摘要：

Two different interpolative schemes for adaptive contrast enhancement have been presented for speeding up the contrast enhancement algorithm proposed by Beghdadi and Negrate. To reduce the enhancement of noise in relatively flat regions present in the image, and adaptive power variation technique is used in which the degree of contrast enhancement is varied depending on the severity of brightness change in a region. A contrast transformation function is proposed which can be used for adaptive enhancement as well as de-enhancement of images.
