Phong Nguyen

I am a PhD student at Center For Machine Vision and Signal Analysis (CMVS), University of Oulu, Finland, where I am co-advised by Prof. Janne Heikkilä and Prof. Esa Rahtu.

I have a MS in Electronics and Electrical Engineering (Autonomous AI Drone) at Dongguk University, South Korea where I was a research assistant for Prof.Kang Ryoung Park. I have a BS in Mechanical Engineering from HUST, Vietnam.

From May to November of 2021, I joined the Reality Labs Research, Sausalito where I was a research intern for Nikolaos Sarafianos, Christoph Lassner and Tony Tung. I am also very lucky to have a 2022 summer internship at NVIDIA Toronto AI Lab and work with Sanja Fidler and Sameh Khamis.

I'm interested in the topic of 3D reconstruction, novel view synthesis and neural rendering. My research combines 3D computer vision and deep learning.

We propose an architecture to learn dense features in novel views obtained by sphere-based neural rendering, and create complete renders using a global context inpainting model. Additionally, an enhancer network leverages the overall fidelity, even in occluded areas from the original view, producing crisp renders with fine details. Our method produces high quality novel images and generalizes on unseen human actors during inferences.

We propose a new cascaded architecture for novel view synthesis, called RGBD-Net, which consists of two core components: a hierarchical depth regression network and a depth-aware generator network. The former one predicts depth maps of the target views by using adaptive depth scaling, while the latter one leverages the predicted depths and renders spatially and temporally consistent target images.

This paper presents a novel neural architecture search method, called LiDNAS, for generating lightweight monocular depth estimation models. Unlike previous neural architecture search (NAS) approaches, where finding optimized networks are computationally highly demanding, the introduced novel Assisted Tabu Search leads to efficient architecture exploration.

This work proposes an accurate and lightweight framework for monocular depth estimation based on a self-attention mechanism stemming from salient point detection. Specifically, we utilize a sparse set of keypoints to train a FuSaNet model that consists of two major components: Fusion-Net and Saliency-Net.

In this paper, we propose enhancing monocular depth estimation by adding 3D points as depth guidance. Unlike existing depth completion methods, our approach performs well on extremely sparse and unevenly distributed point clouds, which makes it agnostic to the source of the 3D points.

We introduces Transformer-based Generative Query Network (T-GQN) which uses multi-view attention learning between context images to obtain multiple implicit scene representations. A sequential rendering decoder is presented to predict multiple target images, based on the learned representations. T-GQN not only gives consistent predictions but also doesn’t require any retraining for finetuning.

In this paper, we propose guiding depth estimation to favor planar structures that are ubiquitous especially in indoor environments. This is achieved by incorporating a non-local coplanarity constraint to the network with a novel attention mechanism called depth-attention volume (DAV).

We introduces the Generative Adversarial Query Network (GAQN), a general learning framework for novel view synthesis that combines Generative Query Network (GQN) and Generative Adversarial Networks (GANs).

We proposed lightDenseYOLO, a novel marker detector for autonomous drone landing using deep neural networks.

In this research, we determined how to safely land a drone in the absence of GPS signals using our remote maker-based tracking algorithm based on the visible light camera sensor.

During my free time, I made explaining videos for exciting computer vision papers at the Cracking Papers 4 VN Youtube channel. Here are some examples:
