Cell Detection in Domain Shift Problem Using Pseudo-Cell-Position Heatmap

2 code implementations19 Jul 2021 Hyeonwoo Cho, Kazuya Nishimura, Kazuhide Watanabe, Ryoma Bise

We propose an unsupervised domain adaptation method for cell detection using the pseudo-cell-position heatmap, where a cell centroid becomes a peak with a Gaussian distribution in the map.

Weakly-Supervised Cell Tracking via Backward-and-Forward Propagation

1 code implementation ECCV 2020 Kazuya Nishimura, Junya Hayashida, Chenyang Wang, Dai Fei Elmer Ker, Ryoma Bise

We propose a weakly-supervised cell tracking method that can train a convolutional neural network (CNN) by using only the annotation of "cell detection" (i. e., the coordinates of cell positions) without association information, in which cell positions can be easily obtained by nuclear staining.

Spatial-Temporal Mitosis Detection in Phase-Contrast Microscopy via Likelihood Map Estimation by 3DCNN

3 code implementations27 Apr 2020 Kazuya Nishimura, Ryoma Bise

In this paper, we propose a novel mitosis detection method that can detect multiple mitosis events in a candidate sequence and mitigate the human annotation gap via estimating a spatiotemporal likelihood map by 3DCNN.

MPM: Joint Representation of Motion and Position Map for Cell Tracking

3 code implementations CVPR 2020 Junya Hayashida, Kazuya Nishimura, Ryoma Bise

Conventional cell tracking methods detect multiple cells in each frame (detection) and then associate the detection results in successive time-frames (association).

Weakly Supervised Cell Instance Segmentation by Propagating from Detection Response

1 code implementation29 Nov 2019 Kazuya Nishimura, Dai Fei Elmer Ker, Ryoma Bise

In addition, we demonstrated that our method can perform without any annotation by using fluorescence images that cell nuclear were stained as training data.
