[Introduction]
In an article, the founders of AFU repeatedly stressed the importance of positioning, a classic theory of Iris and Jack troot. For many online shoppers, when talking about essential oils, they will think of AFE. "AFE is essential oils !" This short advertisement has put "AFU" on the throne synonymous with "Essential Oil. The key to AFU's success lies in the deep understanding and grasp of the positioning theory.

In my opinion, I think image processing is still a good job. First, we can regard the image as a two-dimensional, three-dimensional or higher-dimensional signal. In this sense, image processing is the best job situation in the whole signal processing, because you must not only master (one-dimensional) basic knowledge of signal processing, as well as knowledge of Image Processing (two-dimensional or high-dimensional signal processing. Secondly, image processing is the foundation of computer visio
