Restoration of Color Images

Is it possible to mathematically estimate the original colors of an image when only limited color information and gray levels are present? How faithful is this estimate?

The answer is yes, it is possible — and with striking accuracy.

A new algorithm has been developed to restore color images when only a limited amount of the color data and the gray levels are available. Although previous experiments produced similar results, this new algorithmic method tends to more accurately reproduce the luminosity of the image. While the quality of the reconstruction increases with more correct color information, the way the color information is distributed is even more important. Read the rest of this entry »
