Like this way, it systems enable machines to understand images and videos.  It is transforming raw visual data into valuable insights.  This intricate process involves multiple stages and techniques. And these together create the foundation of visual understanding by machines.

Image Acquisition and Preprocessing:

At the outset, systems based on the technology require images or videos as input.  These visual data sources can be captured by cameras, sensors, drones, or any device capable of recording visual information.  However, these images are not always pristine.  They can be affected by factors such as lighting conditions, noise, and distortions.  This is where the preprocessing steps come into play.  Algorithms are employed to clean and enhance the images.  Techniques like noise reduction, contrast adjustment, and histogram equalization ensure that the input images are of a consistent and usable quality.

Feature Extraction:

Once the images are preprocessed, the next step involves extracting meaningful features.  Features are distinctive attributes of an image that provide Cues about its content.  For instance, edges, corners, textures, and colors can all be considered features.  These features play a critical role in distinguishing objects, patterns, and elements within an image.  Algorithms such as edge detection, corner detection, and texture analysis are employed to identify and highlight these features.

Pattern Recognition and Machine Learning:
