Abstract: We introduce a new method that can automatically determine regions of focus within an image. The focus is determined by generating Content-Driven Superpixels and subsequently exploiting consistency properties of scale-space. These superpixels can be analysed to produce the focal image regions. In our new analysis, Light-Field Photography provides an efficient method to test our algorithm in a controlled manner. An image taken with a light-field camera can be viewed from different perspectives and focal planes, and so by manually modifying the focal plane we can determine if the extracted focal areas are correctly extracted. We show improved results of our new approach compared with some prior techniques and demonstrate the advantages that our new approach can accrue.
