Before diving into the details, let’s start this computer vision guide by understanding: What is computer vision?
What is Computer Vision?
Computer vision is a field of artificial intelligence that allows machines to interpret and understand visual information from the world, such as images and videos, to make decisions and take actions. Computer vision services can help businesses use this technology for a wide range of applications, from improving customer service to streamlining operations.
To make it clearer, here are some examples of computer vision in action:
- Face ID: Your smartphone uses computer vision to recognize your face and unlock the device.
- Scanning receipts: Apps like Expensify use computer vision to scan and extract data from receipts, making expense tracking automatic.
- Object tagging: Platforms like Instagram and Facebook use computer vision to automatically tag people in photos based on facial recognition.
Core components of Computer Vision
These technologies are fundamental to computer vision services, that empower machines to process and understand visual data. They include:
- Image classification: The process of categorizing an image into a specific label or class. For example, classifying images of animals into categories like "dog," "cat," etc.
- Object detection: Identifying and locating objects within an image or video. This is what powers autonomous vehicles to detect pedestrians, other vehicles, and obstacles.
- OCR (Optical Character Recognition): This technology is used to extract text from images or documents. For instance, scanning a printed document or handwritten note to make it editable.
- Facial recognition: This identifies individual faces in images or videos, used in everything from security systems to personalized user experiences.
- Image segmentation: Dividing an image into multiple segments to make it easier to analyze. For example, this could be used to identify different parts of a landscape or an object in detail.
How Computer Vision works?
In simple terms, computer vision follows a high-level flow to process and analyze visual data. Here’s the general process:
- Input: The process begins with visual data, usually an image or video captured by a camera or sensor.
- Preprocessing: The input data is then cleaned and prepared for analysis. This may include tasks like resizing, adjusting brightness, or converting colors to make the data easier for the AI model to understand.
- Detection/Recognition: The AI model uses neural networks and algorithms to identify objects, features, or patterns in the image. This is where feature extraction comes into play, where the system looks for key patterns (like edges, shapes, or textures) to understand what it’s "seeing."
- Output: Finally, the system makes a decision or classification based on the analysis, whether that’s identifying an object, extracting text, or making predictions.
High-level flow example:
Camera/Image → AI Model → Decision or Classification
For instance, a camera captures an image of a person. The AI model analyzes the image, recognizing patterns and features, and then it classifies the person (e.g., identifying a face or matching it to a database).
Key AI concepts in Computer Vision:
Neural Networks: These are algorithms inspired by the human brain, designed to recognize patterns in data.
Feature Extraction: This is the process of identifying key components in an image, like edges, shapes, or colors, which help the system understand what it’s looking at.
Pattern Matching: The AI uses pattern matching to compare features in the image against known patterns, helping it make decisions or classifications.
