Image enhancement is an important function of stereoscopic endoscopy. 3D images of stereoscopic endoscopy usually suffer from various kinds of degradation because of undesired noise, inhomogeneous brightness and poor contrast. In addition, it often contains color mismatch and different luminance between two stereo views. It will lead to many problems applying traditional image enhancement methods...
In this paper, we aim to improve one of the current state-of-the-art models for facial components detection/localization. The objectives are to increase the amount of landmark points detected and improve the landmark extraction accuracy for frontal faces. The model is following Zhu and Ramanan's approach with a tree-structure. The popular AR dataset is chosen as an alternative training dataset as...
This paper presents a robust and fully-automatic human motion tracking system without motion priors information using a camera in a fixed location. Bottom-up estimation approaches have recently been applied to such tasks with some success. However, the performance of these approaches is limited by the difficulty of building an effective appearance model. In particular, the appearance model must be...
A new image retrieval algorithm based on color of image blocks and moment invariant of image was presented. First of all, the image is converted to HSV color space, then the image is separated into sub-blocks, and it gets the color histogram in each block as the image color feature. Meanwhile, it uses seven HU moment invariant and eccentricity to describe shape feature. Finally, the similarity is...
For the inevitable factors in the practical scene such as illumination chance and background interference, a new method is obtained to achieve the detection of human movement in this paper. This algorithm can remove most of the shadow and apply Gaussian filter to reduce interference. Then the moving targets under different conditions can be accurately tracked by combination of tracking algorithm and...
Volume Haptics is used for enhanced visualization and interaction of volumetric data. In this paper, evaluation of VHTK is presented which implements direct volume haptics with proxy based approach. The techniques are tested on medical and geophysical data. Different haptic modes are used that are controlled with transfer functions as parameters representing material properties.
With the digital technology developments, Digital Cinema outperforms traditional films and attracts the movie industry. The first edition Digital Cinema System Specification was released by Digital Cinema Initiatives, LLC (DCI) in 2005, which advances the Digital Cinema development. We have developed a Digital Cinema Playback system compliant with the DCI Specification. It can extract and play the...
