Cities around the world are increasingly relying upon cameras to provide visual coverage of extended spaces. Surveillance cameras are an essential component of the overall crime prevention strategy. Law enforcement agencies now heavily use imagery collected by surveillance cameras in solving crimes. Cameras installed on roadways are used to collect traffic data with the aim to better manage tra...

We present a novel approach for video partitioning by detecting three essential types of camera breaks, namely cuts, wipes, and dissolves. The approach is based on the analysis of temporal slices which are extracted from the video by slicing through the sequence of video frames and collecting temporal signatures. Each of these slices contains both spatial and temporal information from which coh...

Smart video analytics algorithms can be embedded within surveillance sensors for fast in-camera processing. This paper presents a DSP embedded video analytics system for object and people tracking, using a PTZ camera. The tracking algorithm is based on adaptive template matching and it employs a novel Sum of Weighted Absolute Differences. The video analytics is implemented on the DSP board DM64...

Acquisition of stabilized video is an important issue for various type of digital cameras. This paper presents an adaptive camera path estimation method using robust feature detection to remove shaky artifacts in a video. The proposed algorithm consists of three steps: (i) robust feature detection using particle keypoints between adjacent frames; (ii) camera path estimation and smoothing; and (...

In the present or recent times people want to collect their memorable moments with the help of digital devices like. camera. Digital videos becoming grown and found anywhere. So camera plays a vital role in our day to day life. However editing and organizing videos remains difficult for people by different reasons. Also searching takes more time. So people need a better solution for video editi...

The integration of advanced CMOS image sensors with high-performance processors into an embedded system facilitates new application classes such as smart cameras. A smart camera combines video sensing, video processing and communication within a single device. This paper reports on the prototype implementation of a smart camera for traffic surveillance. It captures a video stream, computes traf...

While there are various commercial-strength editing tools available today for still images, object-based manipulation of real-world video footage is still a challenging problem. In this system paper, we present a framework for interactive video editing. Our focus is on footage from a single, conventional video camera. By relying on spatiotemporal editing techniques operating on the video cube, ...

Smart cameras combine video sensing, video processing and communication onto a single embedded device. Due to their high onboard processing and communication power they are able to perform sophisticated video tasks in real time and can, therefore, react to changes in the camera’s environment. Such embedded smart cameras are excellent candidates for reactive sensor systems. In this paper we desc...

Camera tampering may indicate that a criminal act is occurring. Common examples of camera tampering are turning the camera lens to point to a different direction (i.e., camera motion) and covering the lens by opaque objects or with paint (i.e., camera occlusion). Moreover, various abnormalities such as screen shaking, fogging, defocus, color cast, and screen flickering can strongly deteriorate ...

Free-viewpoint video allows interactive control of the camera viewpoint in video playback using a three-dimensional (3D) scene representation. This paper describes the challenges and the state-of-the-art techniques adopted in developing a free-viewpoint renderer for 3D video production of people. The system requires video streams from a set of fixed or dynamic real-world video cameras and synth...
