A Unified Multi-Phase CT Synthesis and Classification Framework for Kidney Cancer Diagnosis with Incomplete Data

no code implementations9 Dec 2023 Kwang-Hyun Uhm, Seung-Won Jung, Moon Hyung Choi, Sung-Hoo Hong, Sung-Jea Ko

In this paper, we propose a unified framework for kidney cancer diagnosis with incomplete multi-phase CT, which simultaneously recovers missing CT images and classifies cancer subtypes using the completed set of images.

W-Net: Two-stage U-Net with misaligned data for raw-to-RGB mapping

1 code implementation20 Nov 2019 Kwang-Hyun Uhm, Seung-Wook Kim, Seo-won Ji, Sung-Jin Cho, Jun-Pyo Hong, Sung-Jea Ko

Recent research on learning a mapping between raw Bayer images and RGB images has progressed with the development of deep convolutional neural networks.

Simple yet Effective Way for Improving the Performance of GAN

no code implementations19 Nov 2019 Yong-Goo Shin, Yoon-Jae Yeo, Sung-Jea Ko

In adversarial learning, discriminator often fails to guide the generator successfully since it distinguishes between real and generated images using silly or non-robust features.

Fast and Accurate 3D Hand Pose Estimation via Recurrent Neural Network for Capturing Hand Articulations

no code implementations18 Nov 2019 Cheol-hwan Yoo, Seo-won Ji, Yong-Goo Shin, Seung-Wook Kim, Sung-Jea Ko

In this paper, we propose a hierarchically-structured convolutional recurrent neural network (HCRNN) with six branches that estimate the 3D position of the palm and five fingers independently.

PEPSI++: Fast and Lightweight Network for Image Inpainting

no code implementations22 May 2019 Yong-Goo Shin, Min-Cheol Sagong, Yoon-Jae Yeo, Seung-Wook Kim, Sung-Jea Ko

To address this problem, we propose a novel network architecture called PEPSI: parallel extended-decoder path for semantic inpainting network, which aims at reducing the hardware costs and improving the inpainting performance.

Unsupervised Deep Contrast Enhancement with Power Constraint for OLED Displays

no code implementations15 May 2019 Yong-Goo Shin, Seung Park, Yoon-Jae Yeo, Min-Jae Yoo, Sung-Jea Ko

In the proposed method, the power consumption is constrained by simply reducing the brightness a certain ratio, whereas the perceived visual quality is preserved as much as possible by enhancing the contrast of the image using a convolutional neural network (CNN).

Parallel Feature Pyramid Network for Object Detection

3 code implementations ECCV 2018 Seung-Wook Kim, Hyong-Keun Kook, Jee-Young Sun, Mun-Cheon Kang, Sung-Jea Ko

To overcome this limitation, we propose a CNN-based object detection architecture, referred to as a parallel feature pyramid (FP) network (PFPNet), where the FP is constructed by widening the network width instead of increasing the network depth.
