System object: vision.GammaCorrector
Package: vision

Apply or remove gamma correction from input


Y = step(H,X)


Y = step(H,X) applies or removes gamma correction from input X and returns the gamma corrected or linearized output Y.

    Note:   H specifies the System object™ on which to run this step method.

    The object performs an initialization the first time the step method is executed. This initialization locks nontunable properties and input specifications, such as dimensions, complexity, and data type of the input data. If you change a nontunable property or an input specification, the System object issues an error. To change nontunable properties or inputs, you must first call the release method to unlock the object.
