Description: 基于VS2008编写，程序很简单，算法很经典实用。提出一种基于三次拉格朗日插值的自适应图像缩放算法 该算法首先计算目标像素点周围三组源像素点的方差，选取方差最小的一组源像素点，然后采用三次拉格日插值公式求得目标像素点的灰度值实验结果表明，本文算法所得的目标图像边缘清晰，且算法复杂度较低，便于硬件实现，可以实现实时图像缩放。-Based on VS2008, the program has a very simple algorithm is very classic and practical. Traditional interpolation algorithm due to the low-pass filtering effect generally makes the target image edge blur, it is difficult to obtain satisfactory visual effects in order to achieve a better quality image scaling is proposed based on cubic Lagrange interpolation algorithm for adaptive image scaling algorithm that First calculate the target pixel set of source pixels around three variance, minimum variance select a set of source pixels, then the cubic Lagrange interpolation formula obtained target pixel gray value Experimental results show that the algorithm proceeds target image sharp edges, and the algorithm complexity is low, easy hardware implementation can achieve real-time image scaling.

Description: 本文以电场的三大定理、连续超张弛迭代算法、拉格朗日插值算法等原理知识作为理论基础，以 C 语言为编程工具，将由根据以上物理和数学原理所推导出来的模型转化为可以计算像管内电势的 CAD 程序软件。所编写的程序可以在给定像管参数和电极电位的情况下，计算圆柱形像管内任意一点的电位大小，并绘制出像管内的等势线；拉格朗日插值得到对称轴上任一点的电位值。 -In this paper, we base on the three theorems of the electric field, continuous ultra-relaxation iterative algorithm, and Lagrange interpolation algorithm. We use the C language as a programming tools, and transform the model derived above into a CAD software to calculate the electric potential in the image tube. In case the image tube parameters and electrode potential are known, the program written can get the potential of every point in the image tube, and plot equipotential lines inside the image tube. It can also get the potential of every point on the axis of symmetry by Lagrange interpolation. Platform: |

Description: In mathematics, bicubic interpolation is an extension of cubic interpolation for interpolating data points on a two dimensional regular grid. The interpolated surface is smoother than corresponding surfaces obtained by bilinear interpolation or nearest-neighbor interpolation. Bicubic interpolation can be accomplished using either Lagrange polynomials, cubic splines, or cubic convolution algorithm.
In image processing, bicubic interpolation is often chosen over bilinear interpolation or nearest neighbor in image resampling, when speed is not an issue. In contrast to bilinear interpolation, which only takes 4 pixels (2×2) into account, bicubic interpolation considers 16 pixels (4×4). Images resampled with bicubic interpolation are smoother and have fewer interpolation artifacts.
Suppose the function values f and the derivatives f_x, f_y and f_{xy} are known at the four corners (0,0), (1,0), (0,1), and (1,1) of the unit square. The interpolated surface can then be written Platform: |
