A generalized framework for numerical differentiation (ND) is proposed for constructing a finite impulse response (FIR) filter in closed form. The framework regulates the frequency response of ND filters for arbitrary derivative-order and cutoff frequency selected parameters relying on interpolating power polynomials and maximally flat design techniques. Compared with the state-of-the-art solutions,...
This paper presents a new technique of hidden Markov model (HMM) for video deinterlacing. Existing deinterlacing algorithms estimate missing pixels of an absent row in an interlaced frame on a sample-by-sample basis. In contrast, the proposed HMM-based deinterlacing technique adopts an approach of sequence estimation and makes a joint decision on the row of missing pixels as a whole. This allows a...
We propose a fast adaptive image interpolation method for still color images which is suitable for real-time applications. The proposed interpolation scheme combines the speed of fast linear image interpolators with advantages of an edge-guided interpolator. A fast and high performance image interpolation technique is proposed to interpolate the luminance channel of low-resolution color images. Since...
