Colorization is a technique to produce color components for grayscale images with color assigned information provided by the user. The conventional method colorizes via propagating the assignations with weights of neighborhood pixels. In this paper, we propose the colorization method based on the piecewise auto-regressive (AR) model. The proposed method calculates weights considering taking account...
A new demosaicking algorithm based on direction categorization for wireless IP camera is proposed. By calculating the differences of neighboring pixels and the difference of average value of horizontal and vertical green pixels, the centered pixel is classified as horizontals verticals smooth and non-direction. After the directionality of the centered pixel is determined, the gradients of adjacent...
