Abstract

Digital cameras often suffer from limited depth-of-field which results in blurring parts of the captured image. While, in some applications, partial blurring of the scene might be desired, capturing all-in-focus images is usually of main interest. In this paper we describe a method for multi-focus image fusion able to provide a sharp image from a set of several images captured with different focus settings. Our proposed method is presented in detail and experimental results are shown comparing our approach with other similar methods from the open literature in terms of processing time, visual quality and root mean squared error.
