What Is 2D Image Processing?

A two-dimensional image is a flat image that does not contain depth information. Two-dimensional means four directions: left and right, up and down, there is no front and back. The content on a piece of paper can be seen as two-dimensional. That is, there is only area and no volume.

2D image face recognition

Face recognition technology, as one of the most important biometric recognition technologies, can use each person's unique face features for identity recognition. In a modern society where information technology is highly developed, the identification and protection of personal information has become a top priority. Face recognition technology has quickly become an important technical means for identifying personal information due to its unique advantages such as high efficiency, accuracy, and non-contact. ^[1]

Two-dimensional image distance measurement

Aiming at the problems that the traditional direct contact measurement method cannot meet the automation and other problems in operation and use, in order to improve the accuracy and efficiency of the amount, an image-based non-contact distance measurement method is proposed. First, add a scale with a scale in the scene, and cross the scale between the measured objects; then use the camera to shoot the scene to obtain the real image of the scene, and perform related processing on the obtained image and mark it. Out of scale: Finally, the distance of the object is calculated by the formula, and compared with the distance measured by the vernier caliper. This solution omits a series of complicated steps such as camera calibration and image correction during the distance measurement process, thereby avoiding processing The error in the image effectively improves the accuracy and efficiency of digital measurement. The research results show that by comparing the experimental data with the data measured by the vernier caliper, the base ten non-contact measurement method is practical, effective, adaptable, and highly accurate, and the detection effect is improved compared with the traditional detection method. ^[2]
