object detection using opencv source code

Discover object detection using opencv source code, include the articles, news, trends, analysis and practical advice about object detection using opencv source code on alibabacloud.com

(reproduced) using the SIFT and RANSAC algorithms (OPENCV framework) to achieve object detection and positioning, and to find the transformation matrix (Findfundamentalmat and findhomography comparison) pinned

transformation matrix. And the online about findhomography introduction is relatively few, so will let people misunderstand findfundamentalmat will calculate the transformation matrix.Try to return the matrix with the Findhomography function, in the template image, the object is already marked with a green box outline, according to the object's four boundary points, and the transformation matrix, you can get the transformed

Use the sift source code of David Lowe to implement left-behind object detection

David Lowe's sift has always been used by everyone. We can't compile it by ourselves. It's not as good as we can compile it. First, use sift to extract feature points from the target object as the basis for subsequent judgment. The purpose of the demo is to detect the target object in another video. We use opencv to read a video. Use sift to extract the feature p

Using opencv for camera interaction games and source code

Note: This example is from China's digital art online. It has not been debugged and is reprinted here. It is just for your reference. Source of the original is: http://www.cgblog.com.cn/e/DoPrint? Classid = 29 id = 9742. === Recently, I saw someone using flash and the camera to make an interactive game. I thought it was very interesting. I used the library function of

Prototype source code analysis-object Part 2: type detection

Nonsense: Originally, this prototype source code analysis was intended only for taking notes on Prototype Learning. However, sometimes a problem can be found to be more in-depth (although it is still an analysis), which breaks away from the original expectations, more and more questions. Today, I plan to write STR, but when I write it to the variable detection, I

Based on MATLAB calibration data, using OPENCV to realize the calibration of Binocular Stereo camera (source code)

of the principle is also, binocular calibration must be shot at the same time. This is a piece of code that you write and capture the image at the same time, press C, and you can save the image. #include By the way, in the Loop Cvreleaseimage (img_left), Cvreleaseimage (img_right), must be executed, or a memory leak will occur. If you don't believe it, open the resource manager and comment out that the program runs when you see that the memory is ri

Opencv extends latent SVM discriminatively trained Part Based Models for Object Detection

Opencv 2.4 implements the DPM program in C ++. The main difference between it and the previous C version is that it can detect multiple targets at the same time. During use, you can put the trained model in a folder, and put the image to be detected in another folder for detection. Unfortunately, the accelerated content is not considered. Latent SVM regression ¶ Discriminatively trained Part Based Models f

equalization to it, and do some preprocessing work. Next, we will detect the human face and call the detectmultiscale function. This function detects objects at different scales of the input image. The parameter image is the input grayscale image, and the objects is the rectangular frame vector group of the object to be detected, scalefactor is the scale parameter in each image scale. The default value is 1.1. The minneighbors parameter is the number
