Image recognition refers to the ability of computers and software to interpret and make decisions based on visual inputs, typically from digital images or videos. This ability has been notably advanced by the development of artificial intelligence (AI) and machine learning (ML), particularly leveraging techniques from computer vision (CV) and deep learning (DL) algorithms like convolutional neural networks (CNNs).
How Image Recognition Works
Image recognition systems are typically trained using large datasets of labeled images. Through supervised learning, the system learns to identify patterns and features that distinguish various objects or scenes. For example, a model might learn to differentiate between a cat and a dog by being trained on thousands of images of both animals.
Key components in image recognition include:
- Feature Extraction: The process of identifying significant parts of an image, such as edges, textures, or shapes. These features are then used to classify the image.
- Classification Algorithms: Algorithms like CNNs analyze the features extracted to classify the image into predefined categories.
Các khái niệm liên quan
It's essential to understand related terms to fully grasp image recognition's capabilities:
- Object Detection: Unlike image recognition, which identifies the entire image, object detection delineates individual objects within an image. Techniques like Ultralytics YOLOv8 excel in this domain.
- Image Segmentation: This divides an image into segments, often highlighting the structures of interest, useful in medical imaging and autonomous driving.
- Instance Segmentation: It extends object detection by classifying and delineating each instance of an object within the image.

- Image Classification: Primarily focuses on identifying the class of the entire image (e.g., cat or dog). In contrast, image recognition can involve identifying instances or components within the image.
- Object Detection: Focuses on detecting and locating objects within an image, providing bounding boxes and labels. Image recognition can be a broader term encompassing this and more detailed analysis like segmentation.
