cellstitch-cuda 1.0.0

CUDA-accelerated CellStitch 3D labeling using Instanseg segmentation.

CellStitch-Cuda: CUDA-accelerated CellStitch 3D labeling.

About this repo

An overhaul of the CellStitch algorithm, developed by Yining Liu and Yinuo Jin (original repository), publication can be found here.

Some major adjustments:

• Replaced NumPy with CuPy for GPU-accelerated calculations.
• Replaced nested for-loops with vectorized calculations for dramatic speedups (~100x).
• Included novel segmentation method InstanSeg, which enables multichannel inputs (repo and publication).
• An all-in-one method that takes an ZCYX-formatted .tif file, performs the correct transposes, and writes stitched labels.
• Included a histogram-based bleach correction to adjust for signal degradation over the Z-axis (originally developed for ImageJ in (Miura 2020) and released for Python by marx-alex in napari-bleach-correct).

Some comparisons

Installation

Notes

This setup has so far only been verified on Windows-based, CUDA-accelerated machines. Testing has only been performed on CUDA 12.x. There are no reasons why 11.x should not work (check instructions), but your mileage may vary.

Conda setup

conda create -n cellstitch-instanseg python=3.9
conda activate cellstitch-instanseg

Clone repo and install

conda install git
git clone https://github.com/Tomvl117/cellstitch-instanseg.git
cd cellstitch-instanseg
pip install -e .
conda install pytorch pytorch-cuda=12.1 -c conda-forge -c pytorch -c nvidia

You may replace the version number for pytorch-cuda with whatever is applicable for you.

Additional steps for CUDA 11.x

pip uninstall cupy-cuda12x
pip install cupy-cuda11x

Instructions

From an image

from cellstitch_cuda.pipeline import cellstitch_cuda

img = "path/to/image.tif"
# or feed img as a numpy ndarray

3d_masks = cellstitch_cuda(img)

From pre-existing orthogonal labels

from cellstitch_cuda.pipeline import full_stitch

# Define xy_masks, yz_masks, xz_masks in some way

3d_masks = full_stitch(xy_masks, yz_masks, xz_masks)
