Abstract
In this thesis, we introduce and present a solution to the lighting-by-guide problem:iven the description of a scene and an image as the lighting guide, automatically find a lighting configuration so that the resulted rendering best matches the lighting guide.ur solution framework consists of four main modules, initial guess, optimization, relighting, and difference metric evaluation.ince the resulted problem is a high-dimensional nonlinear optimization problem, it is crucial to have a good initial guess.e propose an efficient and effective algorithm for this task.xperiments show that our system can produce good quality lighting setups.he result is an automatic lighting algorithm which infers the lighting configuration from the lighting guide, greatly alleviating lighting artists'' workload.
