Scene Designer: a Unified Model for Scene Search and Synthesis from Sketch

no code implementations16 Aug 2021 Leo Sampaio Ferraz Ribeiro, Tu Bui, John Collomosse, Moacir Ponti

Scene Designer is a novel method for searching and generating images using free-hand sketches of scene compositions; i. e. drawings that describe both the appearance and relative positions of objects.

OSCAR-Net: Object-centric Scene Graph Attention for Image Attribution

no code implementations ICCV 2021 Eric Nguyen, Tu Bui, Vishy Swaminathan, John Collomosse

Our key contribution is OSCAR-Net (Object-centric Scene Graph Attention for Image Attribution Network); a robust image hashing model inspired by recent successes of Transformers in the visual domain.

Neural Architecture Search for Deep Image Prior

2 code implementations14 Jan 2020 Kary Ho, Andrew Gilbert, Hailin Jin, John Collomosse

We present a neural architecture search (NAS) technique to enhance the performance of unsupervised image de-noising, in-painting and super-resolution under the recently proposed Deep Image Prior (DIP).

An Internal Learning Approach to Video Inpainting

1 code implementation ICCV 2019 Haotian Zhang, Long Mai, Ning Xu, Zhaowen Wang, John Collomosse, Hailin Jin

We propose a novel video inpainting algorithm that simultaneously hallucinates missing appearance and motion (optical flow) information, building upon the recent 'Deep Image Prior' (DIP) that exploits convolutional network architectures to enforce plausible texture in static images.

Disentangling Structure and Aesthetics for Style-Aware Image Completion

no code implementations CVPR 2018 Andrew Gilbert, John Collomosse, Hailin Jin, Brian Price

Content-aware image completion or in-painting is a fundamental tool for the correction of defects or removal of objects in images.

Sketching With Style: Visual Search With Sketches and Aesthetic Context

no code implementations ICCV 2017 John Collomosse, Tu Bui, Michael J. Wilber, Chen Fang, Hailin Jin

We propose a novel measure of visual similarity for image retrieval that incorporates both structural and aesthetic (style) constraints.
