The idea is to add a cookie manager within a thread group, log in, and extract it to sessionid with a regular, so that the session can be shared by the actions under that thread group.1. Create new thread group, Cookie Manager, HTTP request-Login, post-processing regular extractor under Login node, HTTP request-logoff, result tree2. When we log in, we can see the jsessionid information in the response headers of the sampling result, we need to take th

Suppose you want to open a file with Ofstream. and save the file data at the same time. You can only open the mode by displaying the specified app.For example, the following is the open func
Many people asked how to extract Word, Excel, PDF and other files, here I summarize the extraction of Word, PDF, several methods.
1, with Jacob.
In fact, Jacob is a bridage, connecting Java and COM or Win32 functions of a middleware, Jacob can not directly extract files such as word,excel, need to write their own DLL Oh, but has been written for you, is the author of Jacob together.

Link extractorsLink extractors are those objects that are simply extracted from a Web page ( scrapy.http.Response object) that will eventually be follow linked?Scrapy provides 2 available link Extractor by default, but you can create your own custom link Extractor by implementing a simple interface to meet your needs?Each linkextractor has the only public method that extract_links it receives an Response ob
get a good feature. But this requires a lot of heuristic rules and manpower to adjust the parameters according to the different fields to achieve a good accuracy, which is said to approach the human level. This is why using traditional computer vision technology takes years to create a good computer vision system (such as OCR, face verification, image recognition, object detection, etc.) that can handle a wide variety of data in real-world applications. Once, it took us 6 weeks to build a CNN m

(1) speed/accuracy trade-offs for modern convolutional object detectors
Its main consideration is three kinds of detectors (Faster RCNN,R-FCN,SSD) as the meta structure, three kinds of CNN Network (vgg,inception,resnet) as feature extractor, change other parameters such as image resolution, proposals quantity, etc. The tradeoff between accuracy rate and speed of target detection system is studied.
(2) Yolo9000:better, Faster, stronger
It is an upgrade
Basic methods:(1) Use CNN to process images.(2) Weighting the processed features as input to the RNN.Figure 1. The four original images at the bottom of the model structure diagram are the input of the CNN feature extractor, and after the same CNN, four feature F is obtained, then the weights are combined into UT, and the weighting is at. UT is a fixed-length eigenvector and is used as an input to the RNN.

3D game collision detection was mostly based on grids or BSP / span> tree, the lattice-based system is easy to implement but not accurate enough. It is not strictly 3D collision detection. Collision Detection Based on the BSP tree was once very popular, and the algorithm was basically mature and finalized. However, its inherent shortcomings make it unsuitable for current games. The BSP tree requires a long pre-processing time and is not suitable for computing during loading, BSP usua
