Abstract(in English)	A method of pattern matching using logarithm converted autocorrelation on Radon transform (LACR) is proposed. The LACR is invariable even if objects are translated in a picture. In the case of object scaling and rotation, the LACR is merely translated. Moreover, autocorrelation on the LACR with some regularization become invariable in object scaling, translation, and rotation. We identify objects with their autocorrelation on the LACR, and estimate the difference of size, rotation angle, and position of two objects using phase only correlation. We execute simulations of the pattern matching using test images.
