Gesture recognition is important in the humancomputer interaction. In this paper, a method for detecting fingertips and gesture recognition using Cubic B-Spline Curve Fitting is proposed. The main steps in the method include: skin segmentation, palm and fingertips extraction, gesture trajectory extraction. According to transform RGB color space to YCrCb, the region of hand can be extracted using OSTU...
Dual-energy X-ray imaging is a well-established technique to color code X-ray images of travelers' luggage with materials discrimination information. Existing dual-energy X-ray technologies are capable of calculating the effective atomic number of objects with high accuracy. However, dual-energy analysis alone is unable to isolate innocuous organic objects from threat objects as their correct classification...
In this paper, we propose a salient region detection method for textured 3D models. We define the salient region, not only based on geometry properties, such as mean curvature, but also based on texture properties, such as texture color. Feature maps of geometry and texture are combined to form a saliency map for capturing the visually important regions of a textured 3D model. During the feature maps...
A digital watermarking method for color image in wavelet domain is proposed. The watermarking information which include a section of template information, is embedded into low-frequency coefficients of Y component in YUV color space. This section of template information defines a kind of relation between the low-frequency coefficients corresponding to the four sub-images obtained by down-sampling...
