Temporal Image Normalization TIN is defined as a process which removes most effects of sun angle, look angle, and atmosphere from temporally separated images of the same area. This process is usually used to prepare images for further analysis. Three approaches are used in the TIN are 1 analysis of image and scene content techniques come from the fields of photographic science and photometry, 2 analysis of atmospheric and ephermeris data techniques come from meteorological theory and usually require extensive measurements of the atmosphere, and 3 combinations of approaches 1 and 2. Five TIN algorithms are discussed and three of them are evaluated in this paper according to the quality of their output images and the degree of normalization achieved. Author
