Bit rate control is actually a coding optimization algorithm, which is used to control the video stream size. So what is the purpose of its control? We can imagine that the same video encoding format, the code flow is large, it contains more information, then the correspondi

A man wants to change his mind. The first thing to do is to read a good book, reading a book is like making a good friend, he can help you go your own way. The life of reading is
influence, can be called "X" or "Ghost", Newton called it "Force". Aristotle, formerly the Greek philosopher, thought that the movement of objects always required a catalyst to propel Galileo and Descartes and found that it was only when the state of motion changed that there was an external influence. In this way, he contrasts the ancient movement view with the modern movement view, and integrates philosophy and physics into one.This class I can hea
talk about what is intra-frame prediction and inter-frame prediction in the encoding process before understanding I-frame B-frame P-frames 1. Intra-frame predictive coding Intra-frame encoding is used to reduce spatial redundancy of images. In order to improve the efficiency of intra-frame coding, the spatial correlation of adjacent macro blocks
What is magnetic beads?Magnetic Beads have high resistivity and magnetic permeability, which is equivalent to a series of resistance and inductance, but the resistance value and Inductance Value Change with frequency. It has better high-frequency filtering characteristics than ordinary inductor, and presents resistance at high frequencies, so it can maintain a hi
The Java Code flaw Automatic analysis tool mainly has: Findbugs, PMD and Checkstyle tool. This article focuses on the use of FindBugs and briefly mentions the use of PMD and Checkstyle tools. 1 FindBugs is what. FindBugs is a Java bytecode static analysis tool that can help Java engineers improve code quality and eliminate hidden flaws. FindBugs check the class o
point of convergence, only to stop, so called the sliding correlation method. The received signal is multiplied with the local PN code, the correlation value is obtained, and then a threshold value is compared with the threshold detector to determine whether the useful signal has been captured. It utilizes the correl
motion, and uniform circular motion. The common characteristics defined by these physical quantities are: the variation of a physical quantity is equal within an equal period of time, and the ratio of the variation to the time used can represent the characteristic of the variation speed. Ii. Understanding of the "Ratio Method" 1. Understand the ins and outs
lighting systems, lenses, camera systems, and image processing systems. For each application, we need to consider the operating speed of the system and image processing speed, the use of color or black and white cameras, the size of the detection target or the detection of the target is not defective, the field of view needs, the resolution needs to be high, the contrast needs how big. From the functional point of view, the typical machine vision sys
