Abstract:
Since bokeh that means a blur or its shape is an attractive effect for generating natural images, various methods are proposed to syn- thesize bokeh by analyzing rays in the space domain [Cook et al. 1984]. Recently, based on fourier transform of light fields, a method that can treat real images is also proposed [Ng 2005]. However, it is not easy to capture wide and dense light fields in comparison with ordinary images. In this paper, we propose direct virtual bokeh gen- eration in the frequency domain from acquired multiple differently focused images without light fields or any depth estimation.
