Description: 本实验是一个采用基于像素复制的方式来进行图像缩放的程序，它分别由两个小程序组成，图像缩小和图像放大，程序的输入为一个图像矩阵和缩放因子（为整数）。图像的缩放是对图像进行的一种几何变换，通过对图像对应矩阵得操作来实现对图像大小的改变。像素复制方法的图像缩放的原理主要是对原来输入图像的整行或是整列像素进行简单的复制与删除，达到改变图像的大小的目的，-Used in this experiment is a pixel-based approach to copy image scaling procedures, which were composed by the two small programs, images shrink and enlarge images, the program input for an image matrix and scaling factor (an integer). Image scaling is a geometric image transformation, through the image corresponds to a matrix operation to achieve a change of image size. Pixel of the image scaling method to copy the principle is the original input image of the entire line out or the entire pixel simple copy and delete, to change the image size of the purpose of Platform: |

Description: HU不变矩程序代码很多，但是没找到一个完整准确的代码。本人对其中的某些代码修正后，和matlab计算结果进行比较，结果是一致的。本程序没有利用Opencv计算Hu矩的函数，好像opencv计算的M03和M30应该对调，否则，和matlab计算不一样！对旋转、缩放的图像进行测试，HU矩也是一样的，不信可以利用提供的图片对比一下。由于HU矩比较小，程序对HU矩取对数便于查看比较。总之，程序绝对安全可靠，可直接调用。-HU moment invariants code a lot, but could not find a complete and accurate code. I am, some of which code amendments, and matlab calculation results are compared, the result is the same. This procedure did not take advantage Opencv a function of the calculation Hu moments, like the M03 and M30 calculate opencv should be reversed, otherwise, and not the same as matlab calculations! Right rotation, scaling the image to test, HU is the same moment, and you do not believe you can compare the use of the images. HU moment due to a relatively small program HU moment logarithmic relatively easy to see. In short, the program is absolutely safe and reliable, can be directly invoked. Platform: |

Description: 实现一个图像缩放算法，不调用对算法本身有帮助的库函数，将图像缩放到指定的大小。
具体功能：
1.输入为用windows画图程序生成的无压缩BMP图片，只支持256色位图和24位色位图，输出格式与输入格式相同，要求也要能用Windows画图程序打开；
2.支持批量转换，一次转换的张数不作限制，命令行接口指令如下：
Zoom.Exe imagelist.txt
其中imagelist.txt的保持待转换的文件列表，以纯文本格式指定了每幅图片转换后的宽度和高度，格式示例如下：
Image1.bmp 320,240
Image2.bmp 320,240
程序使用说明：
1、将Mindray.exe、imagelist.txt和用于缩放的位图文件放在相同目录下；
2、在运行窗口中输入“cmd”进入cmd.exe
3、输入Mindray.exe所在路径，例如“e:”
4、输入指定格式命令行：Mindray.exe 1.txt执行程序，得到处理结果。

2 supports batch conversion, a conversion of the number of sheets without limit, the command line interface command is as follows:
Zoom.Exe imagelist.txt
One imagelist.txt to maintain a list of files to be converted to plain text format conversion is specified after each image width and height, format example:
Image1.bmp 320,240
Image2.bmp 320,240

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: 数字图像处理：（1）输入图像，采用半色调技术并将图像打印和显示。（2）按要求降低图像的灰度级。（3）采用像素复制的方法对图像进行缩放。（4）采用双线性插值法的方法对图像进行缩放。-Image Printing Program Based on Halftoning The following figure shows ten shades of gray approximated by dot patterns. Each gray level is represented by a 3 x 3 pattern of black and white dots. A 3 x 3 area full of black dots is the approximation to gray-level black, or 0. Similarly, a 3 x 3 area of white dots represents gray level 9, or white. The other dot patterns are approximations to gray levels in between these two extremes. A gray-level printing scheme based on dots patterns such as these is called halftoning. Note that each pixel in an input image will correspond to 3 x 3 pixels on the printed image, so spatial resolution will be reduced to 33 of the original in both the vertical and horizontal direction. Size scaling as required in (a) may further reduce resolution, depending on the size of the input image. (a) Write a halftoning computer program for printing gray-scale images based on the dot patterns just discussed. Your program must be able to scale the size of Platform: |
