Artem V. Nikonorov, Sergey Alekseyevich Bibikov, Vladimir Alekseyevich Fursov · 2010
The paper deals with information technology for correction of shadow artifacts on color digital images obtained by photographing of paintings with the purpose of their reproduction. Shadow artifacts are caused by differences of light intensity. The problem of shadow detection and subsequent color correction is solved. The architecture of heterogeneous CPU/GPU - system implementing the elaborated technology is considered, examples of real images processing are given.
