Estimating reflectance from multispectral camera responses based on partial least-squares regression
14 years 6 months ago
Abstract. In multispectral imaging systems, the accuracy of reflectance estimation can be degraded by the nonlinearity in imaging process, which is due to non-Gaussian distribution...
