A hybrid Super Resolution (SR) algorithm is proposed to deal with the Low Resolution (LR) images degraded by Mixed (Gaussian + Impulse) noise.The algorithm adaptively estimates and removes the impulse noise from the input LR images based on edge, geometrical & size characteristics.The fuzzy based impulse noise removal algorithm is along with adaptive sharpening filter based SR using steering kernel regression are used to obtain a HR image.The experimental results confirm the efficacy of the algorithm for different types of images at various noise densities.
