Refractive Calibration of Underwater Cameras
In underwater computer vision, images are influenced by the water in two different ways. First, while still traveling through the water, light is absorbed and scattered, both of which are wavelength dependent, thus create the typical green or blue hue in underwater images. Secondly, when entering the underwater housing, the rays are refracted, affecting image formation geometrically. When using...
متن کاملDetecting abnormal human behaviour using multiple cameras
In this paper a bottom-up approach for human behaviour understanding is presented, using a multi-camera system. The proposed methodology, given a training set of normal data only, classifies behaviour as normal or abnormal, using two different criteria of human behaviour abnormality (short-term behaviour and trajectory of a person). Within this system an one-class support vector machine decides...
متن کاملAdaptive elevator group control with cameras
A new elevator group control system is proposed. The system learns dynamic traffic flows by analyzing passenger traffic without prespecified patterns. A genetic algorithm continuously generates dispatch functions according to changes in passenger traffic. By considering the status inside elevators, the directions of passenger movement, and the number of waiting passengers, the system occasional...
متن کاملGroup Behavior Recognition With Multiple Cameras
We propose in this paper an approach for recognizing group of people behaviors using multiple cameras with overlapping FOVs (Field Of View). In this context, Behavior recognition first relies on low level motion detection and frame to frame tracking which generate a graph of mobile objects for each camera. Second, to take advantage of all cameras observing the same scene, a combination mechanis...
متن کاملLearning People Movement Model from Multiple Cameras for Behaviour Recognition
In surveillance systems for monitoring people behaviour, it is imporant to build systems that can adapt to the signatures of the people tasks and movements in the environment. At the same time, it is important to cope with noisy observations produced by a set of cameras with possibly different characteristics. In previous work, we have implemented a distributed surveillance system designed for ...
