A Novel Approach to Background Subtraction Using Visual Saliency Map
Generally human vision system searches for salient regions and movements in video scenes to lessen the search space and effort. Using visual saliency map for modelling gives important information for understanding in many applications. In this paper we present a simple method with low computation load using visual saliency map for background subtraction in video stream. The proposed technique i...
متن کاملSaliency map augmentation with facial detection
Visual attention is very important in human visual perception. It is the ability of a vision system to detect salient objects in an observed scene. This scientific discipline has been studied for over a century. Nowadays it is involved in the disciplines of psychophysics, cognitive neuroscience and computer science. This paper describes several visual attention models for detecting salient obje...
متن کاملA Learned Saliency Map for Eye Detection
In this paper, a method of constructing saliency map based on learning method is proposed. The saliency map is constructed by nonlinear combination of features, and the nonlinear function is approached through a feed forward artificial neutral network (ANN) whose weight is trained by examples. The efficiency of the proposed method is verified in the eye detection problem. Experiments show that ...
متن کاملDevelopment of an Audio - Visual Saliency Map
General Presentation of the Research Domain The focus of the REVES research group is on image and sound synthesis for virtual environments. Our research is on the development of new algorithms to treat complex scenes in real time, both for image rendering (for example the capture and rendering of trees using an image-based technique [1]) or for sound (for example using perceptual masking and cl...
متن کاملA saliency map in primary visual cortex.
I propose that pre-attentive computational mechanisms in primary visual cortex create a saliency map. This map awards higher responses to more salient image locations; these responses are those of conventional V1 cells tuned to input features, such as orientation and color. Hence no separate feature maps, or any subsequent combination of them, is needed to create a saliency map. I use a model t...
