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.
ex01
- 在VC6.0和opencv下,简单的实现了彩色图像转换成灰度图-In VC6.0 and opencv, the simple implementation of the color image into grayscale
zhuanhuanhuidutu
- 将原始彩色图像转换成灰度图,利用opencv实现-opencv
edge-detection
- 将彩色图像转换为灰度图像并对其进行边缘检测 vs2008+opencv2.1运行成功-A color image is converted to grayscale and edge detection of its successful run vs2008+ opencv2.1
EqualizeHist
- 程序分别对彩色三通道图像和单通道的灰度图像进行了直方图均值化得处理。-Program were three channels of color images and grayscale images were single-channel histogram equalization have to deal with.
ReadPic
- vc6.0中使用opencv显示彩色图像和灰度图像。比已有的相关代码多了显示灰度图像的能力。-vc6.0 using opencv display color images and grayscale images. More relevant than the existing code has the ability to display grayscale images.
gray
- 图像灰度转化,将彩色图像转化为灰度图像,并且保存下来-Gray transformation
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
RGB_Gay(opencv)-
- opencv 彩色图像转化成灰度图并加以保存 可以成功运行 在vc6.0和opencv1.0运行成功 适合初学者-the opencv color images into grayscale and save can be run successfully in vc6.0, and opencv1.0 run successfully for beginners
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
lesson8
- 将一副彩色图像色彩均衡化,比直接灰度图像均衡化使用了通道分离,效果更好-A color image color equalization, channel separation than direct grayscale image equalization, the better
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
image_dilation
- 包括二值化图像的膨胀,灰度图的膨胀以及彩色图膨胀,代码简单易懂-Including the expansion of the binarized image, the grayscale expansion swelling, and a color chart code is simple to understand
1
- 基于opencv的图像灰度化,将24位彩色图像重新量化为8位灰度图像-gray image
cvCvtColor
- 一个可以对图像进行把彩色RGB图像转化成灰度图像并将原图和结果图像的程序。根据此模板可以进行处理显示结果的类似程序-An image can be converted to RGB color images to grayscale images and artwork and the resulting image program. This template can be processed according to display the results of a similar prog
GRAYTOPseudo-color-and-rainbow
- 将灰度图像转换成伪彩色图和彩虹图像,彩虹图像的效果比伪彩色好一些-The pseudo-color grayscale images into image maps and rainbow, rainbow image is better than some pseudo-color
calcHist
