Shadow and Highlight Enhancement - Automatic Shadow Recovery Methods

Automatic Shadow Recovery Methods

There exist a number of automatic computer image processing-based shadow recovery and dynamic range compression methods that yield a similar effect. Some of these methods include the retinex method and homomorphic range compression. The retinex method is based on work from 1963 by Edwin Land, the founder of Polaroid.

Shadow enhancement can also be accomplished using adaptive image processing algorithms such as adaptive histogram equalization or contrast limiting adaptive histogram equalization (CLAHE).

Famous quotes containing the words automatic, shadow, recovery and/or methods:

    Predictions of the future are never anything but projections of present automatic processes and procedures, that is, of occurrences that are likely to come to pass if men do not act and if nothing unexpected happens; every action, for better or worse, and every accident necessarily destroys the whole pattern in whose frame the prediction moves and where it finds its evidence.
    Hannah Arendt (1906–1975)

    And the raven, never flitting, still is sitting, still is sitting
    On the pallid bust of Pallas just above my chamber door;
    And his eyes have all the seeming of a demon’s that is dreaming,
    And the lamp-light o’er him streaming throws his shadow on the
    floor;
    And my soul from out that shadow that lies floating on the floor
    Shall be lifted—nevermore!
    Edgar Allan Poe (1809–1849)

    It’s even pleasant to be sick when you know that there are people who await your recovery as they might await a holiday.
    Anton Pavlovich Chekhov (1860–1904)

    Crime is terribly revealing. Try and vary your methods as you will, your tastes, your habits, your attitude of mind, and your soul is revealed by your actions.
    Agatha Christie (1891–1976)
