Abstract:
To raise the resolution of the image, this paper presents an improved Adaptive Morphologic Motion Compensation(AMMC) de-interlacing algorithm. It is based on reversibility of wavelet transform to employ the wavelet transform for the post-processing stage. It preserves the edge, and reduces the interpolation error of the motion compensation by using the spatial-temporal correlation and weighting the wavelet coefficients. Experimental results show that the algorithm can reduce the ambiguity of the image edge, and accomplish the better image quality.
