[Opencv + python in ubuntu] install opencv in ubuntu This article will introduce how to install opencv 2.4.10 in ubuntu 14.04. I know that it is not easy to get started. It is better to teach people to fish than to teach them to fish. I hope I can help some friends. Prepare a stable system, select a source with good connection status (search for software update

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

OpenCV getting started, opencvOpenCV getting started-Key Point description child match Brute-forceThe keypoint descriptors matching is performed after the feature vectors are extracted from the image to determine the matching degree between the specific image and the image in the training set. The BFMatcher Brute force matching class inherits from the abstract class DescriptorMatcher, "Brute-force descripto

Install the source code to the specified directory: 2. Add an environment variable for opencv: Computer --> properties click Advanced Syste

The "OpenCV Getting Started Guide" series has been explained in eleven articles. I believe you have a preliminary understanding of OpenCV. Some netizens reported how they could not copy their own OpenCV programs to others' computers? For computer experts, this question is not worth mentioning. However, for new users, there is a detailed article to teach them to s

First of all, thank De Lihui Teacher Translation finishing of the "Opencv-python Chinese course", this document is really good, for OpenCV beginners, help is very large, can let beginners quick start. Recommend two OPENCV learning sites: (1) http://docs.opencv.org/2.4/index.html This site can query the use of OPENCV fu

Adjust the object recognition parameters of the AdaBoost Cascade classifier based on the Haar feature 1. Object recognition problem of AdaBoost Cascade classifier based on Haar featurePaul A. Viola and Michael J. Jones published in 2001 the article "Fast object detection using simple features to improve cascade detectors." At the same time, many bloggers in csdn from 07 to 13 have made a lot of work on the principle of this method, library function content, the

Recently, I am writing my own algorithms, which are actually an improvement for some traditional algorithms. For more information about traditional algorithms, see opecv source code. While reading the source code, I gradually realized the power of opencv, not because it implements various algorithms, but because it designs basic data structures, others can easily use these data structures to implement their own algorithms. The help manual provides det

[OpenCV] expands the image boundary and opencv expands the image boundary. In image processing, some attribute values at the current pixel position are often calculated using the adjacent pixels of the current pixel. This will lead to cross-border access to the border pixel. Generally, there are two ways to solve this problem: this article mainly introduces how to use O
