We present a method to measure reflectance and texture of surfaces in a one step process. For later use in digital image synthesis it is mandatory to separate the gathered intensi...

Image denoising algorithms often assume an additive white Gaussian noise (AWGN) process that is independent of the actual RGB values. Such approaches cannot effectively remove colo...

In [1], a novel method for identifying the source camera of a digital image is proposed. The method is based on first extracting imaging sensor’s pattern noise from many images...
