Low Power Compression Algortihm for Wireless Capsule Endoscopy

Wireless-capsule-endoscopy (WCE) is a state-of-the-art technology to receive images of human intestine for medical diagnostics. In WCE, the patient ingests a specially designed electronic capsule which has imaging and wireless transmission capabilities inside it. While the capsule travels through the gastrointestinal (GI) tract, it captures images and sends them wirelessly to an outside data recorder unit. The data recorder stores the images and later the data is transferred to another platform (i.e., personal computer (PC), diagnostics machine, etc.) where the images are reconstructed and displayed for medical diagnosis. The capsule runs on button batteries that need to supply power for about 8-10 hours. The key design challenge in capsule endoscopic system is to reduce the area and power consumption of the capsule while maintaining acceptable video quality. In this work, a novel and low-complexity image compression algorithm tailored for endoscopic images is presented
