Pattern recognition 1960s
The study of pattern recognition originated from the human need to classify and identify complex data. This field studies how to identify and classify patterns from data, involving feature extraction, feature selection, and classification algorithms. At that time, researchers hoped to solve the growing demand for data processing by building an automated lithuania mobile database pattern recognition system. However, early pattern recognition methods were usually based on manually designed features and simple classifiers, so their performance was limited by the quality of feature representation and the ability of the classifier. Despite this, the study of pattern recognition laid the foundation for the subsequent development of machine learning and artificial intelligence. In 1962, Thomas Bayes's "An Essay towards Solving a Problem in the Doctrine of Chances" described the Bayesian classifier in detail, becoming one of the important papers on pattern recognition.
Computer Vision 1970s
Early computer vision research focused on issues such as image processing, feature extraction, and scene analysis. The motivation for these studies was to simulate the human visual system so that computers could automatically recognize and understand image information. However, early computer vision methods were limited by computing power, image quality, and the limitations of hand-designed features. In the 1970s, David Marr proposed the theory of visual information processing, which divided visual processing into three stages: low-level, middle-level, and high-level. Marr's theory became an important milestone in the field of computer vision. In 1982, he published a book titled "Vision: A Computational Investigation into the Human Representation and Processing of Visual Information", which detailed the theory and implementation methods of visual information processing.
