超高分辨率图像的下采样分割

http://lxasqjc.github.io/learn-downsample.github.io/
We introduced an approach for learning to downscale high-resolution images for segmentation tasks. The main motivation was to adapt the sampling budget to the difficulty of segmented pixels or regions. We showed that learning the spatially varying downsampling strategy jointly with segmentation offered advantages in segmenting large images with a limited computational budget.

作为主要作者,我全权负责开发工作. This work was published at ICLR 2022.

百万像素组织学图像的注视点分割

http://chenjin.netlify.app/publication/foveation/
Segmenting ultra-high resolution images often needs empirical decisions on the trade-off patch configuration between field-of-view (FoV) — spatial coverage — and the image resolution. We introduced the foveation module, a jointly learnable data loader which, for a given ultra-high resolution image, adaptively chooses the appropriate configuration (FoV or resolution trade-off) of the input patch to feed to the downstream segmentation model at each spatial location of the image.

这项工作发表在MICCAI 2020上,我是监督开发的主要作者.

超高分辨率图像的注视点分割

http://chenjin.netlify.app/publication/foveation_ultrahigh/
在MICCAI 2020之前的创新工作之上, in this extended version, we further introduced the more computational efficient hard-gated categorical sampling of FoV-resolution patch configurations at each location and provided two differentiable solutions. 我们演示了三个远景基准的一般适用性, including Cityscapes autopilot images, DeepGlobe aerial images, and Gleason2019 histopathology images.

作为监督整个开发过程的主要作者,我在Arxiv上发表了这项工作.
