Abstract
We propose a fast estimation algorithm for calculation of a reflectance
map from measured radiances based on Wiener estimation technique. This
technique uses many sample data of reflectance maps to decide transformation
for accurate estimation. Reflectance maps of objects are estimated rapidly
by linear operation between a vector of measured radiances and an estimation
matrix previously calculated based on the sample data.
