Spectro Expo 2018

A scientific conference

The 9th Workshop on Hyperspectral Image and Signal Processing : Evolution in Remote Sensing (WHISPERS 2018) has been colocated with Spectro Expo 2018.

Hands on sessions from our exhibitors

Hyperspectral field measurements made portable: Hands on session by Headwall

Attendants were proposed a real field hyperspectral measurement and go through the post-processing steps of a datacube acquired by the Nano Hyperspec® VNIR sensor by Headwall Photonics.

The main characters of this sensor are its portability and its flexibility of use in the field. The topics of lens focusing, sensor optimization, scan speed settings, radiometric and reflectance conversions has been covered and extensively explained to the auditors. The session started in the field where was acquired data, and moved to a room to look at the acquired data-cube.

perClass Mira: The easiest way to interpret
spectral images in minutes

Hands-on interpretation of spectral images using machine learning with perClass

In this lab session organized by perClass, was presented perClass Mira GUI for interpretation of spectral images. An example work-flow of performing supervised classification has been presented on different use-cases such as plant disease detection or remote sensing terrain classification. The lab session covered:


  • active learning tool for focusing the labeling process to relevant examples
  • interactive performance optimization based on multi-class ROC analysis
  • deployment of trained models in custom applications including real-time processing of a live data stream


Participants could installed perClass Mira on their own laptops and were encouraged to bring their own data.

Social Events


We had a great time on sunday evening enjoying some icebreaker in the exhibiting hall with a live performance from Prof. Paul Gader !

Meals and coffee breaks

Attendants were invited to a nice meal each noon in the exhibition hall, as well to two coffee breaks and one welcoming breakfast per day served by the Beurs Van Berlage special team

Attendees could also enjoy some typical bakery made in front of them called the “Poffertjes”. Delicious local pancakes to enjoy at the break !
