The basic steps of digital image processing 1, image acquisition is the first step of digital image processing. Image acquisition is as simple as giving a digital image. Usually, the image acquisition stage includes image preprocessing, such as image scaling.

2. Image enhancement is the process of processing an image to make its result more suitable for a specific application than the original image. The word "concrete" is important because enhancement technology is based on problem orientation. For example, a method that is very useful for enhancing X-ray images may not be a good method for enhancing satellite images obtained in the infrared band of the electromagnetic spectrum. There is no general theory for image enhancement methods, and there are various image enhancement methods, which are handled under special circumstances.

3. Image restoration is also a processing field to improve image appearance. Unlike image enhancement, image enhancement is subjective, while image restoration is objective. Restoration techniques are often based on mathematical or probabilistic models of image degradation. Enhancement is a subjective preference based on what is a good enhancement effect.

4. Color image processing. The sixth chapter covers many basic concepts of color model and color processing in the digital field. Color is also the basis of extracting the region of interest in the image.

5. Wavelet is the basis of describing images with different resolutions. In this book, wavelet is used for image data compression and pyramid representation, when the image is successfully subdivided into smaller regions.

6. Compression refers to the process of reducing image storage or image bandwidth. The Internet is characterized by a large number of pictures. For example, jpeg image compression standard adopts jpg file extension. Jpeg format images can get better image quality with the least disk space.

7. Morphological processing includes tools to extract image components, which is very useful in representing and describing shapes. This chapter will begin with the transformation from output image processing to output image attribute processing.

8. Segmentation divides an image into its components or targets. Usually, automatic segmentation is one of the most difficult tasks in digital image processing. It is a difficult segmentation process to successfully segment targets one by one. Generally, the more accurate the segmentation, the more successful the recognition.

9. Representation and description. Selection representation is only a part of transforming the original data into a form suitable for computer subsequent processing. In order to describe the data and make the features of interest more obvious, a method must be determined. Description, also known as feature selection, involves extracting features, which can get some quantitative information of interest or be the basis for distinguishing a group of targets from other targets.

10. Target recognition is the process of giving the target a sign (such as "vehicle") according to its description.

How many kinds of image processing software (similar to N8) are there on the market now? Adobe series

1ADOBEPhotoshop simplified Chinese software category: image processing Photoshop is a famous image processing software, produced by Adobe company in the United States. It has a very powerful function when decorating photographic paintings. Adobe Illustrator is a powerful and perfect drawing software package, designed for output and web page making. This professional drawing assembly has become a powerful vector drawing tool, complete PostScript output, and closely integrated with Photoshop or other Adobe family software. Version 10 has added new drawing and automation advantages, such as arc, rectangular grid and polar grid tools. Increase the flexibility of editing and logo (editing a copy of the main object or image). You can use brushes and other creative tools on the toolbar, such as merging and data-driven coordinates, to help you build templates that link to the database. The new Illustrator also provides more network production functions, including image cropping and support for SVG enhancement. 3FireworksMX2004 Simplified Chinese Software Language: Simplified Chinese Software Category: Image Processing 4AutoCAD Design Related Software 1. CorelDraw 2。 CorelPainter is the ultimate choice of digital sketch painting tools, and it is an excellent imitation nature painting software with a comprehensive and realistic imitation nature brush. It is specially developed for digital artists, illustrators and photographers who are eager to pursue free creativity and need digital tools to simulate traditional painting. Being able to reproduce the effect of NaturalMedia by digital means, it is the best of its kind and has won unanimous praise from the industry. CorelPainter is widely used in animation design, architectural renderings, artistic illustrations and so on. The most important thing to realize is that it is best to add a tablet to the software. Although you can also draw with a mouse, it will be more difficult on the whole, and it is definitely not as smooth as handwriting. At present, the general versions are 6.0, 7.0, 8.0, IX and X, and the latest version is XI.
