Diffusion Mental Averages

Phonphrm Thawatdamrongkit, Sukit Seripanitkarn, Supasorn Suwajanakorn

Can a diffusion model produce its own "mental average" of a concept-one that is as sharp and realistic as a typical sample? We introduce Diffusion Mental Averages (DMA), a model-ce…

Zero-shot Inexact CAD Model Alignment from a Single Image

Pattaramanee Arsomngern, Sasikarn Khwanmuang, Matthias Nießner +1

One practical approach to infer 3D scene structure from a single image is to retrieve a closely matching 3D model from a database and align it with the object in the image. Existin…

Where Is The Ball: 3D Ball Trajectory Estimation From 2D Monocular Tracking

Puntawat Ponglertnapakorn, Supasorn Suwajanakorn

We present a method for 3D ball trajectory estimation from a 2D tracking sequence. To overcome the ambiguity in 3D from 2D estimation, we design an LSTM-based pipeline that utilize…

Revisiting Diffusion Autoencoder Training for Image Reconstruction Quality

Pramook Khungurn, Sukit Seripanitkarn, Phonphrm Thawatdamrongkit +1

Diffusion autoencoders (DAEs) are typically formulated as a noise prediction model and trained with a linear- noise schedule that spends much of its sampling steps at high noise…

LUSD: Localized Update Score Distillation for Text-Guided Image Editing

Worameth Chinchuthakun, Tossaporn Saengja, Nontawat Tritrong +3

While diffusion models show promising results in image editing given a target prompt, achieving both prompt fidelity and background preservation remains difficult. Recent works hav…
