| Abstract(in English) | This paper presents a scale estimation algorithm based on Phase-Only Correlation (POC) for electron microscope images. The proposed method can estimate the scale factor and translational displacements between a reference image and an input image with high-accuracy. Significant improvement in scale estimation performance can be achieved by extracting a common region between the reference image and input image. Experimental evaluation using the Mandelbrot picture as a precisely scale-controlled image shows that the proposed method can estimate the scale factor in approximately 0.2[%]-scale accuracy, where the image size is 401×401[pixel], the scale factor is about 1000 and the scale is estimated with 16 stages (thus, the scale factor of each stage is about 1.54). This paper also describes an application of the proposed algorithm to magnification calibration for electron microscope images. |
