Colour-based object recognition under spectrally non-uniform illumination
This paper describes a colour-based recognition system with three novel features. Firstly, the proposed system can operate in environments where spectral characteristics of illumination change in both space and time. Secondly, benefits in terms of speed and quality of output are gained by focusing processing to areas of salient colour. Finally, an automatic model acquisition procedure allows ra...
متن کاملReal-Time Object Tracking Using Colour Feature
Video Tracking is the process of locating a moving object over time using a camera. The objective of video tracking is to associate target objects in consecutive video frames. The association can be especially difficult when the objects are moving fast relative to the frame rate. Another situation that increases the complexity of the problem is when the tracked object changes orientation over t...
متن کاملColour and Feature Based Multiple Object Tracking Under Heavy Occlusions
Tracking multiple objects in surveillance scenarios involves considerable difficulty because of occlusions. We report a composite tracker based on feature tracking and colour based tracking that demonstrates superior performance under high degrees of occlusion. Disjoint foreground blobs are extracted by using change masks obtained by combining an online-updated background model and flow informa...
متن کاملFeature localization and search by object model under illumination change
Color object recognition methods that are based on image retrieval algorithms can handle changes of illumination via image normalization, e.g. simple color-channel-normalization or by forming a doubly-stochastic image matrix. However these methods fail if the object sought is surrounded by clutter. Rather than directly trying to nd the target, a viable approach is to grow a small number of feat...
متن کاملLocale-Based Visual Object Retrieval under Illumination Change
Providing a user with an effective image search engine has been a very active research area. A search by an object model is considered to be one of the most desirable and yet difficult tasks. An added difficulty is that objects can be photographed under different lighting conditions. We have developed a feature localization scheme that finds a set of locales in an image. We make use of a diagon...
