Computer vision is concerned with modeling and replicating human vision using computers and is divided into three basic categories as follows:

Low-level vision are the standard procedures to improve image quality and format. This includes standard image processing procedures. No intelligence is involved here. Mid-level vision includes extracting features (like edges and corners) and characterizing components (like regions). This involves some intelligence. High-level vision includes recognizing patterns and comparing to known models. This is image understanding and involves high intelligence (i.e., machine learning).

Provide at least 4 computer vision problems that can be solved using these categories.
