The following equation will take the coordinates of a set of pixels as (x,y) pairs and find a line that fits those points (n = number of points). The equation of that line is going to be y = a + bx, where a is the intercept, and b is the slope. As part of the calculations...

The linear equation Ax = b, with A an n × n matrix and b an n × l matrix over a unique factorization domain R, is related to the controllability submodule U of the pair (A, b). It is shown that the above equation has a solution lying in V if, and only if, A is ...

We consider the linear matrix equation AX+YB=C where A,B, and C are given matrices of dimensions (r+1)×r, s×(s+1), and (r+1)×(s+1), respectively, and rank A = r, rank B = s. We give a connection between the least-squares solution and the solution which minimizes an ...

回顾一下我们要做的事情:找一组A、B、C、D的值,使得公式(1)的形状尽可能与美术调整的离线S形曲线形状尽可能一样。这个事情可以转化成一个最优化问题进行求解,也就是说对于离线S形曲线中在有效值域区间的曲线上的任意点,拟合式的值都应该等于或者尽可能接近0。到了这里,我们就可以用最小二乘法的相关知识解决...
