Computer Vision: Transforming the World with AI-Powered Insights

What is Computer Vision?

Computer vision is a field of artificial intelligence that enables machines to interpret and process visual data, such as images and videos, in a way similar to human vision. By leveraging deep learning algorithms, computer vision systems can analyze, identify, and make decisions based on visual information.

How Does Computer Vision Work?

Computer vision works by combining deep learning, image processing, and pattern recognition techniques. The process typically involves:

• Image Acquisition: Capturing visual data through cameras or sensors.
• Preprocessing: Enhancing image quality by reducing noise and normalizing data.
• Feature Extraction: Identifying key patterns or objects in the data.
• Classification or Detection: Using neural networks to categorize objects or detect their presence.

Applications of Computer Vision

Computer vision is transforming industries by automating tasks and enhancing efficiency. Key applications include:

1. Healthcare

• Medical Imaging: Detecting diseases from X-rays, MRIs, and CT scans.
