Description: 数字图像放大缩小及旋转计算组间方差和组内方差的时候调用了一个函数专门求阈值，可能这里的计算还是有一点问题。而且在我的函数里，要256次调用这个函数，又因为计算机是按字节处理数据的，因此写图像数据的时候要用每8个写到一个数组中，然后通过计算得到字节类型的值，这些都使得我的算法效率比较低，最后一个问题，我觉得如果使用位运算会快一些，但是前面的问题还没有想到比较好的解决方法。-Digital Image zoom and rotation calculation of variances and group between the two groups when the variance of a function call seeking specific threshold, the calculation may be here, or there was a problem. And in my function, it is necessary 256 calls to this function, and also because the computer is processing data in bytes, and therefore the time to write image data to use for every 8 write an array, and then calculated byte type values, which are made to my algorithm' s efficiency is relatively low, the last issue, I think that if you use bit computing will be faster, but the previous issues have not yet thought of a better solution.

Description: 用于从一个IplImage对象或者BYTE型数组中取出一幅图像的子图像，类似于OpenCV中的SetImageROI，但是该函数提供的功能是原图像子图像的一个拷贝，而非在原图像中设置ROI。-For the IplImage from a BYTE array object or remove an image of the sub-image, similar to OpenCV' s SetImageROI, but the function is the function of the original image to provide the child a copy of the image, rather than set in the original image ROI.

Description: 本实例企业员工IC卡考勤系统用到了IC卡自带的Mwic_32.dll组件，运行前，需将该组件拷贝到Debug文件夹中。可由此开发一个为企业内部员工IC卡考勤的程序，。通过这个源码你还可以学习如何使用和声明动态链接库，设置的一个变量，用于控制一张IC卡只读取一次以及向数据库中只添加一次内容，向IC卡中写数据，读取IC卡中数据，核对卡密码，调用公共类中的ReadIC方法开始循环读取IC卡，端口初始化，设备密码格式，将数据库中的图片转换成二进制流，将字节数组存入到二进制流中，将图片存入到指定的路径等，请注意，IC卡的密码默认为6个F（密码为：ffffff），，作者拥有版权，仅供学习与参考。-Employee IC card attendance system example of the enterprise use the Mwic_32.dll components, IC card comes before the operation, the components are copied to the Debug folder. Thus the development of a for internal staff of IC card program,. Through this source code you can learn how to use and statement of dynamic link library, a variable is set, for the control of an IC card is read only once and only add a content to a database, and write data to the IC card, IC card data read, check card password, the ReadIC method is called public class start loop to read the IC card, port initialization, device password format, the database of images into binary stream, converts a byte array into a binary stream, the image stored in the specified path, please note, the IC card password default to 6 F (Code: ffffff), author, copyright, only to learn with reference to.

Description: Bitmap是VB.NET和C#中处理图像的基础类，用于处理由像素数据定义的图像的对象。 存储灰度图像数据，一维数组存储。对于8位图像，一个像素即是一个字节。每行存储的字节数必须是4的整倍数，需要时添加适当字节。-Bitmap is VB.NET and C# base class in the image processing for processing an image defined by pixel data of the object. Grayscale image data storage, one-dimensional array storage. For 8-bit image, a pixel that is a byte. The number of bytes stored in each row must be an integral multiple of 4, when required to add the appropriate bytes. Platform: |

Description: stm32数组转二进制工具，在Keil下运行
1.输入文件内容必须包含类似于{0xff,0xff}这样的c语言数组格式，才能正常转换。大括号和前导符“x”是必须的。
2.支持8位和16位数据。
3.支持4个字节的长宽信息，方便Image2Lcd程序输出的图片转换成Bin。
4.支持成对“/”符号包含注释信息，若文件内容只有单个“/”,后果自负。
5.支持头四个字节的宽高信息互换存储位置。-stm32 array to binary tools, running in Keil
1 input file must contain similar {0xff, 0xff} c language such array format to normal conversion. Braces and leading character "x" is a must.
2 supports 8-bit and 16-bit data.
3 supports 4-byte length and width information to facilitate Image2Lcd program output image into Bin.
4 support paired "/" symbol contains annotation information, if only a single file contents "/" peril.
5 support the first four bytes wide exchange of information stored in a high position. Platform: |
