Video Enhancement Techniques

  • David G. Tieman


Image enhancement transforms an existing picture into a new picture that is suitable for a specific application. Enhancement is often used to make objects stand out from their background and become more detectable, as Fig. 13-1 illustrates. The object of enhancement is to increase the signal and decrease the noise. In many cases, the enhanced image is the desired end: the experimenter is seeking a “clean” picture to present to an intended audience. In other cases, the enhanced image is used for counting, measuring, or tracing the objects represented: the experimenter creates a simplified representation that eliminates the need for subjective judgments during analysis. Such simplified representations can facilitate analysis by inexperienced human observers or by computer.
