Computer image processing technology

1. The definition of computer image processing

In a broad sense, computer image processing refers to all processes, technologies or systems that use computers to carry out image correlation, which has a profound intersection and infiltration with various fields. Such as industrial production, biomedicine, intelligent monitoring, virtual reality, life entertainment and so on.

Computer image processing includes: digital image processing, digital image analysis and understanding, digital image acquisition of actual things combined with sensing equipment, digital expression of image processing results, etc.

2. The specific content of computer image processing

(1) digital image processing

Computer is a kind of digital processing equipment, so the classic computer image processing mainly refers to digital image processing, including spatial processing, frequency processing, restoration processing, compression processing, morphological processing, segmentation processing and so on. What the computer needs to do is to run relevant programs and get the required image processing results. Commonly used programming languages are C, Matlab and so on.

In addition, IPP, OpenCV, MTL and other function libraries contain many classic and efficient image processing modules, which bring a lot of convenience to developers. The commercial software such as Photoshop makes the complex algorithm of computer image processing into a friendly user interface, which provides a simple and easy-to-use platform for photographers, advertising designers and other people who pay attention to applications. Visible computer image processing technology is widely used!

Generally speaking, digital image processing technology is mainly used for image preprocessing.

(2) Pattern recognition (PR) and computer vision (CV).

In addition to the basic improvement of the image itself, we can also use computer image processing technology to dig out deeper information in the image in order to achieve a wider application purpose. Such as identification, monitoring, analysis and prediction.

In real life, the word recognition, face recognition, intelligent monitoring, intelligent transportation, automatic and fast mail sorting, industrial non-contact online detection and so on are all based on computer image processing technology and related theoretical knowledge. In this field, people use the collected images and the powerful processing ability of computers to realize the intelligence and visualization ability of computers, making computers gradually become one of the key means to improve efficiency in life and production; At the same time, it can also accomplish many tasks that people could not accomplish in the past, and fundamentally change people's lifestyle and concepts.

(3) Virtual Reality and Multimedia

Virtual Reality (VR) is a hot research field at present, and its establishment and development can not be separated from the development of computer image processing technology to a great extent. Through this technology, it shows people different results in digital form. For example, 3D movies have brought people visual impact, 3D reconstruction technology of ct and PET has brought more reliable basis for doctors' diagnosis, and 3D scene simulation has provided researchers with richer research materials and expressions, and so on.

In addition, computer image processing technology is closely integrated with the development of multimedia technology and communication technology. The ubiquitous mobile TV, video call in full swing, and booming high-definition digital TV are all closely related to computer image processing technology, which deeply affects people's lives all the time.

3. The prospect of computer image processing

As the most active direction in the field of scientific research, computer image processing has attracted the attention of many scientific research units and enterprises at home and abroad with its unique charm and wide application. For example, the "TH-OCR" character recognition system developed by the Intelligent Graphic Information Processing Laboratory of Tsinghua University Department of Electronic Engineering and the "Digital Home" platform jointly developed by Microsoft and Intel are all classic cases of computer image processing applications. At the same time, there are countless products in the research and development stage, or mass production stage, waiting to set off the next round of "technology frenzy." Therefore, we have every reason to believe that computer image processing technology will eventually have a far-reaching impact on our life, work, study, entertainment and other aspects!
