Continuous Memory Representation for Anomaly Detection

1 code implementation28 Feb 2024 Joo Chan Lee, Taejune Kim, Eunbyung Park, Simon S. Woo, Jong Hwan Ko

To tackle all of the above challenges, we propose CRAD, a novel anomaly detection method for representing normal features within a "continuous" memory, enabled by transforming spatial features into coordinates and mapping them to continuous grids.

Compact 3D Gaussian Representation for Radiance Field

1 code implementation22 Nov 2023 Joo Chan Lee, Daniel Rho, Xiangyu Sun, Jong Hwan Ko, Eunbyung Park

On the other hand, 3D Gaussian splatting (3DGS) has recently emerged as an alternative representation that leverages a 3D Gaussisan-based representation and adopts the rasterization pipeline to render the images rather than volumetric rendering, achieving very fast rendering speed and promising image quality.

FFNeRV: Flow-Guided Frame-Wise Neural Representations for Videos

1 code implementation23 Dec 2022 Joo Chan Lee, Daniel Rho, Jong Hwan Ko, Eunbyung Park

Neural fields, also known as coordinate-based or implicit neural representations, have shown a remarkable capability of representing, generating, and manipulating various forms of signals.

Masked Wavelet Representation for Compact Neural Radiance Fields

1 code implementation CVPR 2023 Daniel Rho, Byeonghyeon Lee, Seungtae Nam, Joo Chan Lee, Jong Hwan Ko, Eunbyung Park

There have been recent studies on how to reduce these computational inefficiencies by using additional data structures, such as grids or trees.
