[explanation]: 1. Portrait; Describe it. 2. Painted characters; portrait

draw

Also called "image".

(1) Draw, shoot, print or reflect images: The images on the TV are very clear.

② Images of objects: The basic function of eyes is to feel the stimulation of light and recognize images.

Picture:

Images are similar and vivid descriptions or portraits of objective things, and are the most commonly used information carriers in human social activities. Or an image is a representation of an objective object, which contains information about the described object. It is the most important source of information for people. According to statistics, about 75% of the information a person gets comes from vision.

Broadly speaking, images are all pictures with visual effects, including images on paper media, negatives or photos, televisions, projectors or computer screens. According to the different recording methods of images, images can be divided into two categories: analog images and digital images. Analog images can record image brightness information through the changes of some physical quantities (such as light and electricity), such as analog TV images; A digital image uses data stored in a computer to record the brightness information of each point on the image.

Junyou Association, an international image art promotion organization, expounds the image processing process: image processing is a technology that analyzes, processes and processes images to meet visual and psychological requirements. Image processing is the application of signal processing in image field. Most images are stored in digital form, so image processing refers to digital image processing in many cases. In addition, the analog image processing method based on optical theory still occupies an important position. Image processing is a subclass of signal processing, and it is also closely related to computer science, artificial intelligence and other fields. Many traditional methods and concepts of one-dimensional signal processing can still be directly applied to image processing, such as noise reduction and quantization. However, the image belongs to two-dimensional signal, which has its special side and different processing methods and angles compared with one-dimensional signal. Decades ago, most image processing was carried out by optical equipment in analog mode. Because of their parallel characteristics, these optical methods still occupy a core position in many application fields, such as holography. However, due to the rapid improvement of computer speed, these technologies are rapidly being replaced by digital image processing methods. Generally speaking, digital image processing technology is more universal, reliable and accurate. They are also easier to implement than analog methods. Special hardware is used for digital image processing. For example, the computer architecture based on pipeline has achieved great commercial success in this respect. Nowadays, hardware solutions are widely used in video processing systems, but commercial image processing tasks are basically realized in the form of software, running on general personal computers.

Picture:

1. painted, photographed or printed images.

2. Portrait; Describe it. Han's "On Preface": "If it is invisible, it cannot be like." "The History of the Later Han Dynasty, Biography of Women and Uncle Xian Xiong": "What does it look like to set up a heroic monument?"

3. Painted characters; Portrait of the Three Kingdoms Wei Zhi Zang Hongchuan: "Therefore, with images, it will be famous for future generations." Cai Yuanpei's Origin of Art: "The transition from static art to dynamic art is a dance, which can be regarded as a moving image."

Correction: Because the word "image" is used too much and wrongly, "image" refers to a mathematical concept, which is a picture+quadrant, so it is abbreviated as "image".
