ZeroCostDL4Mic: exploiting Google Colab to develop a free and open-source toolbox for Deep-Learning in microscopy

15 June, 2021, 15h30-17h00 CEST (Brussels Time)

Open-source Software

TARGET AUDIENCE

5/5

Bioimage Analysts

ZeroCostDL4Mic is a platform that can be used to train Deep Learning models and, therefore, can be a helpful tool to anyone interested in image analysis.

5/5

Early Career Investigators / Researchers

Using ZeroCostDL4Mic does not require advanced skills and is very well suited for novices and seasoned image analysts alike.

5/5

Facility Staff

The ZeroCostDL4Mic platform is very well suited to Facility Staff who want to train deep learning models for their users.

3/5

Developers

This workshop is primarily aimed at users rather than developers. However, our workshop can be attractive to developers interested in contributing to the platform’s development.

In this NEUBIAS webinar, we will present the ZeroCostDL4Mic platform and showcase how we employ various DL networks, via ZeroCostDL4Mic, to accelerate image analysis and enhance scientific outcomes using a range of biological projects as examples.

This webinar will be divided into 4 sections:

an overview of the platform,

a short demo session about a typical ZeroCostDL4Mic workflow,

a presentation of a range of applications

followed by a second demo session showcasing the integration of interactive segmentation using Kaibu/ImJoy.

 

Abstract: Deep Learning (DL) methods are powerful analytical tools for microscopy and can outperform conventional image processing pipelines. Despite the enthusiasm and innovations fuelled by DL technology, the need to access powerful and compatible resources to train DL networks leads to an accessibility barrier that novice users often find difficult to overcome. Here, we present ZeroCostDL4Mic, an entry-level platform simplifying DL access by leveraging the free, cloud-based computational resources of Google Colab. ZeroCostDL4Mic allows researchers with no coding expertise to train and apply key DL networks to perform tasks including segmentation (using U-Net and StarDist), object detection (using YOLOv2), denoising (using CARE and Noise2Void), super-resolution microscopy (using Deep-STORM), and image-to-image translation (using Label-free prediction – fnet, pix2pix and CycleGAN). Importantly, ZeroCostDL4Mic provide suitable quantitative tools for each network to evaluate model performance, allowing model optimisation. In the Jacquemet laboratory, we use ZeroCostDL4Mic to study cancer cell migration during the different metastatic cascade stages. In particular, we: 1. Use CARE, Noise2VOID, and DecoNoising to improve our noisy live-cell imaging data. 2. Use StarDist and Cellpose together with TrackMate to automatically segment and track migrating cells. In particular, we teamed up with Dr Tinevez to bring deep learning elements to the popular ImageJ plugin TrackMate. 3. Use DRMIME to register microscopy images. In particular, images of zebrafish embryos. 4. Use pix2pix to predict fluorescent labels from brightfield images acquired at high speed.

Learn how to easily train and use neural networks for bioimage analysis using ZeroCostDL4Mic

Presenters:

Guillaume Jacquemet is group leader at Abo Akademi University (Turku, Finland). His lab studies the mechanism underlying cancer cell migration and invasion.

TARGET AUDIENCE

5/5

Early Career Investigators

Will learn how to parallelize ImageJ macros. Will learn about ImgLib2, the N5 API, Spark, BDV, and Paintera.

4/5

Facility Staff

Will learn how to parallelize ImageJ macros and how process SPIM data on a cluster. Will get a better idea about the advantages and shortcomings of N5 supported formats and requirements for storage hardware and analysis software.

4/5

Bioimage Analysts

5/5

Developers

Will get a glimpse of what can be done to parallelise processing of many large images with OpenMPI and what are the limitations of the approach. Will learn about Stephan’s perspective on how to develop and parallelize processing workflows.

PART 1.  30 min

Processing large images on a cluster from within Fiji We have developed a brige between Fiji and OpenMPI to enable parallel processing of many, large and many large images on an HPC resource.

We will cover three distinct topics:

1) We will show how to realize parallelization of a very specific task, namely multi-view light sheet data registration and fusion, on a HPC resource through a dedicated web interface.

2) We will explain how one can spread an arbitrary Macro-mediated processing task on many relatively small images onto an HPC resource using specialized ImageJ parallel macro commands and monitor the progress and results.

3) We will demonstrate how to deploy specialized (syntactically identical) ImageJ2 Ops commands to parallelise processing of a single large image split into smaller chunks on an HPC resource.

