Estimation of System MTF of EO Satellite by Slanted Edge Method
نویسندگان
چکیده
Image Quality of spacecraft sensors vary between ground pre-launch measure, after launch and over satellite lifetime due to launching vibration and space harsh environment. Due to the inaccessibility of the satellite on orbit, it is mandatory to use indirect method in order to estimate satellite performances. The aim of this work is to estimate the Image Quality of satellite by using the sharp edge characteristics of image in order to obtain Image Quality parameter estimation such Modulation transfer function. The Edge based Selected Method is implemented and tested in view to learn more about its advantages and drawbacks. Key-Words: -MTF, ESF, Satellite, Slanted Edge, Satellite, LSF

Modified slanted-edge method and multidirectional modulation transfer function estimation.
The slanted-edge method specified in ISO Standard 12233, which measures the modulation transfer function (MTF) by analyzing an image of a slightly slanted knife-edge target, is not robust against noise because it takes the derivative of each data line in the edge-angle estimation. We propose here a modified method that estimates the edge angle by fitting a two-dimensional function to the image ...
متن کاملSlanted-Edge MTF for Digital Camera and Scanner Analysis
The development and adoption of standards for the evaluation of digital camera resolution has helped foster the widespread use of slanted-edge-based analysis. In addition, the form of these evaluation methods suggests their use in imaging system analysis and design. The standards-specific methods and algorithms, however, are not intended for direct MTF evaluation, but if care is taken to avoid ...
متن کاملFast MTF measurement of CMOS imagers using ISO 12233 slanted-edge methodology
The ISO 12233 standard provides a fast and efficient way of measuring Modulation Transfer Function (MTF) of digital input devices (such a digital still camera) using a normalized reflective target based on a slanted-edge method. A similar methodology has been applied for measuring MTF of CMOS image sensors, using 12233 slanted-edge technique associated with a prototype transmissive target. In o...
متن کاملFast MTF measurement of CMOS imagers at the chip level using ISO 12233 slanted-edge methodology
MTF measurement methods for imaging devices usually require the use of an optical system to project the image of the object onto the detector. So, MTF results quality strongly depends on the accuracy of the optical adjustments (alignments, focusing...). Dedicated edge patterns have been implemented at the chip level on a CMOS imager. One of them emulates the target used in the ISO 12233 slanted...
متن کاملEstimation Error in Image Quality Measurements
The development and adoption of standard image quality measurement and analysis methods have helped both the evaluation of competing imaging products and in technologies. Inherent in the interpretation of results from any particular evaluation, however, are the variation of the method itself, the sampling of test images, equipment, and test conditions. Here we take a statistical approach to mea...
