Visual Evaluation of Video Features
نویسندگان
چکیده
When using visual video features in an interactive video index environment, it is necessary to visualize the meaning and impact of features to people that are not image processing experts, such as video librarians. Projection of feature values on the original video data is an important method to visualize the relation between the feature and the video. We describe the characteristics of features with respect to visualization and distinguish requirements for feature visualization. Furthermore, we propose to use the backprojection method to visualize features. We have developed the VidDex system which uses backprojection on various video visualization modes. By combining the visualization modes the requirements can be met for the feature characteristics identified.

The video quality assessment must be adapted to the human visual system, which is why researchers have performed subjective viewing experiments in order to obtain the conditions of encoding of video systems to provide the best quality to the user. The objective of this study is to assess the video quality using image features extraction without using reference video. RMSE values and processing ...
متن کاملA 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 کاملProbabilistic home video structuring: feature selection and performance evaluation
We recently proposed a method to find cluster structure in home videos based on statistical models of visual and temporal features of video segments and sequential binary Bayesian classification. In this paper, we present analysis and improved results on two key issues: feature selection and performance evaluation, using a ten-hour database (30 video clips, 1,075,000 frames). From multiple feat...
