ABSTRACT:
Methods and apparatus implementing systems and techniques for adjusting images. In general, in one implementation, the technique includes: receiving input defining an adjustment to be applied to a differential representation of a source image, calculating the differential representation of the source image, producing a structural representation of the source image, the structural representation corresponding to multiple types of contrast in the source image, modifying the differential representation based on the structural representation and the input defining the adjustment, and generating a modified image from the modified differential representation by solving a Poisson differential equation.
