Image classification is the process of assigning a label to an entire image based on its visual content. This application is foundational in computer vision and serves as the basis for more complex tasks.

• Healthcare:

  Image classification is used in medical imaging to identify diseases and abnormalities in X-rays, MRIs, and CT scans. For instance, algorithms can classify images of skin lesions to detect melanoma.

  

• Agriculture:

  Farmers use image classification to monitor crop health and identify diseases in plants. Drones capture images of fields, and algorithms classify these images to determine the presence of pests or nutrient deficiencies.

  

• Retail:

  Retailers use image classification for product categorization and inventory management. Automated systems can classify products on shelves to ensure correct placement and availability.

  

Object detection involves not only classifying objects within an image but also locating them by drawing bounding boxes around each object. This application is more complex than image classification and is essential for many real-time applications.

• Autonomous Vehicles:

  Object detection is critical for self-driving cars to identify and locate other vehicles, pedestrians, traffic signs, and obstacles on the road. This capability ensures safe navigation and collision avoidance.

  

• Security and Surveillance:

  Surveillance systems use object detection to identify suspicious activities and unauthorized access. Security cameras can detect and alert authorities to the presence of intruders.

  

• Robotics:

  In manufacturing, robots use object detection to identify and manipulate parts on assembly lines. This enhances precision and efficiency in automated production processes.

  

Facial recognition is a technology that can identify or verify a person by analysing and comparing facial features from images or videos. It has become increasingly prevalent due to advancements in deep learning.

• Security:

  Facial recognition is used in security systems for access control and identity verification. Airports and border controls employ this technology to enhance security and streamline passenger processing.

  

• Social Media:

  Platforms like Facebook and Instagram use facial recognition to tag individuals in photos automatically. This enhances user experience by simplifying the tagging process and organizing images.

  

• Law Enforcement:

  Police departments use facial recognition to identify suspects and missing persons. This technology can match faces from surveillance footage with criminal databases to aid investigations.

  

Medical imaging leverages computer vision to assist in diagnosing and treating diseases. It involves analysing medical images to identify patterns and anomalies.

• Radiology:

  Computer vision algorithms help radiologists detect tumors, fractures, and other conditions in X-rays, MRIs, and CT scans. This improves diagnostic accuracy and speeds up the review process.

  

• Pathology:

  Automated systems analyse tissue samples to identify cancerous cells. This assists pathologists in diagnosing diseases and planning treatments.

  

AR and VR applications use computer vision to blend digital content with the real world or create immersive virtual environments.

• Gaming:

  AR and VR enhance gaming experiences by overlaying digital objects onto the real world or creating fully immersive virtual worlds. Computer vision tracks player movements and interactions.

  

• Education:

  AR applications provide interactive learning experiences by overlaying educational content onto textbooks and real-world objects. VR simulations offer immersive training for various professions.

  

Retail and e-commerce industries use computer vision to improve customer experience and streamline operations.

• Virtual Try-On:

  Online retailers offer virtual try-on solutions for clothing, accessories, and makeup. Customers can see how products look on them without physically trying them on.

  

• Inventory Management:

  Computer vision helps retailers track inventory levels and product placement. Automated systems can detect stockouts and misplaced items, ensuring optimal product availability.

  

Agriculture benefits from computer vision through precision farming and crop monitoring.

• Crop Monitoring:

  Drones equipped with computer vision technology capture aerial images of fields. Algorithms analyze these images to assess crop health, detect diseases, and monitor growth.

  

• Livestock Management:

  Computer vision monitors livestock for health and behaviour analysis. This helps farmers detect illnesses early and manage animal welfare.

  

Industrial automation uses computer vision for quality control, inspection, and process optimization.

• Quality Control:

  Computer vision systems inspect products for defects during manufacturing. This ensures high-quality standards and reduces waste.

  

• Predictive Maintenance:

  Vision-based systems monitor machinery for signs of wear and tear. Predictive maintenance reduces downtime by addressing issues before they lead to equipment failure.

  

Transportation and logistics industries use computer vision to enhance safety and efficiency.

• Traffic Management:

  Traffic cameras equipped with computer vision monitor road conditions and traffic flow. This data helps manage congestion and improve road safety.

  

• Package Sorting:

  Automated sorting systems use computer vision to read labels and direct packages to their destinations. This speeds up the logistics process and reduces errors.
