here. Ii. Introduction to OpenCV I think the internet on this aspect of the good tutorial for everyone to post it, I am afraid to speak bad words recruit jokes. The first is the series of blog of the light ink God, I basically learned from the blog of the Great God, and his "OpenCV3.0 Programming Primer" (strongly recommended. Very easy to understand. Online a search can be) Light Ink OpenCV Introductory

Python detailed process of crawling Coursera course resources, coursera Course Resources Sometimes we need to add some classic things to our favorites and review them from time to time. Some courses on Coursera are undoubtedly classic. Most of Coursera's finishing courses provide complete teaching resources, including ppt, video, and subtitles. It is very easy to learn offline. Obviously, we won't download
These days to implement OPENCV-related features on the Android platform, read a few blogs, papers, and finally achieved a simple example of OPENCV development on Android. In the period encountered a lot of large and small problems, now summed up. Of course, there are a lot of problems I do not very understand, I hope everyone is not hesitate to enlighten.first ,
bytes occupied by each row of images is stored by the member variable step. So: Data + = Image.step; Causes data to point to the first memory address of the next line of images. Of course, these operations are relatively low-level pointer operations, not recommended. using iterators to traverse image data Iterator is used extensively in the Standard Template Library (STL) of C + +. OpenCV also imitates S
approximate contour, which will distort the image's outline.Of course, there is a difference between a green line and a red line on the top of Sudoku. So at the moment of bending, I didn't get the primitive boundaries of Sudoku.My question:How do you distort the image on the correct boundary of Sudoku, the red line, or how to eliminate the difference between the red and green lines? Is there such a way in OpenCV
Recently, opencv is used for image processing. Many people on the internet use Vs and opencv, but they do not like vs very much and want to use QT creator. I searched a lot of materials online and finally spent a day using opencv on QT creator. Required Software: (1) Qt creator. My version is 4.8.5. This version is still installed when learning the QT creator of

Summary:Due to the recent AR (augmented reality) concept is very hot, a variety of AR-based applications and games are gradually facing the public, and in the AR is the most important two technology is tracking recognition and enhanced rendering, in which tracking recognition is through OPENCV this open-source computer vision Library to achieve, so I want to study this library, Here is a personal study note, not an authoritative tutorial, if you have
With VS use opencv time, do not want to configure the global, every time to configure is simply annoying.In view of this, we introduce a simple method.The prerequisite for configuring the environment is that the appropriate version of OPENCV is installed successfully.I am using OpenCV2.4.9, this version of the extract, find a directory called build, this is already compiled.Let's assume that the build direc

The imwrite_jpeg_quality type is long and must be converted to int; for PNG, the third parameter represents the compression level. Cv2.

Image Smoothing refers to the direct operation of each pixel data of the source image to achieve the purpose of smoothing the image. Essentially is the master convolution accounting sub-realization, convolution accounting sub-related knowledge you can refer to my blog http://blog.csdn.net/wenhao_ir/article/details/51691410Image smoothing, also known as blur or filtering, is one of the most commonly used techniques in image processing, and it is necessary to use the filter kernel (convolution acc
