idea of direct video frame background modeling, and the classical algorithm has the background subtraction method [32]. The algorithm uses principal component analysis (PCA) to decompose the continuous multi-frame video and then extract the foreground, and the proposed method also opens up a new development direction of moving target detection. There are many kinds of moving target detection algorithms, but none of them are suitable for moving target detection in all cases. Therefore, the key o

. the ElementTree module (ET) Provides Lightweight Python APIs. Compared with DOM, ET is much faster and many pleasant APIs are available, ET. iterparse also provides an "in the air" processing method, and there is no need to load the entire document to the memory. The average performance of ET is similar to that of SA

are consistent with the linux I/O model. When epoll notifies the read event, you can call the io system to call read to read data. When epoll notifies the write event, you can call the io system to call write to send data. When an error occurs, you can close and Recycle resources. Ctrl-related interfaces are used to set non-blocking options for socket. Why do we need to understand the epoll I/O model? In this article, we believe that in some cases, the complexity of the epoll operation co

Xml.etree.ElmentTree does not support CDATA output, but it supports comment output. Since you need to output XML text with CDATA blocks in your project, refer to the comment approach and modify the Elmenttree in theThe _serialize_xml method. The implementation is as follows:Import Xml.etree.ElementTree as ETdef CDATA (Text=none): element = ET. Element ('![ Cdata[') Element.text = text return elementEt._original_serialize_xml =

Profile tracking Objects with complex shapes cannot be expressed in simple ry. The contour-based method provides a more accurate shape description. The main idea of this method is to use the target model created in the previous frame to find the target region of the current frame. The target model can be a color histogram, a target edge, or a contour. Contour-based tracking methods can be divided into two types: Shape Matching Method and Contour Tracking Method. The former searches for the tar

to node 5. Node 5 is not responding, so node 4 declares itself elected and advertises the message to the other nodes. The Coordinator election process counts the number of nodes involved and ensures that at least half of the nodes in the cluster participate in the campaign. This ensures that in the case of network isolation only a subset of the nodes can select the coordinator (assuming that the network will be divided into a number of areas, the result is not connected to each other,

more nodes in the area of the selection of the coordinator, of course, if the region is more than half the number of nodes If the cluster is isolated into chunks, and no chunk has more nodes than half of the total number of nodes in the original node, then the coordinator cannot be elected and, of course, the cluster will not be expected to continue to serve.Resources M.
