Abstract

Traditional sensors and systems for wrist pulse acquisition, known as inconvenient, contact, depends on the digital and analog circuits. In this paper, a method in video motion processing at one-demensional signal extraction and analysis is proposed. It can be applied for wrist pulse acquisition and based on subtle video motion amplification algorithm. This is the demostraction of a low-cost (only need ordinary camera on the cell phone), accurate method for cantact-free wrist pulse acquiring that is capable of performing measurements in different illumination conditions. As the ultimate recovered single and all periodic pulse signal shown, it can be demonstracted that the proposed method can get accurate pulse signal compared to traditional methods.
