WELCOME AND OPENING KEYNOTE
9:00 – 10:00
A Brief Story of Superpixels, Radhakrishna Achanta,Swiss Data Science Center (Switzerland)
The number of pixels in images is steadily rising. While computing power and memory are getting cheaper, it is nevertheless difficult for algorithms to deal with memory and computational burdens posed by large images, image-stacks, and videos. To address the need to reduce the processing burden, superpixels were introduced and have since found their way into a large number of applications.
Superpixel segmetation algorithms need to be efficient in computation and memory consumption to be useful. In addition to touching upon the state-of-the-art, general approaches, and applications of superpixels, this talk presents three efficient superpixel segmentation algorithms. The first one is Simple Linear Iterative Clustering (SLIC), the second is a variant of this called Simple Non-iterative Clustering (SNIC), and the third is an algorithm that relaxes the requirement of having roughly equal size.

COLLEAGUE CONNECTION
Expanded Gamut Printing
during the Wed. morning coffee break Convened by Abhay Sharma, Ryerson University (Canada)
A new topic in traditional printing is to expand the color gamut using colorants such as orange, green, and violet, giving a CMYK + OGV process. This emerging technology is applicable to all printing processes—inkjet, digital, offset, flexog-raphy. Most inkjet proofers already use an expanded gamut ink set and there are many new digital presses with CMYK+ color capabilities. Pantone has a new swatch book, the EXTENDED GAMUT Guide - printed with 7 colors. Join this informal meeting to understand the challenges and opportunities of expanded gamut color printing.

20:15 – 21:00
Grab a drink at the bar and join colleagues for an interesting evening talk.
Color in Narrative, Andrea Chlebak, feature film colorist (Canada)
Color is an often subtle layer in the process of filmmaking. It adds dimension by enhancing or creating atmosphere, calling attention to certain details, or adding meaning by establishing a palette to a certain character. As a supervising colorist for feature, documen-tary, and commercial films, the speaker sheds light on the process of coming to a final look for a film; she’ll discuss her use of experimentation, intuition, and percep-tion as a toolset to determine how blue, dark, or saturated to make an image, and how she collaborates with directors and cinematographers to enhance the narrative through color.

THURSDAY KEYNOTE
9:00 – 10:00
Colour and Consumer Cameras: The Good, the Bad, the Ugly, Michael Brown, York University (Canada) Sponsored by HP Inc.
Cameras are now used for many purposes beyond taking photographs. Example applications include remote medical diagnosis, crop monitoring, 3d reconstruction, document recognition, and many more. For such applications, it is desirable to have a camera act as a sensor that directly measures scene light. The problem, however, is that most commodity cameras apply a number of cam-era-specific processing steps to the captured image in order to produce visually pleasing photos. As a result, different cameras produce noticeably different colors when imaging the exact same scene. This is problematic for applications relying on color because algorithms developed using images from one camera often will not work with images captured on another camera due to col-or differences. In this talk, I’ll discuss the current state of affairs for color on commodity cameras, common incorrect assumptions made in the scientific literature regarding image color, and recent developments that are helping to improve the situation

Closing Keynote and IS&T and CIC Awards
9:00 – 10:10
High Dynamic Range on the Big Screen, Anders Ballestad, CEO and co-founder, MTT Innovation Inc., a Barco Company (Canada)
High dynamic range (HDR) is slowly making its way to the big screen after firmly being established in the living room. For the cinema, there is consider-able excitement around high-contrast projectors as well as LED walls. MTT has developed an HDR projector based on a new image formation technique we name dynamic lensing. Source light is steered from dark regions to bright im-age areas, with dramatic results: deep black levels and a peak luminance ex-ceeding TVs and LED-walls using similar strength light sources as conventional projectors. The perceptual impact of drastically enhanced colour volume tech-nologies will be discussed, as well as a number of open questions around the creative workflow and the potential for new experiments in color science.
