Abstract:
The general theories of gray correction methods for the medical ultrasonic image are introduced in this paper, including gray level correction, gray level transformation and histogram correction. The dominant histogram equalization method is expatiated and modified against its disadvantages including inapparent enhancement of partial detail and non-interactivity. Series connections of several gray correction methods are used to treat with the ultrasonic image, and thus its utility is improved through the selective enhancement of the contrast of certain gray scope.
