CMOS sensor cross-talk compensation for digital cameras

This paper presents two algorithms for removing the crosstalk effect in CMOS sensor based color-imaging systems. The algorithms work on the Bayer raw data and have low computational complexity. Experimental results on Macbeth color chart and real images demonstrates that both algorithms can effectively eliminate the crosstalk effect and produce better quality images with conventional color interpolation and correction algorithms designed for CCD image sensors. Complexity of the algorithms is also analyzed.
