This project is to investigate the techniques that use textures to enhance the exhibition of surface details in 3D computer generated images. It is generally recognised that one of the major differences between real world images and computer synthesized images lies in the exhibition of high-frequency visible surface details. This project will be an effort to bridge this major gap.The principal objective of this project is to develop a key technique called Amplifiable Bi-directional Texture Function (ABTF). ABTF is designed to generate textures on 3D surface models. Compared with the conventional texture mapping/synthesis techniques, ABTF will have the following strengths:1) It will not compromise on texture quality in close-up views; 2) It will accurately display significant visual effects of fine surface details, including self-shadowing and occlusion, inter-reflection and silhouettes, under different viewing/lighting settings.3) It will take into consideration the influence from the variations of target surface curvatures for the correct synthesis and display of textures. The ABTF synthesis will be based on a hybrid image modelling and rendering approach. Given multiple views of a texture sample, it will recover the underlying geometries of the texture and use them as surface details for the target surface. For high visual fidelity purpose, the colours of the target surface will be obtained from the images of the multiple views through a quick search scheme for achieving high quality and fast performance. The project has a wide range of potential applications. In fact, the range of use of 3D high fidelity images in different businesses and fields is surprisingly broad, which suggests a wide range of possible commercial application. Many 3D-related businesses have significant presence in the UK, and are playing an active role in the global market, e.g. computer games, computer animation, broadcast television, mobile communication, web design, etc., all of which are facing demands for improved image quality to take full advantage of continual advances in display technology.

这个项目是调查的技术，使用纹理，以提高表面细节的显示在三维计算机生成的图像。人们普遍认为，真实的世界图像和计算机合成图像之间的主要区别之一在于高频可见表面细节的展示。本计画的主要目的是发展一种称为可放大双向纹理函数（ABTF）的关键技术。ABTF被设计用于在3D表面模型上生成纹理。与传统的纹理映射/合成技术相比，ABTF具有以下优点：1）它不会在特写视图中牺牲纹理质量; 2）它将准确地显示表面细节的显著视觉效果，包括自阴影和遮挡，相互反射和轮廓，在不同的观看/照明设置下。3）为了正确地合成和显示纹理，它将考虑目标表面曲率变化的影响。ABTF合成将基于混合图像建模和渲染方法。给定纹理样本的多个视图，它将恢复纹理的底层几何形状，并将它们用作目标表面的表面细节。为了达到高视觉保真度的目的，目标表面的颜色将通过快速搜索方案从多个视图的图像中获得，以实现高质量和快速性能。该项目具有广泛的潜在应用。事实上，3D高保真图像在不同行业和领域的使用范围惊人地广泛，这表明了广泛的商业应用。许多与3D相关的企业在英国有着重要的地位，并在全球市场上发挥着积极的作用，例如计算机游戏，计算机动画，广播电视，移动的通信，网页设计等，所有这些都面临着改善图像质量以充分利用显示技术的持续进步的需求。
