The journey of computer vision dates back to the 1960s when researchers began exploring ways to enable computers to interpret visual information. Over the years, significant milestones have been achieved, including the development of early image processing algorithms, pattern recognition techniques, and the emergence of artificial intelligence (AI) approaches.

Basics of Computer Vision

1. Image Acquisition

The process of computer vision starts with acquiring digital images or videos using cameras or sensors. These raw visual inputs serve as the foundation for subsequent analysis and processing.

2. Preprocessing

Before extracting meaningful information, raw images undergo preprocessing steps to enhance quality, remove noise, and standardize features. Common preprocessing techniques include filtering, noise reduction, and color normalization.

3. Feature Extraction

Feature extraction involves identifying relevant patterns or characteristics within the images. This step aims to highlight key elements that are crucial for subsequent tasks such as object detection, recognition, or classification.

4. Object Detection and Recognition

One of the primary objectives of computer vision is to detect and recognize objects within images or videos. This involves identifying specific entities, distinguishing between different classes, and accurately locating their positions.

Advanced Techniques in Computer Vision

1. Deep Learning and Neural Networks

Recent advancements in computer vision have been driven by deep learning techniques, particularly convolutional neural networks (CNNs). These deep-learning architectures excel in tasks such as image classification, object detection, and semantic segmentation.

2. Image Segmentation

Image segmentation divides an image into meaningful segments or regions based on shared characteristics. This technique is valuable for tasks like image understanding, scene analysis, and medical image processing.
