This function estimates a depthmap and a reliability measure from defocused image sequences using shape-from-focus [1]. According to [2], depth for pixels with a reliability measure below 20 dB is not reliable and should be descarded. This code has been used in [2] and [3]. For a demo, just run 'sffdemo'
