Abstract This paper presents a spatial noise reduction technique designed to work on CFA Color Filtering Array data acquired by CCD-CMOS image sensors. The overall processing preserves image details using some heuristics related to the HVS Human Visual System; estimates of local texture degree and noise levels are computed to regulate the filter smoothing capability. Experimental results confirm the effectiveness of the proposed technique. The method is also suitable for implementation in low power mobile devices with imaging capabilities such as camera phones and PDAs. View Full-Text
