System for modifying lighting in photographs

摘要: A system for creating lighting a photograph generates large number ofmages based upon structures determined from the and randomly selected light positions, types directions. One or more photographs are analyzed to determine three-dimensional in photographs. These represented as gray surfaces, which is applied. The images culled provide set of best spans space by images. culling process iterative; at each iteration, image most dissimilar nearest neighbor added set. organized hierarchical structure. user interface allows review select combined create final with composite lighting. specifications can be saved future reference other applications. surface used modify intensity pixels order change photograph.
