Defective Target Detection by Ultrasonic Image Using Multifractal Geometry

In ultrasonic imaging system, the system to distinguish objects from measurements of their pulse backscatter signals is a topic of considerable investigation. Current nondestructive detection, it encounter difficulty in identifying small pieces of defect, these targets hard to recognize because targets signal have to compete with other clutter signals. Therefore to improve the performance of image for applying multifractal geometry, we must first gain a understanding of the characteristics of image clutters.
