Description: QT4.5开发环境中编写的一个用来测试软键盘的程序。有两个LineEdit控件，一个旁边有一个按钮，点击按钮，自动弹出软键盘，输入后的数字直接显示在lineEdit1中，另一个实现，鼠标双击lineEdit控件，就自动弹出软键盘。该程序主要用在开发板程序开发过程中，因为有些开发板的环境下没有软键盘，没法输入数字，所以用这个测试程序中的方法可以直接在你需要弹出软键盘的地方，让它自动弹出软键盘，方便输入。-QT4.5 development environment used to test the preparation of a soft keyboard procedures. There are two control LineEdit, a next to a button, the click of a button, automatic pop-up soft keyboard, enter the number directly after the show in lineEdit1 Another realization of the mouse double-click lineEdit control, automatic pop-up on the soft keyboard. The program board in the development of the main development process, because some of the environment development board does not soft-keyboard, can not enter a number, so use this test procedure can be directly in the pop-up soft keyboard you need to place it automatic pop-up soft keyboard for input.

Description: 本文主要讲讲怎样对Mat矩阵进行mask操作，其实也就是对Mat矩阵的滤波操作，俗称卷积，参考文献为opencv自带的tutiol及其code.
开发环境：ubuntu12.04+opencv2.4.2+Qt4.8.2+QtCreator2.5.
实验功能：
单击Open image按钮，手动选择所需滤波的原图片。
单击Setting按钮，弹出对话框，选择滤波所用的模式，这里有2种模式，分别为自己实现滤波功能和采用opencv自带的滤波函数filter2D实现。
单击Process按钮，实现图片滤波过程，并将滤波结果显示在图片窗口中。
滤波完成后，图片下方法显示滤波所采用的模式及其花耗的时间。可以方便对2种模式的效率进行对比。
-In this paper, talk about how Mat Matrix mask operation is on the Mat matrix filtering operation, commonly known as the convolution the Reference opencv comes tutiol its code development environment: ubuntu12.04+opencv2.4.2+Qt4.8.2+QtCreator2 .5. experimental feature: click Open image button, manually select the desired filtering the original image. Click Setting button, pop-up dialog box, select the filter mode, where there are two kinds of mode, respectively, for their own filtering and adoption the opencv comes filtering function filter2D the Click the Process button, the image filtering process, and filter results are shown in the picture window. After the completion of the filter, under the picture display mode used by the filter and its time spent a. Can easily compare the efficiency of the two kinds of patterns.

Description: 本文主要讲的是怎样将2幅图片叠加，就像电影里面有时候出现的镜头一样，2幅图片可以按照不同比例重叠，当然这里主要是利用opencv自带的函数addWeighted().参考资料为opencv自带tutiol及其代码。
开发环境：ubuntu12.04+opencv2.4.2+Qt4.8.2+QtCreator2.5.
实验功能：
单击Open image1按钮，打开第1幅图片并在左边显示出来。
单击Open image2按钮，打开第2幅图片并在中间显示出来。
在Alpha栏输入第1幅图片在图片混合时所占的比例，这时Beta栏的值也会跟着改变，因为2着的比例之和为1.0.
同理，在Beta栏中输入第2幅图片在图片混合时所占的比例，这时Alpha栏里的值也会改变。
单击Add image按钮，在软件右边那栏可以看到图片混合的效果。-In this paper, is how to overlay the two pictures, like a film which sometimes appear in the lens, two images can overlap in different proportions, of course, mainly using the the the opencv own function addWeighted () reference materials for opencv comes tutiol its code. Development environment: ubuntu12.04+opencv2.4.2+Qt4.8.2+QtCreator2.5 experimental feature: Click Open image1 button, open an image and displayed on the left. Click Open image2 button to open the two pictures and show up in the middle. In the proportion of the alpha field, enter a picture in the picture is mixed, then the value of the Beta Bar will change with it, because 2 the proportion of 1.0. Similarly, enter two pictures in the Beta column proportion in the picture is mixed, this time Alpha column values will change. Click the Add image button in the software the right column you can see the picture mixed effect.

Description: 本文主要讲讲怎样改变图片的对比度和亮度，其实就是图片像素值线性变化了而已，对比度对应线性变化的系数，亮度对应其常量。参考资料为opencv自带tutiol及其code.
开发环境：ubuntu12.04+opencv2.4.2+Qt4.8.2+QtCreator2.5.
实验功能：
单击Open image按钮，在电脑中打开一张图片并显示出来。
拖动Contrast滑动条，改变对比度的值，可以看到对比度值的改变过程在滑动条下方显示，左边图片对应为其对比度改变后的效果。
拖动Brightness滑动条，改变亮度值，以看到亮度值的改变过程在滑动条下方显示，左边图片对应为其亮度改变后的效果。
点击Close按钮，退出程序。-In this paper, talk about how to change the contrast and brightness of the picture, in fact, the image pixel values linear change only, the contrast corresponds to the coefficient of linear change, the brightness corresponding constant. Reference to own tutiol its code opencv development environment: the ubuntu12.04+opencv2.4.2+Qt4.8.2+QtCreator2.5 experimental feature: click Open image button in the computer to open a picture and display it. Drag the Contrast slider to change the value of the contrast, you can see the contrast value of the process of change in the slider below the left picture corresponds to the effect of its contrast change. Drag the Brightness slider to change the brightness value, the slider below to see the changes in the brightness values in the left picture corresponds to its effect in the brightness changes. Click the Close button to exit the program.

Description: 基于Qt4下的截屏软件
使用了QPixmap::grabWindow(QApplication::desktop()->winId())来获得屏幕的图像
并保存在QPixmap的一个对象fullScreenMap里
再将该图像画到一个QWidget上并showFullScreen()以覆盖屏幕
之后的操作都是在这个QWidget上进行
跟QQ截图有点象
完成后点鼠标右键就有ContextMenu弹出
Esc为退出，空格键保存图像(当然也可以右键菜单保存)(Screen software based on Qt4
Using QPixmap:: grabWindow (QApplication:: desktop () ->winId ())) to get the image of the screen
And save it in an object fullScreenMap of the QPixmap
Then the image from a QWidget and showFullScreen () to cover the screen
The next operation is done on this QWidget
It's a bit like the QQ screenshot
After the completion of the right mouse button, there is a ContextMenu pop-up
Esc is the exit, the space key saves the image (and of course, it can be saved on the right menu))
