DCT变换1、 提取彩色图像,将图像大小限制为512*512*3;
2、 提取彩色图像三个颜色分量的矩阵,每个矩阵单独处理;
3、 将矩阵分为8*8的块,做DCT变换;
4、 提取每个块的一部分DCT系数做IDCT变换,显示基本图像;
5、 再提取每个块的一部分DCT系数做DCT反变换,得到增强层1,与前一次得到的数据叠加,得到质量更好的图像。

三次样条插值函数边界条件由实际问题对三次样条插值在端点的状态要求给出.以第1边界条件为例,用节点处二阶导数表示三次样条插值函数,用追赶法求解相关方程组.通过Matlab编制三次样条函数的通用程序,可直接显示各区间段三次样条函数体表达式,计算出已给点插值并显示各区间分段曲线图.(Cubic spline interpolation function from the real problems of boundary conditions cubic spline interpolation is required to give the state of the endpoint. Boundary conditions in the first example, the second derivative with node represents a cubic spline interpolation function, solving equations associated with catch-up method group. preparation of common procedures cubic spline function through Matlab, can directly display each range segment cubic spline function body expression, to the point of interpolation has been calculated and displayed for each sub-interval graphs.)
