| Resumo: | As guest editors, we are proud to present the seven papers contained in this issue of The Visual Computer.The related topics range from high dynamic range imaging, to inverse tone mapping, rendering, polygon visibility and animation. The first paper, “Spatially varying image based lighting by light probe sequences: capture, processing and rendering” presents a novel technique for capturing spatially or temporally resolved light probe sequences, which can then be used for image based lighting. It is an extended version of the Best Paper Award winner submission that the authors presented last year at ACM GRAPHITE. Still related to HDR, the paper “A framework for inverse tone mapping” tackles the problem of extending the dynamic range of current single exposure, low dynamic range images, by finding the areas considered to be of high luminance and then building an expand map based on density estimation.
