ColorVideoVDP-ML was awarded second place in the full reference category of ICME Generalizable HDR & SDR Video Quality. The new metric models both the low-level (ColorVideoVDP) and high-level (ML) human vision. Now the code is available at https://t.co/an4zvbXH1m

See "FaceExpressions-70k: A Dataset of Perceived Expression Differences" at SIGGRAPH'25.

Our study quantifies the perceived differences between facial expressions (including both inter and intra-expression differences on multiple actors).

Introducing our new SIGGRAPH'25 paper: "What is HDR? Perceptual Impact of Luminance and Contrast in Immersive Displays".

We investigated how the contrast and peak luminance of a display impact user preferences.

I will be giving Optica Webinar on ColorVideoVDP: A Visual Difference Predictor for Image, Video and Display Distortions https://t.co/4dOaRjp6Ry via @OpticalSociety

[Alex Chapiro @AlexChapiro]

We have a new paper coming out in NTIRE'25 (CVPR workshop) on "Training Neural Networks on RAW and HDR Images for Restoration Tasks".

See our manuscript to learn more: https://t.co/IMUnDxnzNz

Work done with colleagues at Meta and Cambridge University @hdrsci

[Alex Chapiro @AlexChapiro]

Come see my keynote, "Predicting Visible Differences in Virtual and Augmented Reality", at Electronic Imaging'25.

I'll be speaking on Feb 4th, in a joint session: Image Quality and System Performance (IQSP) & Human Vision and Electronic Imaging (HVEI).

Interested in joining my team at Meta?

I'm excited to hire two new scientists to join my team. We're looking for scientists that can help us invent 'breakthrough' AR glasses, going past the limits of industry-standard waveguides.

Our #SIGGRAPHAsia2024 honourable mention award for our work on AR-DAVID. https://t.co/PT0Evwie44

[Alex Chapiro @AlexChapiro]

Our work on AR-DAVID got the best paper award honorable mention at SIGGRAPH Asia 2024!

If you are in Tokyo, come see the talk at 5:16pm - 5:28pm in Hall B7 (1), B Block, Level 7!

[Alex Chapiro @AlexChapiro]

Announcing our @SIGGRAPHAsia work with @hdrsci lab studying the perception of distortions in augmented reality (AR) - Our data will help researchers create accurate metrics for AR.

Come see the talk on Dec 3rd, and check out the AR-DAVID project page: https://t.co/ClDBIsIL5E

Come see our work with @zhshjiang & co. on “FaceMap: Distortion-Driven Perceptual Facial Saliency Maps” at @SIGGRAPHAsia on Dec 6. We studied the perceived importance of face regions, creating saliency maps useful as priors for better face rendering.

@GuanLinsanity @10kenchen @nathanmatsuda @qisun0 Should be streamed by the @siggraph conference for those attending virtually!

[Alex Chapiro @AlexChapiro]

Tune in Monday @siggraph for @10kenchen’s award-winning paper talk. Our study brings interpretable results on how much power can be saved using perceptual rendering techniques for displays (LCD, OLED, w/wo eye tracking, and more). See our page for details: https://t.co/pwmzz4dq9h

[Alex Chapiro @AlexChapiro]

This Wed @siggraph, @hdrsci presents ColorVideoVDP: the 1st fully spatiotemporal color-aware metric. Our metric models display geometry & photometry, produces outputs in interpretable just-objectionable-difference units and runs fast. See our project page: https://t.co/mJjRQczrhG
