As a challenging topic in computer graphics and computer vision, 3D face modeling has been applied in various fields including film and animation production, game development as well as medical analysis. In this paper, we mainly aims at face personalized modeling optimization based on KINECT2. The optimization of the scheme proposed is the mesh deformation based on the differential coordinates constrained...
With the diversification and ever-changing forms of video programs and advertising information, the application of video corner-logo is more and more widely used. Corner-logo detection can be used for video content recognition and interaction, information analysis, monitoring and other aspects of advertisements. An effective corner-logo detection algorithm is the key to corner-logo extraction and...
In this paper, a visual tracking algorithm based on adaptive background modeling and improved particle filter was proposed, which can be effectively used to track the players in sports video. Adaptive background modeling was used to extract motion information in the dynamic scene, and obtained precise motion region through a designed target selection filter, then, do the tracking algorithm under particle...
In order to improve the robustness of the existing character recognition systems and increase their recognition ratio under various bad illumination conditions, we proposed a fast image enhancement algorithm based on illumination-reflectance model, by using an approximate edge-preserved filter. Experimental results showed that our algorithm can greatly help increase the character recognition ratio...
Vehicle analysis is an important task in many intelligent applications, which involves vehicle-type classification(VTC), license-plate recognition(LPR) and vehicle make and model recognition(MMR). Among these tasks, MMR plays an important complementary role with respect to LPR. In this paper, we propose a novel framework to detect moving vehicle and MMR using convolutional neural networks. The frontal...
Facial expression details can largely enhance the realistic facial animation. In this paper, we proposed a method to realize real-time control of 3D facial subtle expression, such as wrinkles and bulges, based on a set of normal maps. At runtime, we used a kinect to get the animation units for calculating control parameter. Normal blending technology was used to blend the base normal map and the detail...
TV logo recognition plays an important role in video content understanding. So far, Real-time TV logo recognition under complex background based on single frame is still a very challenge task. By analyzing the characteristics of TV logo, a new TV logo recognition algorithm based on multiple feature fusion via hierarchical matching was proposed in this paper. The recognition process consisted of three...
Aimed at the problem for low accuracy of athlete number positioning under the complicated background, an algorithm of localization which based on edge detection and color features was presented. First, the edge detection method on the basic of the character features of athlete number was applied to the athlete number image. Then, the binary image processing was carried on by selecting an optimal threshold,...
TV corner-logo is widely used in current video program, and becomes one of the hot spots in information extraction and analysis. TV corner-logo detection and segmentation algorithm is important for information extraction. In this paper, we presented an adaptive threshold segmentation algorithm, based on the combined time-averaged edge detection and saliency detection, to effectively separate and extract...
Performance-driven facial expression animation is one of the researching highlight in computer animation. In this paper, a method is proposed to control 3D facial expression animations in real time. The skeleton based on skinning was adopted for an efficient control of the deformation of the face model. Kinect was used as a capture device to get the depth and color images of the performers that help...
With the vigorous development of 3D graphics and the Internet platform, the research of personal face deformation and face modeling of high quality is more and more important. In this paper, some experiments are made aiming at the process that is to create personalized model from the neutral face model by data matching and automatic deformation. We use Laplacian mesh editing as the mathematical method,...
HyperText Markup Language (HTML) is the main markup language for web pages. HTML5 is a new generation of HTML standards. With the development of HTML5, it has wide range of applications in the multimedia direction. This new standard first describes the Video and Audio tag, and then elements of Video and Audio are discussed, pointing out that the support of the current browser to Video and Audio format...
Compressive sensing is an emerging technology which can recover a K-sparse signal vector from M = O(Klog(K=N)) measurements. However, it is a challenge to know exactly how many measurements an image requires to achieve an acceptable recovered visual quality. In this paper, we study the relationship between the image's complexity and its sparsity. We propose a mathematical model to estimate the number...
In data-driven mesh-based P2P live streaming system, the playback buffer management affects the audiences' quality of experience (QoE) significantly. Due to the instability and heterogeneity of P2P networks, the buffer is not always ready for playback. It is not only associated with the media timestamp, but also with the data availability in its neighbors. So how to manage the buffer synchronization...
