	On orbit MTF measurement of remote sensing camera based on wavelet transform (EI CONFERENCE) 会议论文 OAI收割 ICO20: Remote Sensing and Infrared Devices and Systems, August 21, 2005 - August 26, 2005, Changchun, China 作者: Wang X.; Wang X.; Wang X. 收藏 \| 浏览/下载：27/0 \| 提交时间：2013/03/25 High resolution remote sensing images are often applied in many research fields. But there are less research on images quality for an orbit remote sensing camera. The magnitude of the OTF as the modulation transfer function (MTF) is a measure of the 2-D spatial frequency response of the remote sensing camera. In this paper knife-edge technique based on quadratic spline wavelet fast transform algorithm is proposed and applied to generate MTF with a greatly high resolution in horizontal or vertical direction. The result has fully demonstrate the potential applicability and good property of the method to estimate MTF for remote sensing camera.
