Specifics of Thermal Images and Heatmap Annotation

Thermal imaging and heatmap annotation have existed for quite some time. But with the rise of Artificial Intelligence and Deep Learning, this technology has acquired new opportunities.

Nowadays, AI-assisted data annotation allows automatically detecting of objects on heatmaps. AI is incredibly powerful when it comes to reading and interpreting signals that cannot be otherwise accessed by humans. This includes electromagnetic radiation, infrasounds, and ultrasounds. This makes thermal image object detection significantly more precise and efficient.

In this guide, we’ll define the potential that thermal object detection, Machine Learning, and AI hold together. Heat vision cameras are used in a variety of fields from agriculture and healthcare to emergency evacuations and rescue missions.

Application Cases for Heatmap Annotation

Infrared images and object detection heatmap solutions can be used in a variety of cases. The main goal is to visualize signals/information that is not visible to the human eye. For example, reading thermal images allows identifying various objects in poor visibility conditions. A rescue mission dealing with a smoky fire scenario can use thermal drone annotation to locate survivors.

Other usage cases include:

  • Farming;
  • Construction;
  • Electrical sector;
  • Plumbing;
  • Animal and pest management;
  • Healthcare;
  • Science and Research;
  • IoT systems;
  • Fire-fighting;
  • Transport navigation;
  • Ecology and wildlife preservation;
  • Military purposes;
  • Law enforcement purposes.

Overall, thermal infrared imaging can detect humans, animals, buildings, rocks, engines, vehicles, liquids, leaks, gas, etc. And in comparison to RGB cameras, infrared ones give more privacy to people as they cannot be easily identified here. At the same time, infrared cameras and night annotations are perfect for ventilation and air conditioning systems or quality assurance in manufacturing.

Specifics of Thermal Image Annotation

One of the biggest challenges when it comes to thermal video semantic segmentation and heatmap annotation is the necessity to prepare a huge amount of data to train such an AI-based system. To perform to its best, a deep learning network needs to access millions of already annotated near infrared images.

There are no ready-to-use 3d thermal imaging datasets out there. So every project that works on a deep learning system needs to create its own dataset of such imagery. These images need to be annotated correctly to train the system to detect and recognize objects later.

The creation of such datasets requires a team of humans to manually annotate thermal anomalies and infrared images.

Types of Data Annotation for Thermal Object Detection

Specialists that work with heatmap annotation and nighttime image interpretation label different areas based on the temperature. They mark specific areas based on various types of data annotation derived from the shapes used. These are:

  • Lines and splines (using curves and lines);
  • Bounding boxes (2D or 3D boxes around objects);
  • Tracking for movement across many frames;
  • Polygonal segmentation (used for irregular shapes);
  • Landmark annotation (used not only for landscapes but for facial traits, gestures, or poses for facial recognition).

As for types of classification and segmentation used for annotations for night, there are:

  • Image classification;
  • Object detection;
  • Segmentation (semantic, instance, or panoptic).

Benefits of Outsourcing Annotations for Night Images

Outsourcing is a great opportunity when it comes to thermal image object detection and the preparation of huge datasets of annotated imagery. The main advantages of outsourcing night images data annotation are:

  1. Reduction of costs. Outsourcing is very cost-efficient as the salary rates in other countries are lower. Also, project-based cooperation and flexible schedule allow for saving a decent part of a budget.
  2. Productivity. Working with specialists means better quality of work, higher performance, and faster delivery. There is no need to train employees as they are already experienced in the annotation.
  3. You get more time to focus on the core of your business instead of taking resources to thermal image annotation.
  4. Faster project delivery. As everyone works on their respective area of responsibility, every specialist is able to perform better, faster, and easier. This ensures faster and smoother delivery;
  5. Usage of latest methods and technologies. Agencies and individuals that work with thermal image annotation offer access to the latest technology and innovations in the field.
