One significant problem in texture synthesis based on ω-tile is that it is not suitable for the synthesis of structural texture. In this paper, we propose a robust approach that can generate an ω-tile set of high-quality regular texture. First, all possible sets of 4, 8 and 16 ω-tiles that meet certain criteria are obtained, and then a fast search algorithm is raised to choose the optimal cutting...
This paper presents an efficient motion adaptive de-interlacing technique that consists of two main steps, i.e. 4-field extended Gaussian filtering motion detection and adjustable window ELA de-interlacing. Four consecutive interlaced fields are used to detect motion accurately. With a Gaussian filter, the motion detection can eliminate the influence of noise. An adjustable window ELA de-interlacing...
