5th CIE Expert Symposium on Colour and Visual Appearance

The 5th CIE Expert Symposium on Colour and Visual Appearance will take place in Hong Kong on 20-24 April 2020.

  • Abstract Submission is open and closes 23th October 2019.
  • Early Registration opens 11th October 2019.
  • For interested parties there are sponsorship opportunities available.

The symposium provided the attendees the opportunity to present the state of the art in our understanding of the perception of the visual attributes, such as colour, texture, translucency and gloss.

This CIE Expert Symposium aims to create a symbiosis between the different scientific disciplines conducting research about visual appearance and related attributes, comprising the fields of vision, metrology, and image technology.

Detailed information is available on CIE webpages .

Next Progress Meeting, 21-22 May 2019

The next progress meeting of BiRD will be held at CNAM, in La Plaine St Denis (FR), 21st May  (9 am – 5 pm) to 22nd May  (9 am – 12 am). Please, save the date in your agenda. If you plan to attend the meeting and have not registered yet, please contact us by email.

Following topics will be discussed :
– Progress on BRDF recommandations
– BRDF data file format proposal
– Measurement of Gloss
– Measurement of Sparkle
Details will be also given about BxDiff, our new project on BTDF & BSSRDF measurement and modelling, multiscale traceability, speckle and polarisation issues on BRDF. We will also have a breakout session to get your feedback, needs and remarks. And of course, coffee breaks and evening diner in Paris, to discuss in a non formal situation.

Date :
21st May (9 am – 5 pm),  22nd May  (9 am – 12 am)

Location :
CNAM
61 rue du Landy
La Plaine St Denis, France (see https://goo.gl/maps/r8YgdFQqmh52)

How to get to CNAM

Map Metro Paris

Agenda

Venue :
Take train RER B North (blue line) and stop at “La Plaine – Stade de France”. Caution, you have to buy a special Ticket (zone 1-2). Once there, it’s about 5 mn walk. Follow the map between the RER station and CNAM (see document attached).

Hotel :
Recommanded nearby Metro Stop “Gare du Nord” (8 mn), “Chatelet – Les Halles” (11 mn) or “Saint Michel Notre Dame” (13 mn).

Airport
Try to arrive at CDG Airport (north of Paris).
To go to Paris, 2 options :
“Paris by train” : 10€, 35mn. Buy a ticket at the airport. The connecting train CDG-Paris is the RER B, so it stops at “La Plaine Stade de France”  which is useful is you fly back in the afternoon.
Taxi : 55€, 25mn (according to traffic)

Train :
Thalys and Eurostar arrive in Gare du Nord. Then it’s 8 mn with RER B to get to “La Plaine – Stade de France

New stakeholder

We have an new industrial who joined the group of BiRD’s stakeholders.

For more information visit the Stakeholder Area.

pab-opto specializes in measuring BSDF and consults in projects with relate to material modelling and simulation. It is based on more than 20 years of experience building gonio-photometers for BSDF measurement and project work.
Their line of PG2 gonio-photometers is manufactured and marketed by the sister company pab advanced technologies Ltd.
