As an important image processing technique, image interpolation has wide applications, such as digital photos, video communication, medical imaging, object identification. A new adaptive image amplification technique is presented in this paper. The proposed method is able to cope with arbitrary integer multiples image amplification. For a low-resolution (LR) image and a given integer magnification...
Character pose design is one of the most fundamental processes in computer graphics authoring. Although there are many research efforts in this field, most existing design tools consider only character body structure, rather than its interaction with the environment. This paper presents an intuitive sketching interface that allows the user to interactively place a 3D human character in a sitting position...
In this paper, we present a novel re-texturing approach using intrinsic video. Our approach begins with indicating the regions of interests by contour-aware layer segmentation. Then, the intrinsic video (including reflectance and illumination components) within the segmented region is recovered by our weighted energy optimization. After that, we compute the normals for the re-textured region, and...
In this paper, we present a novel depth-aware abstraction approach for videos. By introducing the additional depth cues, our approach is able to enhance the depth perception of the artistic-abstraction video. We first recover consistent depth information from the input video using multiview stereo and energy optimization algorithm. Then, the coherent line is extracted by employing the an isotropic...
A computer model for simulating pressure, flow propagation and oxygen transport in the circle of Willis is developed. The model is based on one-dimensional nonlinear equations of pulsatile fluid flow in an elastic tube and oxygen transport equation. The two-step Lax-Wendroff method was employed in the discretization of momentum and continuity equation, the upwind scheme was used in the discretization...
