Abstract

We need accurate zoom ratios between a base frame and other frames for resolution enhancements using plural images in zoom sequences. In this report, we show the problem of the existing zoom ratio estimation methods. Next, we show a new estimation method to decrease the error of the accumulated zoom ratio by estimating zoom ratio between observation frames and panoramic images pasted according to the zoom ratio, and we show experimental result of zoom ratio estimations using the proposed method. Then, we show the method and these experimental results of estimating the high resolution image using the estimation zoom ratio.
