\section{Conclusion\label{sec:conclusion}}

In this paper we present the design to reduce the data size of a two dimension thermal image. By using the property that thermal image is gray scale and nearby pixels are have similar value, we can use the average value to stand for whole region. By giving every regions different resolutions, we can reduce the file size to $50\%$ less than JPEG when there is $0.5\%$ of distortion, and up to $93\%$ less when there is $2\%$ of distortion.
