Grayscale-conversion
- 利用OpenCV载入工程文件夹中的彩色图像,进行灰度转换,并将转换前后的两张图片同时显示出来。-Load color images in the project folder using OpenCV and make the grayscale conversion, then show the two pictures.
Sobel-Laplace-Canny-matlab-code
- 模式识别大作业题目和实习代码: (1)请自己在互联网上任意找一张图片用做测试,命名为“学号后四_Original”。放在C++工程文件夹下(与CPP文件放在同一文件夹)。用C++调用OpenCV函数对该幅图片进行读入和显示操作。 (2)在(1)基础上,添加修改代码,将原图转换成灰度图像,并保存,命名为“学号后四位_Gray”。 (3) 请利用OpenCV中Sobel,Laplace,Canny算法相应函数对(2)中图像进行处理,并保存,命名为“学号后四位_Sobel”或“学号后四位_

- 本代码用于角点检测,先将图片转换成灰度图,然后对灰度图进行角点检测,并且标出检测出的角点-The code for corner detection, the first image into grayscale, and then the corner detection of grayscale, and marked the corners detected
showimage
- 调用opencv中的相关库函数,将一张彩色图转换为其对应的灰度图,并显示原彩色图和操作后的灰度图-Through calling the functions of opencv, change a colorful image to its gray image, and show the original image and the gray image.
huiduzhuanhuan
- 本程序在Visual C++平台上使用OpenCV中的函数来实现图像灰度转换。解压后的文件夹可以在VC上直接运行。-OpenCV function to achieve the image grayscale conversion program in Visual C++ platform. After extracting the folder can be run directly on the VC.
Task_01
- 读入一段视频并将之分解成每帧,然后进行灰度转换-Read into the section of video and broken down into frames, then the gray scale conversion
GetSubImagebyopencv
- 前段时间在OPENCV中做一个小东西,使用到子图像的提取和拷贝,一时间没有找到好的方法,要么直接访问像素进行赋值,要么通过数组来转换,总是感觉别扭,后来终于弄清了一个比较简单的方法,需要利用一下OPENCV中的ROI方法,该方法对于任何格式的灰度或者彩色图像均适用-Do a small thing, some time ago in the OPENCV in sub-images used to extract and copy, for a time did not find a good
opencv_dft
- 本文主要介绍怎样使用opencv来对图片进行傅里叶变换,其核心函数是opencv自带的dft()。DFT这个技术手段是将空间域映射到频率域中去,在图像处理有着举足轻重的地位。这里我们只是得到其变换的结果并看看贫域图有什么特点。 实验功能: 单击Open Image按钮,手动选择打开一副图片,不管其是否是彩色图片,这里统一将其转换成灰度图像显示,因为需要加快DFT运算速度。 将鼠标移动到图片显示区域,单击图片,这时会显示DFT中间结果图,也就是没有将低频域的点移动到图片的中心
OpenCV_PseudoColor
- 数字图像处理 伪彩色增强 将灰度值分别按照一定函数关系转换到RGB 空间中,形成彩色图像-Pseudo-color enhancement of digital image processing of the gray values were converted in accordance with certain functional relationship to the RGB color space to form a color image
EX1
- 1.用OpenCV实现打开一幅彩色图像,显示出来; 2.将其转换为灰度图并保存为文件; 3.将其二值化并保存为文件(二值化阈值最好用滚动条交互式输入,图像二 值化效果能实时变化更好,可参考OpenCV的sample程序edge.c)-1 using OpenCV open a color image display 2 converted to grayscale and saved as a file 3 the second value and save
edge
- 主要是采用Canny算法进行边缘检测,有一个个跟踪条,涉及到callback函数,对灰度图像进行边缘检测,将彩色图像转换为灰度图像-Using Canny algorithm for edge detection, a track bar relates to the callback function, for edge detection of gray image, the color image is converted to grayscale images
