1, Introduction 1 past and present life of Haar classifier Face detection belongs to the category of computer vision. In the early stage, people's main research direction was face recognition, that is, to recognize the identity of people according to the face. Later, the demand for face detection in complex background is increasing, and face ...

1, Introduction 1 overview of genetic algorithm Genetic Algorithm (GA) is a part of evolutionary computation. It is a computational model that simulates the biological evolution process of Darwin's genetic selection and natural elimination. It is a method to search the optimal solution by simulating the natural evolution process. The algorithm ...

There are two commands for MATLAB to realize image decomposition and reconstruction: The first is one-layer wavelet decomposition dwt2 [CA,CH,CV,CD]=dwt2(X,'wname'); Where dwt2 represents discrete wavelet transform; X is the input parameter and is the image; ' wname 'is the name of wavelet; The output variable CA is the low-frequency decompo ...

1, Introduction According to the division of the International Radio Advisory Committee (CCIR, now ITU-R), short wave refers to the electromagnetic wave with a wavelength of l00ml0m and a frequency of 3MHz30MHz. Radio communication using short wave is called short wave communication, also known as high frequency (HF) communication. In fact, in ...

1, Introduction BP network (Back Propagation) was proposed by a team of scientists led by Rumelhart and McCelland in 1986. It is a multilayer feedforward network trained by error Back Propagation algorithm. It is one of the most widely used neural network models at present. BP network can learn and store a large number of input-output mode map ...

I. Introduction Mathematical morphology is a subject based on set theory. It is a powerful tool for geometric morphology analysis and description. The history of mathematical morphology can be traced back to the 19th century. In 1964, Matheron and Serra of France introduced mathematical morphology into the field of image processing based on the ...

1, Introduction 1 concept of particle swarm optimization algorithm Particle swarm optimization (PSO) is an evolutionary computing technology. From the study of predation behavior of birds. The basic idea of particle swarm optimization algorithm is to find the optimal solution through the cooperation and information sharing among individuals in ...

1, Brief introduction of handwritten capital letter recognition technology 0 Introduction In the teaching process of colleges and universities, examination is the most common teaching means of teaching evaluation and comprehensive practice. With the progress of science and technology, the way of examination marking has also undergone great cha ...

Ant colony brief introduction Ant colony optimization (ACO), also known as ant algorithm, is a probabilistic algorithm used to find the optimal path in the graph. It was proposed by Marco Dorigo in his doctoral thesis in 1992. Its inspiration comes from the behavior of ants in finding paths in the process of looking for food. Ant colony algor ...
