A new method of super-cooled water recognition in dew point hygrometer by morphology-based image processing

This paper presents a new method of super-cooled water recognition in dew point hygrometers. The developed method is based on morphological analysis of the hygrometer detector (semiconductor mirror) image. This method of great efficiency (some 96%) is universal and can be applied to hygrometers of either copper or semiconductor mirror for automatic correction of the measurement error.
