A method for segmentation of images is introduced, and a technique for detecting ellipses in the regions is discussed. The former is based on iteratively dividing a histogram into some modes in taking account of a measure for adjacent separability. The latter consists of classifying behavior of parameters in a quadratic equation obtained by using a recursive least-squares estimator. Some experimental results for applying these methods to machine parts are shown.
