The incorrect description of the characteristics of digital images is

Incorrect description of digital image features means that original image information can be added.

1. A digital image is a digital representation of the original image. It can capture and represent the details and features of images through various digital coding techniques. Compared with traditional analog images, digital images have higher resolution and more accurate representation. Therefore, digital images can show the details and features of the original images more clearly, which is a great advantage of digital images.

2. Digital images are convenient for image processing. Through various digital image processing algorithms, digital images can be filtered, enhanced, segmented and recognized. These processing operations can improve the image quality, extract useful information and even realize some new functions. Therefore, the processing ability of digital images is incomparable to that of analog images.

3. Digital images facilitate the storage and transmission of image information. Digital images can be stored and transmitted by computer, and will not be disturbed and lost as easily as analog images. This makes the storage and transmission of digital images more reliable and efficient.

4. Digital images can improve the observation effect of images. Through digital processing, digital images can be converted into different colors, brightness and contrast to achieve better visual effects.

Application scenarios of digital images:

1. Aerospace: The application of digital image processing technology in aerospace technology includes not only the processing of photos of the moon and Mars, but also aircraft remote sensing and satellite remote sensing technology.

2. Biomedical engineering: Digital image processing is widely used in biomedical engineering, including CT technology, medical microscopic image processing and analysis, such as red blood cell and white blood cell classification, chromosome analysis, cancer cell identification and so on.

3. Industry and engineering: In the industrial and engineering fields, image processing technology has a wide range of applications, such as inspection and classification of parts on automatic assembly lines, defect inspection of printed circuit boards, stress analysis of elastic mechanics photos, resistance and lift analysis of fluid mechanics photos, and automatic sorting of mail.

4. Video and multimedia systems: Digital image processing technology is widely used in video and multimedia systems, such as image processing, transformation and synthesis in TV production systems, and collection, compression, processing, storage and transmission of still images and dynamic images in multimedia systems.

5. Scientific visualization: Image processing and graphics are closely combined to form a new research tool for scientific research in various fields.
