Detecting China's PLA aircraft carriers

Aircraft carriers are the capital ships of navy fleets. In the last years, China has started the construction of additional carriers at a rapid pace, posing a serious challenge to the balance of military powers in the Indo-Pacific seas.

This document gathers information on optical satellite images of the 3 Chinese PLA aircraft carriers : Type 001, Type 002 and of the newly launched Type 003. It also includes a study of their homeports and related infrastructures, as well as a monitoring for their recent movements.

Detecting decommissioned fighter jets turned into UAVs

The PLA, China's military, owns more than 4,500 decommissioned J-6 fighter aircraft, most of which were active in the 1970s.

At the PLA's Dingxin Air Force Test and Training Base in the Gobi Desert, these old fighters are converted into unmanned aerial targets.

In this case study, find out what Preligens' AI software for strategic site surveillance has been spotting at the Longtian and Dingxin bases over the past month.

Georges Seurat, a scientific approach of the visible

In 1884, he completed his first major composition, Une baignade à Asnières, which was a great success in the contemporary art community. George Seurat had just developed the pictorial technique of "divisionism", also commonly known as pointillism.

This technique consists of juxtaposing small touches of colour on the canvas. Seen up close, the work seems to be composed of disordered dots of colour, but seen as a whole it gives life to more elaborate portraits or scenes. The dots take on their full meaning.

The computer vision technique known as segmentation is very similar in spirit to Seurat's divisionist art. Find out more in this podcast!

A word of vocabulary

Image segmentation is a computer vision technique that consists of automatically dividing an image into areas of pixels belonging to the same class of objects. It exists two types: semantic segmentation and instance segmentation. The former identifies all objects in an image belonging to the same category (the sheep set), while the latter identifies each unit belonging to the desired category individually (each sheep separately).

The mixture of these two types of segmentation is called panopticon.

What does simulation of racing yachts involve and what role does AI play?

Competitive sailing, and particularly the America's Cup, is comparable to Formula 1 in terms of research and development. As such, we make extensive use of simulators for both boat design, sailor training and performance optimisation. Very advanced models of the yacht are produced, both in terms of CFD (Computational Fluid Dynamics) and structure/deformation, hydraulic systems, etc.

Pioneering AI solutions for a safer world.

Preligens was created in 2016 by two engineers, Arnaud Guérin and Renaud Allioux, on the belief that intelligence professionals would never be able to cope with the tsunami of data made available by the huge investments made in sensors. They came up with the idea of using artificial intelligence (AI) to automate the analysis of this multi-sourced data and tip and cue analysts to unusual events requiring their expertise.

Based in Paris and present in 5 countries, Preligens employs 230 people, mostly scientists who form the largest AI team for Defence in Europe. The performance and accuracy of Preligens' solutions, which are internationally recognized and proven in the field, enable its users in the defence sector to be quickly enlightened about complex situations.
