Abstract : Wireless Capsule Endoscopy (WCE) is considered as one of the non-intrusive diagnostic methods to explore diseases in the complete digestive tract without any discomfort or need for anodyne. To enhance the quality of diagnosis, some essential specifications of WCE such as video/image resolution, frame rate and transmission speed need to be refined. However these features demands more power. Existing capsule endoscopes are powered by button cell batteries and most of the power is utilized by video transmission which restricts obtaining quality video with better frame rate and better resolution. In order to overcome these issues many researchers proposed design of a low-complexity and low power video/image compression algorithms that produces higher frame rate with better quality, lower bandwidth and transmission power. This paper summarizes the existing image and video compression methods for WCE, with a significant focus on understanding their design and architecture in-terms of complexity, memory, power and diagnostic yield.
