IMAGE NOISE REDUCTION THROUGH SPLINE SMOOTHING

Noise reduction is an essential part of image processing and there are many algorithms for the noise reduction process however, the common problem is that the noise reduction makes the contours unclear or leaves noise on the edges. All recording devices, both analog and digital have traits that make them susceptible to noise. Noise can be random or white noise with no coherent noise introduce by the device’s mechanism or processing algorithms. In this paper by spline smoothing we have tried to reduce image noise. By using this method we can minimize mean square error by determining the trade off values and weight coefficients for each line and pixel effectively.
