InstantAvatar: Efficient 3D Head Reconstruction via Surface Rendering

Recent advances in full-head reconstruction have been obtained by optimizing a neural field through differentiable surface or volume rendering to represent a single scene. While these techniques achieve an unprecedented accuracy, they take several minutes, or even hours, due to the expensive optimization process required. In this work, we introduce InstantAvatar, a method that recovers full-head avatars from few images (down to just one) in a few seconds on commodity hardware.

Case report on facial hidradenoma papilliferum, rare aggressive benign tumor

A rare case of hidradenoma papilliferum was diagnosed in a 70-year-old male patient presenting with a subcutaneous nodule on his nasolabial fold. Excisional biopsy was performed with sufficient safety margins to prevent residual growth, followed by reconstruction planning guided by Crisalix 3D images technology.

บทบาทของการจำลองภาพสามมิติในการผ่าตัดเสริมหน้าอก

ความพึงพอใจของผู้ป่วยมีความสำคัญอย่างยิ่งในการผ่าตัดเสริมหน้าอก โดยหนึ่งในปัจจัยที่มีผลต่อผลลัพธ์หลังการผ่าตัดมากที่สุดคือขนาดของซิลิโคนที่ใช้ [...] ด้วยการมาถึงของการจำลองภาพสามมิติ (3D) เทคนิคนี้จึงถูกนำมาใช้มากขึ้นในการให้คำปรึกษาก่อนผ่าตัด เพื่อช่วยให้ผู้ป่วยสามารถเลือกขนาดซิลิโคนที่เหมาะสมกับตนเองได้ เป้าหมายของเราคือการศึกษาความเป็นประโยชน์ของการจำลองภาพ 3D ในฐานะเครื่องมือทางคลินิกสำหรับการให้คำปรึกษาก่อนการผ่าตัดในผู้ป่วยเสริมหน้าอก Indian Journal of Medical Sciences, สิงหาคม 2023.

SIRA: Relightable Avatars from a Single Image

This paper introduces SIRA, a method that reconstructs human head avatars from a single image with high-fidelity geometry and factorized lights and surface materials. Experiments show that SIRA obtains state-of-the-art results in 3D head reconstruction while at the same time, it successfully disentangles the global illumination, and the diffuse and specular albedos.

Facial Anthropometry and Analysis in Egyptian Women

The purpose of this study was to establish facial soft tissue norms for the Egyptian female population between the ages of 18 and 50, as well as Several age-related changes in facial measurements. Facial measurements were obtained by both direct (caliper-based) and indirect (3D Crisalix software) anthropometric analysis.

H3D-Net: Few-Shot High-Fidelity 3D Head Reconstruction

Introduction to H3D-Net, a hybrid scheme that combines the strengths of model-based and model-free representations by incorporating prior knowledge into neural implicit models for category-specific multi-view reconstruction. This approach is applied to the problem of few-shot full head reconstruction.
