This model can then be transferred to other objects, allowing a non-expert user to insert a synthetic object into a real video sequence so that its appearance matches that of an existing object, and changes appropriately throughout the sequence. As the method does not require any prior knowledge about the scene, the lighting conditions, or the camera, it is applicable to video which was not captured with this purpose in mind. However, this lack of prior knowledge precludes the recovery of separate lighting and surface reflectance information. The SecondSkin appearance model therefore combines these factors. The appearance model does require a dominant light-source direction, which we estimate via a novel process involving a small amount of user interaction. The resulting model estimate provides exactly the information required to transfer the appearance of the original object to new geometry composited into the same video sequence.en(c) 2009 The Author(s) Journal compilation (c) 2009 The Eurographics Association and Blackwell Publishing Ltd.I.3.6 [Computer Graphics]: Methodolgy and TechniquesComputing MethodologiesI.4.8 [Image Processing and Computer Vision]: Scene AnalysisShadingJournal article002009300610.1111/j.1467-8659.2009.01550.x0002707781000012-s2.0-7194910253337286Van Den Hengel, A.
