Focusness Evaluation for Digital Refocusing Light Field Photography
The focusness detection methods for digital refocusing both in spatial and frequency domain are presented.The spatial method reduces the data used in image reconstruction according to the selected evaluation area.And the frequency domain method embeds the evaluation functions in image reconstruction.The experimental results show that the improved methods are faster than the conventional.
