Opencv experiences (1) The second chapter of learning opencv mainly introduces some common and interesting functions and data types, so that students at the beginning are more interested in image processing, although I do not understand the internal experiment of the function and the meaning of some defined constants, I am still very happy after learning Chapter 2. At least I know some basics of image processing, such as contour processing; Knowledge

Obtain a solid root of the high equation 2x ^ 4-4x ^ 3 + 6x ^ 2-8x-8 = 0 (accuracy requirement: 10 ^-3) Algorithm analysis is as follows: There are many real-root algorithms for High-Level equations. Here we introduce a kind of bipartite method. If the higher-order equation f (x) is set to 0, a real root algorithm is o

Init is one of the most indispensable programs in Linux system operation. Init process, which is a user-level process initiated by the kernel. The kernel will find it in several places in the past that used Init, and its correct location (for Linux systems) is/sbin/init. If the kernel cannot find Init, it will try to run/bin/sh, and if it fails, the boot of the system will fail.Linux 7 RunLevel (0: shutdown, shutdown mode,1: single-user mode,

Even if any thread is blocked in execution (sleep emulation is available), it does not affect other threads running.Suppose a long sleep is performed in thread 1.

There are four threads (1, 2, 3, and 4) to write data synchronously ......

as hardware raid, and features are not as good as hardware raid. Next we will introduce various RAID technologies I. RAID 0 The band technology is used to write data in parallel on multiple disks in bytes or bits (the starting offset of each disk is the same, and the subsequent segments of a certain number of bytes, i/O read/write performance can be improved, but it does not have data redundancy like raid1. Once the hard disk fails, it will be done.
