초록
A new approach is presented for estimating depths of defocused objects which are at distances by camera motions. An ordinary camera is used for obtaining defocused images in order to propose a coarse method with a potential. This method, therefore, requires only a few camera parameters, the amount of camera motions and defocused images that mean the sizes of defocused images in itself. We use the median filter as a fitting method for estimating depths of useful accuracy with relatively simple scheme. Experiments with real images show that depths of objects can be estimated concurrently although there are several objects in an image.
