Stereoscopic displays are becoming very popular since more and more contents are now available. As an extension, auto-stereoscopic screens allow several users to watch stereoscopic images without wearing any glasses. For the moment, synthetized content are the easiest solutions to provide, in realtime, all the multiple input images required by such kind of technology. However, live videos are a very...
Light field rendering (LFR) is an image-based method for generating novel views from a set of camera images. When sample of camera array is sparse, conventional light field rendering would cause aliasing artifacts. We present a straightforward layer-based method that significantly removes the aliasing artifacts with no prior knowledge of the scene geometry. First, a sparse disparity map is generated...
We propose a passive image splicing detection method based on consistency check of color distribution in the neighborhood of edge pixels. For a given image, we classify edges into different categories and extract shadow-shading-specular invariant edges as the candidate of splicing boundaries. Hue histogram entropy is then computed to capture abnormality of color distribution at these boundaries. Inconsistency...
This work aims at investigating the influence of luminance information and environment illumination on skin classification. We explore Bayesian approaches to perform automatic classification of human skin pixels on digital images, using color features as input. Two probabilistic skin color models were built on different color spaces (RGB, normalized RG, HSI, HS, YCbCr and CbCr) and tested in a task...
This paper presents an experimental study on object recognition and self-localization for multiagent robotic soccer. A color image segmentation method based on UV color information of each pixel of the color image is applied to the ball recognition and self-localization of a small mobile robot. First, the lower and higher threshold values of U and V are determined for the sample color markers. Then...
Not only the paper is going to give a brief introduction of the process of paperless animation platform as well as its module division, but also analyze and probe into the main function of different modules and the principles about how to realize the module technology.
