In OpenCV, image color space conversion is a common image processing task. OpenCV provides a series of functions for converting between different color spaces. Here are some common color spaces and their conversion methods: Image color null purpose Different color spaces have their own advantages and uses in the fields of image processing and computer […]

Space complexity and time complexity of sorting algorithm
1. Time complexity and space complexity of sorting algorithm Sort Algorithm Average time complexity Worst time complexity Best time complexity Space complexity Stability Bubble sort O(n2) O(n2) O(n) O(1) ? Direct selection sort O(n2) O(n2) O(n2) O(1) ? Direct insertion sort O(n2) O(n2) O(n) O(1) ? Quick sort O(nlogn) O(n2) O(nlogn) O(nlogn) ? Heap sort […]
OpenGL space coordinate transformation
First, you need to understand matrices. Matrices are often used for coordinate transformation in programs. Common matrices are: 1. Scaling matrix 2. Displacement matrix More one-dimensional coordinates: Homogeneous Coordinates use: 1. Allows us to displace on a 3D vector (we cannot displace the vector without the w component) 2. Divide the x, y and z […]
[Data structure] Time complexity and space complexity
Foreword The time complexity and space complexity of an algorithm are two core concepts used to evaluate the efficiency of an algorithm. Time complexity refers to the computational effort required to execute an algorithm, and it determines how fast a program runs. Space complexity refers to how much memory space is consumed to execute the […]
8. Managing Tablespaces and Data Files
Define the purpose of table spaces and data files Create tablespace Manage table spaces Use Oracle Management Files (OMF) to create and manage table spaces and obtain table space information Oracle logically stores data in table spaces and physically stores data in data files. 1. Table space 1.1 Table space and data files 1.1.1Tablespaces: -can […]
The namespace status in the k8s cluster always shows Terminating
1. Problem phenomenon When I was doing testing today, I couldn’t start the pod in a namespace. When I checked the ns status, it kept showing Terminating. [root@node1 ~]# kubectl get ns NAME STATUS AGE configmap Terminating 135d defaultActive 207d Harbor Active 207d kube-flannel Terminating 17m kube-node-lease Active 207d kube-public Active 207d kube-system Active 207d […]
The problem of Mysql table space and ibdata1 file being too large
Cause analysis ibdata1 is a file used to build the innodb system table space The above is a database ibdata1 file, which reaches more than 780 G and is still growing. This file contains the innodb data dictionary, modified buffer and double-write buffer, undo log, and also contains table information and index data created by […]

Analysis and ideas: Clear mines through the Windows mini-game By playing this mini-game, it is not difficult for us to discover this It is a chessboard composed of two-dimensional arrays and […]
Oracle tablespace
1. Concept 1.1 The relationship between users, tables and table spaces Each project corresponds to a table space. Oracle database stores physical tables through table spaces. A database instance can have N table spaces, and one table space can have N tables. Then create a user corresponding to this table space Therefore, when doing large-scale […]
