1, Introduction 1 PCA PCA (Principal Component Analysis) is a commonly used data analysis method. PCA is a method that transforms the original data into a group of data representation with linear independence of each dimension through linear transformation. It can be used to extract the main feature components of data and is often used for dim ...

1, Introduction This topic is a leaf recognition system based on MATLAB HU moment invariants. By calculating the geometric characteristics of various leaves, we can judge what type of leaves they belong to. Geometric moment was proposed by Hu(Visual pattern recognition by moment invariants) in 1962. It has translation, rotation and scale invar ...

1, Introduction Particle swarm optimization (PSO) is a numerical optimization algorithm based on swarm intelligence. It was proposed by social psychologist James Kennedy and electrical engineer Russell Eberhart in 1995. Since the birth of PSO, it has been improved in many aspects. This part will introduce the basic principle and process of par ...

1 Introduction As one of the 21 most influential technologies in the 21st century and one of the top ten technologies that change the world, Wireless Sensor Networks (WSN) is widely used in industry, transportation, medical treatment, environmental protection, military management and so on. WSN is usually composed of a large number of wireless ...

1, Introduction 1 subject background This topic is a population statistics system based on matlab. In recent years, many industries have great demand for people flow information, such as bus stops, subway stations, shopping malls, entrances and exits, etc. Through the population statistics system, the flow of people in various places can be co ...

1, Introduction 1 DCT algorithm: The full name of DCT transform is discrete cosine transform. Discrete cosine transform is equivalent to a discrete Fourier transform whose length is about twice its length. This discrete Fourier transform is performed on a real even function. Through the study of digital signal processing, we know that the spec ...
