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 training of XML file and the reali

This time to bring you the Python configuration and OpenCV use of the detailed, Python configuration and OpenCV use of the attention of what, the following is the actual case, together to see. After downloading opencv2.4.9 (python2.7 match) (1) running OpenCV 2.4.9.exe; (2)

Python learning-extract palm and some palm prints using opencv-python, The last time we successfully trained the palm reader http://www.cnblogs.com/take-fetter/p/8438747.html, we can get the recognition result. Next, we need to use opencv to obtain the palm of your hand and remove the background. here we need to use m

Opencv-python: Image size, image reading, display, saving and copyingoriginal November 23, 2017 21:30:49 4440 When you use the OpenCV method, you must first import the OPENCV package. The new OpenCV is imported into the CV2, and here is a comparison with the C

Recently learning Python, and if you have image processing, try to use the OpenCV library under Python, and here are some things to note about configuration installation:(If you've already installed OpenCV 2, and Python2.7) 1. What do you think of your OPENCV versio

The biggest difficulty with installing OPENCV under MACOSX is to coordinate the Python version. Because on the OPENCV website, it is highly recommended to install the full version of Python (not recommended with the Mac built-in Python), so you will encounter this multiple

The following features are implemented with Opencv+python:1) Get real-time video, decompose frame frequency;2) The video to do two value processing;3) The Video filter processing (to remove noise, to obtain the exact number of profiles);4) identify image contour;5) Calculate the centroid;6) depict the dynamic change curve of centroid;#-*-Coding:utf-8-*-"" "Created on Thu Apr 12:10:23 2018@author:irene" "" I

Recently began to learn OPENCV to perform computer vision experiments, chose Python as the experimental language, 工欲善其事, its prerequisite. Summarize the installation configuration first.Now OPENCV visual only supports the python2.7x version, but also relies on the numpy and matplotlib two class libraries.(I) Pre-preparation1.
