Push the Boundary of SAM: A Pseudo-label Correction Framework for Medical Segmentation

no code implementations2 Aug 2023 Ziyi Huang, Hongshan Liu, Haofeng Zhang, Xueshen Li, Haozhe Liu, Fuyong Xing, Andrew Laine, Elsa Angelini, Christine Hendon, Yu Gan

One key advantage of our model is its ability to train deep networks using SAM-generated pseudo labels without relying on a set of expert-level annotations while attaining good segmentation performance.

Detecting and measuring human gastric peristalsis using magnetically controlled capsule endoscope

no code implementations24 Jan 2023 Xueshen Li, Yu Gan, David Duan, Xiao Yang

In this paper, we develop algorithms to detect and measure human gastric peristalsis (contraction wave) using video sequences acquired by MCCE.

Cardiac Adipose Tissue Segmentation via Image-Level Annotations

no code implementations9 Jun 2022 Ziyi Huang, Yu Gan, Theresa Lye, Yanchen Liu, Haofeng Zhang, Andrew Laine, Elsa Angelini, Christine Hendon

To lessen the need for pixel-wise labeling, we develop a two-stage deep learning framework for cardiac adipose tissue segmentation using image-level annotations on OCT images of human cardiac substrates.

Multi-scale Sparse Representation-Based Shadow Inpainting for Retinal OCT Images

no code implementations23 Feb 2022 Yaoqi Tang, Yufan Li, Hongshan Liu, Jiaxuan Li, Peiyao Jin, Yu Gan, Yuye Ling, Yikai Su

To address these challenges, we propose a novel multi-scale shadow inpainting framework for OCT images by synergically applying sparse representation and deep learning: sparse representation is used to extract features from a small amount of training images for further inpainting and to regularize the image after the multi-scale image fusion, while convolutional neural network (CNN) is employed to enhance the image quality.

Frequency-Aware Physics-Inspired Degradation Model for Real-World Image Super-Resolution

no code implementations5 Nov 2021 Zhenxing Dong, Hong Cao, Wang Shen, Yu Gan, Yuye Ling, Guangtao Zhai, Yikai Su

In particular, we propose to use a convolutional neural network (CNN) to learn the cutoff frequency of real-world degradation process.

Leveraging Deep Learning to Improve the Performance Predictability of Cloud Microservices

no code implementations2 May 2019 Yu Gan, Yanqi Zhang, Kelvin Hu, Dailun Cheng, Yuan He, Meghna Pancholi, Christina Delimitrou

We show that Seer correctly anticipates QoS violations 91% of the time, and avoids the QoS violation to begin with in 84% of cases.
