Talking Papers Podcast: deep dives into research papers in computer vision, 3D, machine learning, and AI, with the authors who wrote them. Where research meets conversation. By researchers, for researchers.
Each episode is structured like the paper itself: a TL;DR / abstract to set the stage, then related work, approach, results, conclusions, and future work. We close with a bonus segment called "What did Reviewer 2 say?", where the authors share the candid peer-review story behind the publication.
Hosted by Itzik Ben-Shabat. Guests are PhD students, postdocs, and faculty from leading labs across academia and industry. Aimed at fellow researchers and graduate students who want the candid version of the work, not a polished press release.

3D Paintbrush - Dale Decatur
🎙️ Welcome to the latest episode of the Talking Papers Podcast! In this exciting installment, I had the pleasure of hosting Dale Decatur, a talented 3rd year PhD student from the University of Chicago's 3DL lab, where he studies computer graphics, 3D computer vision, and deep learning.
📄 In this episode, we delved into Dale's groundbreaking paper titled "3D Paintbrush: Local Stylization of 3D Shapes with Cascaded Score Distillation," which was recently published in CVPR 2024. The paper introduces a novel technique, 3D Paintbrush, that enables automatic texturing of local semantic regions on meshes through text descriptions. By creating texture maps that seamlessly integrate into standard graphics pipelines, Dale's method not only streamlines the texturing process but also enhances the quality of localization and stylization.
🌟 The innovative Cascaded Score Distillation (CSD) technique developed in this paper leverages multiple stages of a cascaded diffusion model to supervise local editing with generative priors learned from images at varying resolutions. This approach grants users control over both granularity and global understanding of the editing process, opening up new possibilities for simplifying the editing of 3D assets.
💡 My insights: This paper marks a significant advancement in democratizing 3D asset editing by leveraging text prompts, a trend gaining traction in the research community. The meticulous approach taken by Dale and his collaborators sets a new standard for local editing and paves the way for more accessible content creation in the 3D space.
🔍 Dale's journey to developing 3D Paintbrush is truly inspiring. Our paths first crossed at CVPR 2023 when he presented his 3D highlighter paper. Despite not featuring it on the podcast back then, our mutual acquaintance, Itai Land, reintroduced us at CVPR 2024, showcasing Dale's remarkable progress with 3D Paintbrush. It was evident that having Dale join us on the podcast was a must, and I'm thrilled to share his insights with our audience.

3DInAction - Yizhak Ben-Shabat
🎙️ **Unveiling 3DInAction with Yizhak Ben-Shabat | Talking Papers Podcast** 🎙️
📚 *Title:* 3DInAction: Understanding Human Actions in 3D Point Clouds
📅 *Published In:* CVPR 2024
👤 *Guest:* Yizhak (Itzik) Ben-Shabat
Welcome back to another exciting episode of the Talking Papers Podcast, where we bring you the latest breakthroughs in academic research directly from early career academics and PhD students! This week, we have the pleasure of hosting Itzik Ben-Shabat to discuss his groundbreaking paper *3DInAction: Understanding Human Actions in 3D Point Clouds*, published in CVPR 2024 as a highlight.
In this episode, we delve into a novel method for 3D point cloud action recognition. Itzik explains how this innovative pipeline addresses the major limitations of point cloud data, such as lack of structure, permutation invariance, and varying number of points. With patches moving in time (t-patches) and a hierarchical architecture, 3DInAction significantly enhances spatio-temporal representation learning, achieving superior performance on datasets like DFAUST and IKEA ASM.
**Main Contributions:**
1. Introduction of the 3DInAction pipeline for 3D point cloud action recognition.
2. Detailed explanation of t-patches as a key building block.
3. Presentation of a hierarchical architecture for improved spatio-temporal representations.
4. Demonstration of enhanced performance on existing benchmarks.
**Host Insights:** Given my involvement in the project, I can share that when I embarked on this journey, there were only a handful of studies tackling the intricate task of 3D action recognition from point cloud data. Today, this has burgeoned into an active and evolving field of research, showing just how pivotal and timely this work is.
**Anecdotes and Behind the Scenes:** The title "3DInAction" signifies the culmination of three years of passionate research coinciding with my fellowship's theme. This episode is unique as it's hosted by an AI avatar created by Synthesia—Itzik was looking for an exciting way to share this story using the latest technology. While there is no sponsorship, the use of AI avatars adds an innovative twist to our discussion.
