Abstract : The aim of image synthesis is to compute realistic views of a three-dimensional scene, defined by a geometric 3D model. Modeling is a manual task, and may need several man-months for a realistic and complex scene, as a landscape. We propose to automate this task. A few photographs of the landscape are enough to entirely model its geometrical and photometric information: 3D structure, colors and textures. Therefore, using image analysis and computer vision techniques, we can automatically generate a three-dimensional representation of the scene, and view it under any angle. Appropriate algorithms are evaluated and specifically adapted to our problem. Detailed quantitative tests are led on both synthetic and real data, and the final quality of the computed images is numerically evaluated.
