Abstract:
1. A method of edge-adaptive interpolation and noise filtering an image, the method comprising: 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, wherein performing the secondary interpolation comprises: setting a filter based on the estimated edge direction and an edge frequency; and performing the secondary interpolation on the first color, based on the estimated edge direction, by applying the filter to the primary interpolated first color window.
