Learning Naturally Aggregated Appearance for Efficient 3D Editing

1 code implementation11 Dec 2023 Ka Leong Cheng, Qiuyu Wang, Zifan Shi, Kecheng Zheng, Yinghao Xu, Hao Ouyang, Qifeng Chen, Yujun Shen

Neural radiance fields, which represent a 3D scene as a color field and a density field, have demonstrated great progress in novel view synthesis yet are unfavorable for editing due to the implicitness.

Optimizing Image Compression via Joint Learning with Denoising

1 code implementation22 Jul 2022 Ka Leong Cheng, Yueqi Xie, Qifeng Chen

The key is to transform the original noisy images to noise-free bits by eliminating the undesired noise during compression, where the bits are later decompressed as clean images.

IICNet: A Generic Framework for Reversible Image Conversion

1 code implementation ICCV 2021 Ka Leong Cheng, Yueqi Xie, Qifeng Chen

Reversible image conversion (RIC) aims to build a reversible transformation between specific visual content (e. g., short videos) and an embedding image, where the original content can be restored from the embedding when necessary.

Enhanced Invertible Encoding for Learned Image Compression

1 code implementation8 Aug 2021 Yueqi Xie, Ka Leong Cheng, Qifeng Chen

Although deep learning based image compression methods have achieved promising progress these days, the performance of these methods still cannot match the latest compression standard Versatile Video Coding (VVC).
