光學遙測系統被應用在衛星上來記錄由地球表面反射光的強度。一般而言，衛星影像為了提升影像的品質，因此進一步的數位影像處理是有其必要的。對於每一顆衛星而言，去除雜訊的方法是基於衛星本身的感測器的特性。此外，反迴旋運算演算法是一種知名的演算法用於提升影像細節的表現。在這個簡報中，我們會以衛星影像為例來介紹除噪的演算法與反迴旋運算演算法。

Remote Sensing Instrument is an optical instrument to measure the reflected radiant energy from earth’s surface. In general, the satellite image needs further steps of digital image processing for enhancing the image quality. For each satellite, the de-noise processing is based on characteristic of satellite sensor. Moreover, the deconvolution processing is a well-known technique to improve the detail performance. In this presentation, we will use the satellite image as an example to introduce the de-noise and deconvolution processing.
