiness based on yawning detection. As driver fatigue and drowsiness is a major cause behind a large number of road accidents, the assistive systems that monitor a driver's level of drowsiness and alert the driver in...
This paper describes the integration of distributed image analysis in a smart camera network with a control application. The distributed smart cameras analyze the environment of the controlled object and transfer accurate position and orientation information of all detected obstacles to the controller within guaranteed time bounds. With this information the controller can optimize the trajectory of...
In order to support real-time face recognition using a wireless camera network, we design a data acquisition service to quickly and reliably acquire face images of human subjects from multiple views and to simultaneously index each acquired image into its corresponding pose. In comparison with detection of frontal faces, the detection of non-frontal faces with unknown pose is a much more challenging...
An IP camera based on TI's DaVinci DSP-TMS320DM6437 is developed in this paper. An intelligent video surveillance system is established using the designed IP camera. The real-time capture of the video is implemented in the system as well as the compression coding of the video using H.264 and the transmission of the encoded video through network. In the section of network communication, the performance...
While for static cameras several background subtraction approaches have been developed in the past, for non-static pan/tilt cameras efficient and robust motion detection is still a challenging task. Known approaches use image-to-image registration methods to generate a panorama background model of the scene, which spans a joint pixel coordinate system for later background estimation and subtraction...
In this paper, we describe how information obtained from multiple views using a network of cameras can be effectively combined to yield a reliable and fast human action recognition system. We describe a score-based fusion technique for combining information from multiple cameras that can handle arbitrary orientation of the subject with respect to the cameras. Our fusion technique does not rely on...
The design and implementation of network camera based on embedded Linux system and the TMS320DM356 processor is put forward which can be operated on 5-megapixel. At 30 frames per second in full frame rates, It is the video stream up to 2Mbps bit rate to provide resolution of 1280×720 pixels. The sampled video stream which compressed and encoded by the protocol of H.264 can be transferred in the network...
This paper is concerned with the design and development of a semi-autonomous wheelchair system using cameras in a system configuration modeled on the vision system of a horse. This new camera configuration utilizes stereoscopic vision for 3-Dimensional (3D) depth perception and mapping ahead of the wheelchair, combined with a spherical camera system for 360-degrees of monocular vision. This unique...
The CCD slow-motion camera was used for continuously shooting granulometric micro-image in order to reaLize dynamically and continuously gathering granulometric micro-images. The VC.NET in VS2008 IDE was used for developing the analytical software for dynamic granulometer. It can do real-time analyses for particles in consideration of the dynamics and continuity of granulometric micro-image continuous...
In this paper, we proposed a tensor-based hand-held projection system that makes use of pure computer vision techniques. Using a projector and two cameras, the system is able to spatially augment content on movable rigid surfaces, such as a map or a book. The advantage of our system is that neither attachment of sensors to the projection surface nor the prior reconstruction of the surface structure...
In this paper, we present an architecture for a video analytics framework, specifically designed for automatic enrollment and subsequent re-identification of faces on a network of cameras. The proposed system can be used as an assistive tool for applications such as passenger screening at airports as passengers walk through various sections of the airport.
In this demo we present a people tracker in indoor environments. The tracker executes in a network of smart cameras with overlapping views. Special attention is given to real-time processing by distribution of tasks between the cameras and the fusion server. Each camera performs tasks of processing the images and tracking of people in the image plane. Instead of camera images, only metadata (a bounding...
We present an academically developed framework for real time computations in Micro UAVs and Ground Robotics. Dynamic Partial Reconfiguration is used as a hardware accelerator in a heterogeneous environment which enables computationally demanding applications to take effective advantage of adaptive hardware resources while maintaining a high flexibility of software. We demonstrate our hypothesis by...
When you look at the object, the displacement of object is different in left and right eye. This displacement is called parallax. The farther the object is, the smaller the parallax become. Due to the parallax, people will have the feeling of stereoscopic vision. We develop a depth-image-based rendering (DIBR) algorithm to shift (or move) the position of the object in the image to generate the stereoscopic...
