| 1 | 用混合弹性模型解决图象变形匹配问题显示文摘由于用传统的刚体匹配方法难以解决待匹配图象之间的结构差异 ,因此需要引入变形模型来进行图象的非刚体匹配 .为此提出了一种利用混合弹性模型 (HEM)来解决图象变形匹配问题的新方法 .该方法不需要预先提取图象的特征 ,而是直接利用匹配图象之间的灰度信息来实现图象之间的匹配 .匹配时 ,首先通过基于主轴的方法来实现两幅图象之间的全局仿射匹配 ;然后利用线性弹簧网模型来求取两幅图象之间的相关性 ,并进一步利用薄板样条模型来实现两幅图象的变形匹配 .该方法在匹配过程中还采取了多分辨率匹配策略 ,合成图象和医学脑图象的实验结果表明 。 | 蔡志锋 卢汉清 Marc Jaeger | 2003 | 中国图象图形学报(A辑)2003，8，7： | 7 |
| 2 | Simulation and Visualisation of Functional Landscapes:Effects of the Water Resource Competition Between Plants显示文摘Vegetation ecosystem simulation and visualisation are challenging topics involving multidisciplinary aspects. In this paper,we present a new generic frame for the simulation of natural phenomena through manageable and interacting models.It focuses on the functional growth of large vegetal ecosystems,showing coherence for scales ranging from the individual plant to communities and with a particular attention to the effects of water resource competition between plants.The proposed approach is based on a model of plant growth in interaction with the environmental conditions. These are deduced from the climatic data (light,temperature,rainfall) and a model of soil hydrological budget.A set of layers is used to store the water resources and to build the interfaces between the environmental data and landscape components:temperature,rain,light,altitude,lakes,plant positions,biomass,cycles,etc.At the plant level,the simulation is performed for each individual by a structural-functional growth model,interacting with the plant's environment.Temperature is spatialised,changing according to altitude,and thus locally controls plant growth speed.The competition for water is based on a soil hydrological model taking into account rainfalls,water runoff, absorption,diffusion,percolation in soil.So far,the incoming light radiation is not studied in detail and is supposed constant.However,competition for light between plants is directly taken into account in the plant growth model.In our implementation,we propose a simple architecture for such a simulator and a simulation scheme to synchronise the water resource updating (on a temporal basis) and the plant growth cycles (determined by the sum of daily temperatures). The visualisation techniques are based on sets of layers,allowing both morphological and functional landscape views and providing interesting tools for ecosystem management.The implementation of the proposed frame leads to encouraging results that are presented and illustrate simple academic cases. | Vincent Le Chevalier Marc Jaeger 梅兴 Paul-Henry Cournède | 2007 | Journal of Computer Science & Technology2007，22，6： | 2 |
| 3 | Level of detail technique for plant models显示文摘Realistic modelling and interactive rendering of forestry and landscape is a challenge in computer graphics and virtual reality.Recent new developments in plant growth modelling and simulation lead to plant models faithful to botanical structure and development,not only representing the complex architecture of a real plant but also its functioning in interaction with its environment.Complex geometry and material of a large group of plants is a big burden even for high performances computers,and they often overwhelm the numerical calculation power and graphic rendering power.Thus,in order to accelerate the rendering speed of a group of plants,software techniques are often developed.In this paper,we focus on plant organs,i.e.leaves,flowers,fruits and inter-nodes.Our approach is a simplification process of all sparse organs at the same time,i.e.,Level of Detail(LOD),and multi-resolution models for plants.We do explain here the principle and construction of plant simplification.They are used to construct LOD and multi-resolution models of sparse organs and branches of big trees.These approaches take benefit from basic knowledge of plant architecture,clustering tree organs according to biological structures.We illustrate the potential of our approach on several big virtual plants for geometrical compression or LOD model definition.Finally we prove the efficiency of the proposed LOD models for realistic rendering with a virtual scene composed by 184 mature trees. | Xiaopeng ZHANG Qingqiong DENG~ Marc JAEGER | 2006 | 中国体视学与图像分析2006，11，4： | 2 |
