Corals and Fish Health Inspection Using ROV

Machine Vision Technology

What is Machine Vision ? 
A.K.A Computer Vision

Machine vision technology can overcome many challenges by using cameras, image recognition software, and advanced algorithms to automatically analyze visual data from the ocean.

Why Use Machine Vision ?

  • Fish and Corals Inspection
  • Identity different types of fish and corals, behaviour and health 
  • Identify potential health issues in fish and corals, such as infections, diseases, or other abnormalities, with much faster and more accurately.
Diving in the Reef

What are the Benefits ?

  • Increased detection accuracy
  • Detect better than human vision
  • Improved efficiency
  • Reduced costs

How Machine Vision Works ?

Computer Vision

  • Through camera

  • Feature extraction

  • Pre-processing

Advanced Algorithm

  • Object Detection

  • Segmentation Classification

  • Post-processi

Annotation of Datasets

Serranidae (Groupers)

Serranidae, commonly known as groupers, is a family of fish found in tropical and subtropical waters around the world.


Sharks, or Selachimorpha, are a group of fish known for their cartilaginous skeletons, streamlined bodies, and sharp teeth.


Corals are marine invertebrates that belong to the phylum Cnidaria. They are typically found in tropical and subtropical waters, where they form vast and diverse coral reef ecosystems

Scaridae (Parrotfishes)

Parrotfishes, also known as Scaridae, are a family of marine fish found in tropical and subtropical waters around the world.

Leaf Plate Coral (Montipora Florida)
