Abstract :
In view of the low resolution and low contrast problems of B-mode ultrasonic echograms, this paper studies the wavelet method to solve the problems. Based on the multiscale singularity detection of 1-D signals, we present a multiscale interpolation method. Based on the multiscale singularity detection of 2-D signals, we present an edge and contrast enhancement method. The simulation results show that these methods ore helpful for improving ultrasonic echogram quality indeed
