What is the difference between "image processing" and "remote sensing image processing and recognition"?

Remote sensing image processing and recognition is a research direction of image processing. The difference between them is that image processing mainly involves computer algorithms to store and analyze images (photoshop is a very typical image processing software), while remote sensing image processing is more inclined to extract useful information from remote sensing images by using the knowledge of different disciplines. For example, in order to obtain quantitative information of dust weather from remote sensing images, it is not enough to know only the knowledge of image processing, but also the atmospheric knowledge involved in this process, such as brightness temperature and aerosol optical thickness.

As far as I know, pattern recognition can be classified into the category of remote sensing image processing here. In the field of remote sensing, pattern recognition can be regarded as a method to extract remote sensing thematic information. The most familiar example is the use of supervised or unsupervised classification to obtain land use information. This information extraction process can be regarded as a workflow of remote sensing image processing, so pattern recognition belongs to remote sensing image processing.

It is difficult to generalize the employment problem. After all, everyone's situation is different and their choices are different. At the same time, there are different opinions on the Internet. But at present, some research institutes or similar information centers are better choices.

Good luck.
