A CODOG system simulation model is builded using the Matlab/SIMULINK, and the model is verified by the data from the design-department. Then the model is improved by using RTW and MFC, and could run without SIMULINK. Then three different engine load control methods of accelerating process are proposed, and each method is designed and simulated. The simulation result shows that the subsection optimizing...
This paper discusses teaching reform ideas in the ldquoscientific computingrdquo education by means of modeling and simulation, that can make students get a better understanding of the background, concept and design of each numerical algorithm in ldquoscientific computingrdquo education, and it will help them enhance their self-learning ability and exploration ability.
It is the key problems in 3D model retrieval to obtain good feature and classify models efficiently. Although many feature extraction methods have been proposed, none is adapted to all models. Moreover, it still relies on manual work to classify models. To solve these problems, firstly, the paper proposes a series of selective combination methods which automatically decide each feature's appropriate...
3D model retrieval emerges as an important part of multimedia information retrieval. Current researches in 3D model retrieval concentrate on the shape-based way. However, its performance isn't satisfying because of the semantic gap. The paper explores the semantic-based 3D model retrieval method based on semantic tree and the hybrid method based on content and semantic. First, the semantic tree is...
Cast shadows induced by moving objects often cause serious problems to many vision applications. We present in this paper an online statistical learning approach to model the background appearance variations under cast shadows. Based on the bi-illuminant (i.e. direct light sources and ambient illumination) dichromatic reflection model, we derive physics-based color features under the assumptions of...
In this paper, we propose a new re-coloring algorithm to enhance the accessibility for the color vision deficient (or colorblind). Compared to people with normal color vision, people with color vision deficiency (CVD) have difficulty in distinguishing between certain combinations of colors. This may hinder visual communication owing to the increasing use of colors in recent years. To address this...
