significantly.
Then, the binary value of fuzzy image is evaluated. Any pixel that is not greater than 90 in the gradient image is set to 0 (black). Otherwise, the pixel is set to 255 (white).
# blur and threshold the image
blurred = Cv2.blur (gradient, (9, 9))
(_, Thresh) = Cv2.threshold (blurred, 90, 255, Cv2. Thresh_binary)
After performing this step, the resulting image is as follows:Step4: In the picture above we see a lot of black bees in the body area, we need to fill the space with whi
OPENCV provides two programs that can train their own cascading classifiers opencv_haartraining and Opencv_traincascade. Opencv_traincascade is a new program that is written in C + + using the OpenCV 2.x API. The main difference is that Opencv_traincascade supports both Haar and LBP (local Binary Patterns), and it is easy to add other features. Compared with the Haar feature, LBP features are integer features, so the training and detection process can
Openpose is a use of OpenCV and Caffe and written in C + + open Source Library, used to achieve multithreading of multiple key real-time detection, the author includes gines Hidalgo,zhe cao,tomas simon,shih-en Joo and Yaser Sheikh.

Although the library uses Caffe, the code can easily be ported to other frameworks, such as TensorFlow or torch. If you implement any of th
The no-flush mechanism of AJAX AJAX enables the detection of registered names to be displayed instantly in the registration system.
Common user registration is user input user name, the background program detects whether the user name in the database is duplicated and makes a sign of success and failure (when the user registers the duplicate will return to register), or a little humanization is to add a detection

Kinect provides a new approach to behavioral recognition and behavioral analysis by providing depth images. In this paper, a new feature is extracted from the Kinect skeleton data, and the difference between the fall detection and the similar fall detection behavior is achieved successfully. After the certification test, the effect is very good.
Implementation environment: K
Copy Code code as follows:
/**
* Param:o indicates the value of the detection
* Return: Returns the string "undefined", "Number", "Boolean", "string", "function", "regexp", "array", "Date", "Error", "Object" or "null" "
*/
function TypeOf (o) {
var _tostring = Object.prototype.toString; Gets the object's ToString () method reference
Enumerating the basic data types and built-in object types, you can further supplement the array's

1. The internal mechanism by which Linux performs write on the socket. It may involve some basic I/O mechanisms, and I can't figure out what's going on, running server and client separately, and then terminating the server so that client continues to write to the already established socket connection, and the first write successfully returns , the second execution process exits without any hint, and there's no return.
Answer: After the server process is aborted, the socket is closed and fin is s

The main point of the conflict (Conflict) is that when the client and server-side data are cud, an error occurs during the synchronization of the data being manipulat

The Susan algorithm is a method for dealing with gray-scale images, such as Smith from Oxford University in 1997, which is mainly used to calculate corner features in images. The Susan algorithm chooses a circular template (as shown in Figure 1). The pixel points that are waiting to be detected at the center of the Circular window template are called core points. The neighborhood of the core point is divided into two regions: areas where luminance values are similar to those of the core points (
