Edge-adaptive interpolation and noise filtering method, computer-readable recording medium, and portable terminal
摘要：
An edge-adaptive interpolation and noise filtering method is provided including performing primary interpolation on a first color, based on a first preset number of directions, with respect to a first color window obtained from an input image window, estimating an edge direction within a primary interpolated first color window obtained by the primary interpolation, based on a second preset number of directions, the second preset number of directions being larger than the first preset number, with respect to the primary interpolated first color window, performing secondary interpolation on the first color, based on the estimated edge direction, with respect to the primary interpolated first color window, and performing interpolation on a second color, based on the estimated edge direction, with respect to a second color window obtained from the input image window.
摘要（中）：

提供了一种边缘自适应内插和噪声滤波方法，包括：基于第一预设数量的方向，相对于从输入图像窗口获得的第一颜色窗口，对第一颜色执行主插值，估计主要内容中的边缘方向 基于相对于主内插第一颜色窗口的第二预设数量的方向，第二预定数量的方向大于第一预设数量的第一插值获得的内插第一颜色窗口，对第一颜色进行二次插值 基于估计边缘方向，相对于主内插第一颜色窗口，并且基于估计的边缘方向，相对于从输入图像窗口获得的第二颜色窗口，对第二颜色进行插值。
