Sensor Noise Assessment Approach in a Patterned Region

摘要: In this paper, we propose a simple noise assessment approach for sensors. We assume the input signal is contaminated by white additive and zero mean Gaussian which. To measure level, intensity-homogeneous blocks are found first, then evaluate variance in blocks. determined blocks, use high pass filter. Experimental results show that presented method provides good performance natural artificial images over large range of levels.
