Abstract: A method of generating a value for a missing pixel nullxnull by determining a nullleast harmfulnull local edge direction between pixels, or sub-pixels, on substantially opposing sides of the missing pixel, and interpolating the difference to arrive at a value for pixel nullxnull. The method involves generating sub-pixel values for locations within neighboring pixels, the sub-pixels may comprise half-pixels, quarter-pixels, three-quarter pixels, and so forth, wherein any fractional pixel quantity may be created. Absolute difference values are calculated between neighboring pixels, or sub-pixel values, to determine a least harmful local edge direction along which a value is generated for pixel nullxnull by interpolation.

Abstract translation: 通过在缺失像素的基本相对的侧面上确定像素或子像素之间的“最不利的”局部边缘方向来产生缺失像素“x”的值的方法，并且内插差值以得到 像素“x”。 该方法涉及为相邻像素内的位置生成子像素值，子像素可以包括半像素，四分之一像素，四分之三像素等，其中可以创建任何分数像素数量。 在相邻像素或子像素值之间计算绝对差值，以确定通过插值为像素“x”生成值的最不利的局部边缘方向。
