Design and Implementation of a Very Low Cost Surveillance System

Abstract

Block truncation coding is an image compression algorithm that has lower efficiency in compare with some other algorithms, but also has low cost and complexity. FPGAs are used for implementing fast digital systems, but they have more cost. In this paper, a surveillance system is designed and implemented based on the BTC image compression algorithm using some parallel microcontrollers that has very low cost and suitable speed.
