[Linux-Unix] Opencv_Mat DL : 0: 本文主要讲一些opencv 2.0版本后出现的Mat矩形类，主要是参考opencv自带doc文件夹下的tutiol教材。通过这次实验觉得用Mat的话下面几点需要特别注意（在代码中可以体现出来）：利用create函数重新改变Mat数据在内存中的布局。注意多通道数据在Mat中其实也是占一个元素的位置的。学会多维Mat的创建方法。当Mat矩阵比较小时，学会直接赋值的方法，即用Mat_。掌握Mat矩阵内容输出到终端时的几种常见格式。注意如果vector是单独一维的话需要转换成Mat才能输出，多维的可以直接输出，例如vector里面存放的是点的话。具体内容也可参考网站：http://www.cnblogs.com/tornadomeet/archive/2012/07/19/2599376.html-This article is mainly about some opencv 2.0 version of Mat rectangle class main reference opencv own doc folder under tutiol textbooks. Think through this experiment Mat, then the following points need special attention (reflected) in the code: create function to re-change the layout of the Mat data in memory. Attention to multi-channel data is actually accounted for the position of an element in Mat. Learn to create a method of multidimensional Mat. Mat Matrix comparison hours learn to direct assignment method, which uses Mat_. Grasp Mat matrix output to the terminal when several common formats. Note that if the vector is a single dimension needs to be converted into the Mat to output multidimensional can be output directly, such as vector stored inside the point.

[Linux-Unix] scan_img DL : 0: 本文来讲讲Mat存储的像素该怎么对其进行扫描？扫描的效率又如何？　　文章参考opencv自带的tutiol及其code。　　实验功能：　　可以手动选择打开电脑上的图片。　　对4种对Mat矩阵的扫描方法效率进行比较，这4种扫描方法分别为：连续内存直接访问；用迭代器进行访问；直接像素点进行访问；用LUT查找表进行访问；这4种扫描方法可以在菜单栏进行选择。　　这些访问完后是将每个访问到的像素点的像素进行压缩，压缩间隔可以在软件的界面中进行修改。　　软件的下端显示每种次扫描方法扫描打开的图片所用的平均时间(程序中设定为求100次的平均值)-This article Laijiang Jiang Mat stored in pixels how to scan them? Scan efficiency and how? The article reference the opencv comes tutiol its code. Experimental feature: you can manually choose to open the picture on the computer. Four kinds of scan efficiency matrix Mat these four kinds of scanning methods: continuous direct memory access access iterator direct pixel access access the LUT lookup table these four kinds of scanning methods select in the menu bar. Visit after each access to the pixels of the pixel to be compressed, compression interval can be modified in the software interface. The bottom of the software shows the average time used by each sub-scan method to scan to open the picture (the program is set to seek 100 times the average)

[Linux-Unix] mask DL : 0: 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.

[Linux-Unix] add_img DL : 0: 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.

[Linux-Unix] change_value DL : 0: 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.
