用牛顿迭代法求方程 f(x)=x³ -x² -1=0 在x。=1.5附近的一个实根。取§=0.000001，取最大迭代数为60. (With Newton iteration equation for f (x) = x ³-x ² -1 = 0 in x. = 1.5 near the root of a real. Take § = 0.000001, take the largest number of 60 iterations.)

In an image edge is more important to interpolate the missing pixel values. In similarity algorithm edge is detected using the unified high frequency map. Based on this the missing green pixels are interpolated by taking the average of surrounding values. Then the missing red and blue values are interpolated similarly.
