Paper Abstract
An imaging system’s spatial quality can be expressed by the system’s modulation spread function (MTF) as a function of
spatial frequency in terms of the linear response theory. Methods have been proposed to assess the MTF of an imaging
system using point, slit or edge techniques. The edge method is widely used for the low requirement of targets. However,
the traditional edge methods are limited by the edge angle. Besides, image noise will impair the measurement accuracy,
making the measurement result unstable. In this paper, a novel measurement method based on the support vector
machine (SVM) is proposed. Image patches with different edge angles and MTF levels are generated as the training set.
Parameters related with MTF and image structure are extracted from the edge images. Trained with image parameters
and the corresponding MTF, the SVM classifier can assess the MTF of any edge image. The result shows that the
proposed method has an excellent performance on measuring accuracy and stability.
