How to automatically implement shape morphing for Chinese characters represented in different styles is a challenging task. In this paper, we propose a novel method to solve this problem. Specifically, we first generate the shape template, which ...

This paper presents a new method to approximate animation sequences through a nonlinear analysis of the spatiotemporal data. The main idea is to find a spline curve which best approximates a multivariate animation sequence in a reduced subspace. Our ...

Hand-drawn animations are fascinating due to their expressiveness. In the production pipeline, manual coloring of line drawings is tedious and labor-intensive. We propose a method for accelerating the coloring step by matching corresponding regions in ...

This paper describes a hybrid technique to produce physically plausible response for animated character. The approach includes the automatic, adaptive selection of the dynamic articulation necessary for local-body responses based on the changing ...

We present an image decomposition method using L1 fidelity term with L0 norm of gradient to decompose an image into base layer and detail layer. Generally, the L1 fidelity should be preferable to the L2 norm when the erroneous measurements exist. It is ...

We present a method for embedding video clips within gigapixel scale imagery. The combination of high-resolution imagery and video enables users to pan and zoom across the gigapixel panorama to explore complex scenes with motion. The sparsity of the ...

In this paper an algorithm for gradient domain color-to-gray conversion is described. By enhancing the luminance gradient with the chromatic difference in CIELAB space, a gradient field is created to construct the resulting gray-scale image using a ...

The anaglyph image, primarily used for red-cyan eyeglasses, has the following flaws: it only reproduces partial colors, often brings retinal rivalry and ghosting to viewers. In this paper, we propose a method for anaglyph image recoloring to enhance the ...

The seamless collaboration between real objects and virtual information is a challenging issue for effective information displays in various fields, including museum exhibitions, advertisement, and digital signage. Former studies on displaying ...

We present a novel 2D-3D matching method, which is applicable to the pose detection of a target 3D object for an AR application. Our method matches 2D keypoints against their corresponding 3D points directly with a classification approach, and ...

Augmented reality applications on hand-held devices suffer from the limited available processing power. While methods to detect the location of artificially textured markers within the scene are commonly used, geometric properties of three-dimensional ...

In this project, we propose an interactive content creation and editing system for haptic-enabled 3D content by drawing shapes in the air and copying and pasting surface textures. To achieve realistic haptic interaction, we create a data structure for ...

We present a scalable method to procedurally animate and render vast ocean scenes with whitecaps on the GPU. The whitecap coverage on the ocean surface is determined using a wave deformation criteria which can be pre-filtered linearly. This allows us to ...

Point-based scanning is commonly used for 3D data acquisition. Applications can simply adopt a point cloud representation avoiding the computational complexity of connectivity construction. Despite many state-of-the-art algorithms discussing point cloud ...

While efforts to create realistic images have generated break-throughs in computer graphics modeling, there has been little research to date on factors causing people to perceive images as real versus computer-generated (CG). The motivation of the ...

In recent years, deferred rendering, dating back to [Saito and Takahashi 1990], has gained in popularity for rendering in real time, especially in games. A deferred-rendering pipeline is good at dealing with many lights. However, it is not suited for ...
