Automatic exposure selection for High Dynamic Range photography

摘要: High Dynamic Range photography involves fusing bracket images taken at different exposure values in order to compensate for the low dynamic range of image sensors digital and smartphone cameras. Bracket normally consist an by auto-exposure setting a camera as well two other ±n where n is manually specified or selected. This paper discusses method automatically optimally select exposures using pixel clustering local entropy. The results obtained show that developed automatic selection provides more scene details compared manual fixed selection.
