Due to the existence of complicated illumination, background and variations of pose, fast and robust face detection is constrained in many applications. This paper describes a novel scheme conceived to integrate multiple cues to detect face under in-plane rotation, Concretely, we apply skin-color, heuristic rules and eye feature to build a robust detector. First, skin detection approach based on novel...
This paper presents a fast algorithm to detect the road lines and the road edges of structured and unstructured roads, respectively. In structured road detection, we firstly utilize vertical Sobel mask and color characteristic to detect the points of road lines. If the number of points is greater than a predefined threshold, we refine the detection results with slope filtering. And the least square...
In this paper, a new image retrieval method, which uses the two primary features of image cluster to retrieve image, i.e., the average color value and the number of pixels for each cluster, is proposed. In comparison with popular methods, since this method uses both color feature and structure feature, it is good to solve such a sort of image retrieval questions for two images that they are similar...
The extraction of textual content from colour documents of a graphical nature is a complicated task. The text can be rendered in any colour, size and orientation while the existence of complex background graphics with repetitive patterns can make its localization and segmentation extremely difficult. Here, we propose a new method for extracting textual content from such colour images that makes no...
Analytic characterizations of the posterior distribution of a random finite set of states, conditioned on image observations are derived; under the assumption that the regions of the observation influenced by individual states do not overlap. These results provide tractable means to jointly estimate the number of states and their values in the Bayesian framework. As an application, we develop a multi-object...
Virtual view synthesis is a key technology for future free viewpoint video and three-dimensional video applications. A novel asymmetric bidirectional view synthesis method is proposed for multi-view video plus depth based systems. An intermediate virtual view is synthesized based on two adjacent reference views, which are termed as the main view and the auxiliary view. The main view contains two-dimensional...
