Their winning submission introduces a mixture-of-experts framework for screen content super-resolution, combining the Implicit Transformer Super-Resolution Network (ITSRN) with a diffusion-based text refinement stage enhanced by LLM-assisted OCR correction. The team presented this work at IEEE ICME in Nantes, France. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What approach did the winning submission use for screen content super-resolution at ICME 2025 Track 3? The winning submission combined a mixture-of-experts framework pairing the Implicit Transformer Super-Resolution Network (ITSRN) for restoring general image structures with a diffusion-based text refinement stage inspired by TextSSR. The text refinement stage was further enhanced with Large Language Model-assisted OCR correction, targeting high-quality upscaling in bandwidth-constrained screen-sharing scenarios. _Teams working on video super-resolution for conferencing track research like this on daily.dev._ ## Similar posts on daily.dev - [Enabling responsive AI at SIDO 2026](https://daily.dev/posts/enabling-responsive-ai-at-sido-2026-qbxllf9ub) · Collabora Blog · 0 upvotes · 0 comments - [Machine Learning Blog \| ML@CMU \| Carnegie Mellon University](https://daily.dev/posts/machine-learning-blog-ml-cmu-carnegie-mellon-university-ynzk2dhmg) · ML CMU · 2 upvotes · 0 comments - [From AI video analytics to XR streaming at IBC 2026](https://daily.dev/posts/from-ai-video-analytics-to-xr-streaming-at-ibc-2026-k5jtnhrlg) · Collabora Blog · 0 upvotes · 0 comments - [Announcing Blue Sky Track Winners at ICDM 2025](https://daily.dev/posts/announcing-blue-sky-track-winners-at-icdm-2025-ejqwbns3e) · Computing Community Consortium · 0 upvotes · 0 comments - [Powered by Clearpath: Research Highlights from ICRA 2026](https://daily.dev/posts/powered-by-clearpath-research-highlights-from-icra-2026-xuxreruva) · Clearpath Robotics · 0 upvotes · 0 comments --- Tags: [#machine-learning](https://daily.dev/tags/machine-learning), [#open-source](https://daily.dev/tags/open-source), [#llm](https://daily.dev/tags/llm) [View this post on daily.dev](https://daily.dev/posts/collabora-takes-first-place-at-icme-2025-grand-challenge-fjdecjom0) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Collabora takes first place at ICME 2025 Grand Challenge","url":"https://daily.dev/posts/collabora-takes-first-place-at-icme-2025-grand-challenge-fjdecjom0","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/collabora-takes-first-place-at-icme-2025-grand-challenge-fjdecjom0"},"datePublished":"2026-08-11T08:54:22.035Z","dateModified":"2026-08-11T09:26:57.560Z","description":"Collabora's machine learning team, led by Marcus Edel, Vineet Suryan, and Aaron Boxer, won first place in Track 3 of the ICME 2025 Grand Challenge on Video...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/9c980fe02b001bac033ce84615b7422e?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/9c980fe02b001bac033ce84615b7422e?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"Collabora Blog","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Collabora Blog","logo":"https://media.daily.dev/image/upload/s--ZGZ0FjqS--/f_auto,q_auto/v1786438306/logos/collabora?_a=BAMAMicg0","url":"https://daily.dev/sources/collabora"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/collabora-takes-first-place-at-icme-2025-grand-challenge-fjdecjom0","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"machine-learning,open-source,llm","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Collabora Blog","item":"https://daily.dev/sources/collabora"},{"@type":"ListItem","position":3,"name":"Collabora takes first place at ICME 2025 Grand Challenge"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/collabora-takes-first-place-at-icme-2025-grand-challenge-fjdecjom0#faq","mainEntity":[{"@type":"Question","name":"What approach did the winning submission use for screen content super-resolution at ICME 2025 Track 3?","acceptedAnswer":{"@type":"Answer","text":"The winning submission combined a mixture-of-experts framework pairing the Implicit Transformer Super-Resolution Network (ITSRN) for restoring general image structures with a diffusion-based text refinement stage inspired by TextSSR.
