What are some examples of using image processing technology?

The application of digital image processing can be divided into two categories:

Basic processing: enhance the visual effect of the picture through various algorithms, such as contrast, noise reduction and so on. Typical applications include Photoshop and other software, or preprocessing various camera devices before outputting images.

Content processing: analysis of image content. Common applications include face detection and recognition (many digital cameras now have this function), video search, telephone conference assistance system, car assistance system (such as pedestrian detection, traffic sign recognition) and many other aspects, and such applications are currently in a rapid growth period.
