RECOGNITION AND LOCALIZATION
The main goal is to identify significant key points within an image for use in recognition, classification, or other analysis tasks.
This algorithm uses various techniques and methodologies to detect these distinctive points. The most common are based on corner detection, intensity gradients, blob filters, or machine learning methods like local feature descriptors.
Once key points are identified, the algorithm extracts additional information and features from the image around the identified points, creating a set of representative properties that can be used for subsequent recognition and analysis.
