In this work we mainly focus on how we detect the object by using SSD algorithm, there are several other algorithms like CNN, R-CNN and etc. But SSD algorithm is simpler compared to other ones. Furthermore, we
MOG算法,即高斯混合模型分离算法,全称Gaussian Mixture-based Background/Foreground Segmentation Algorithm。2001年,由P.KadewTraKuPong和R.Bowden在论文“An improved adaptive background mixture model for real-time tracking with shadow detection”中提出。它使用一种通过K高斯分布的混合来对每个背景像素进行建模的方...
For example, a class label could be “dog” and the associated class probability could be 97%. On the other hand, an object detection algorithm not only tells you which objects are present in the image, it also outputs bounding boxes (x, y, width, height) to indicate the location of ...
在opencv中训练完模型后,可将SVM模型保存为xml文件,可以在实时性应用中通过C++接口调用参数文件,进行实时推断。 SVM继承自StatModel和Algorithm类。在opencv中使用SVM的一般流程如下: 创建模型 语法:cv2.ml.SVM_create()--->retval 作用:创建一个空模型。 配置参数 表格参考自:SVM参数设置总结(参考源码ml.hpp) - ...

For the purpose of this tutorial, we will design theapplicationto detect the logo of Toptal. The symbol has sharp corners, and that may lead one to think about how effective corner detection algorithms may be in detecting Toptal’s logo. After all, such an algorithm is both simple to use...
For example, given an input image of a cat, the output of an image classification algorithm is the label “Cat”. In object detection, we are not only interested in objects present in the input image. We are also interested in where they are located within the input image. In that ...
It's suggested to do comprehensive comparison and include the existing traditional algorithm (Aruco-based) for QR detection, as well as ZXing:https://github.com/zxing-cpp/zxing-cpp other group of students studied different versions of Aruco. Preliminary results are that the current default version...
