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.

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.

Sự hài lòng của bệnh nhân là yếu tố vô cùng quan trọng trong phẫu thuật nâng ngực. Một trong những yếu tố quyết định hàng đầu đến kết quả sau phẫu thuật là thể tích túi độn. [...] Với sự ra đời của mô phỏng ba chiều (3D), kỹ thuật này ngày càng được sử dụng nhiều hơn trong các buổi tư vấn trước phẫu thuật nhằm hỗ trợ bệnh nhân lựa chọn kích cỡ túi độn phù hợp nhất cho bản thân. Chúng tôi mong muốn nghiên cứu tính hữu ích của mô phỏng 3D như một công cụ hỗ trợ lâm sàng trong tư vấn tiền phẫu cho bệnh nhân nâng ngực.

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.

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.

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.
