Abstract :
In this paper, two video-signal processing methods are presented to realize real-time summing mode and subtraction mode ESPI. Besides, filtering, a novel “subtraction” approach by using a “summing” method is applied for more flexible subtraction. Both theoretical and experimental results are presented