Finally, we will show how one can combine 2) and 3) to process many large images by first grouping them with paralllel macro and then processing on the groups in parallel using the ImageJ2 Ops. This allows, for example, processing of long-term time-lapse 3D image data. We will discuss the limitations of this approach.

PART 2. 1h

Large data processing and visualization with ImgLib2, N5, Spark, BigDataViewer, and Paintera (40 + 5 min) Learn to create lazy processing workflows with ImgLib2, using the N5 API for storing and loading large n-dimensional datasets, and how to parallelize such processing workflows on a multi-threaded computer and on compute clusters using Spark. You will see how to use BigDataViewer to visualize and test processing results, and we will prepare projects for manual annotation/ proofreading with Paintera.

1. Gain awareness of published solutions for parallel SPIM image processing. Understand how to parallelize recorded Fiji macros to process many small images on a cluster. Become aware of the possibilities to use ImageJ2 Ops to process single large images. See how it can in principle be all combined together. Understand the limitations of the approach.

2. Use the N5 API to store large n-dimensional data on local filesystems or cloud storage using the formats N5, HDF5 and Zarr. Understand how to use ImgLib2 cache to speed up lazy transformation and processing for both visualization and analysis. Use local multi-threading to parallelize processing. Set up and use Spark to parallelize processing on a compute cluster. Prepare datasets for annotation with Paintera.

Developers

To get the high level concepts. Overview of related projects in the Fiji/ImageJ universe..

In this webinar, we will present concepts, challenges and solutions related to big image data.

The presented solutions are part of the emerging FIJI BigDataViewer ecosystem.

The webinar is structured in four parts: a general introduction to the concepts of big image data, followed by a presentation of three tools.

We first discuss the challenges of representing, storing, visualizing, and processing such data, and how these challenges are addressed in Fiji.

Second, we will demo the BigDataViewer user interface. This provides a basic way to interact with big images, multi-modal images, microscopy datasets with multiple angles or tiles, etc.

A third part will be dedicated to easily opening, navigating and exporting your data thanks to a module called BigDataViewer-Playground. Multi-resolution support through Bio-Formats and BigDataViewer caching allow to navigate big 5D data without the need of converting files in most cases. BigDataViewer-Playground can thus be used as an entry point for other modules of the ecosystem such as BigStitcher, BigWarp, etc.

Finally, we will demonstrate BigDataProcessor2 (BDP2). With BDP2 you can open (TB sized) prevalent light-sheet and volume EM data formats and interactively apply typical image pre-processing operations such as cropping, binning, chromatic shift and non-orthogonal acquisition correction. The processed data can be re-saved for downstream image analysis.

Learn the concepts and the possibilities behind BigDataViewer. Learn how to open and convert your data and make it ready for BigDataViewer.

In this webinar, we will first present advanced colocalization methods for analyzing SMLM data, before introducing statistical tools for analyzing the spatial distribution of objects.

Part1: By generating point clouds instead of images, SMLM has necessitated the development of dedicated colocalization methods. In the first part of the webinar, we will present several density-based methods computing colocalization estimators directly from the localization coordinates.

Part 2: The second part of the webinar will be dedicated to object-based colocalization methods, with a strong focus on robust statistical analysis. This analysis applies to any type of microscope image (from cryo-em and SMLM to widefield imaging), providing that the positions of the objects (molecules, cells…) can be estimated. 

At the end of the webinar, participants will have a good knowledge of advanced colocalization methods for analyzing SMLM data, and spatial statistics for characterizing the spatial distribution of molecular assemblies in a wide range of imaging modalities.

Basic knowledge of SMLM is a plus.

Early Career Investigators

You’ve been asked by your PI you SHOULD do co-localization but are having a hard time understanding all this mess ? Here is a starting point.

The Webinar will be broadcasted live with Zoom, in the form of an interactive webinar with Questions&Answers. Attendance will be limited to 3000 participants.

Questions will be live-moderated, Q&As will be further reported in a note file shared with attendants. Registered participants will receive a link to connect live. The event will be recorded for further viewing and stored on NEUBIAS Youtube Channel.

Co-localization analysis is a one of the main interest of users entering a Facility with slides in hand and nice analysis perspectives in mind. While being available through most, if not all, analysis software, co-localization tools are mainly perceived as black boxes, fed with images and excreting (the expected) numbers. A large bunch of papers have been trying to push forward one method which would perform better than all the others, losing the focus from the variety of biological problematics which may explain why so many methods exist nowadays. In this talk, we will aim at deconstructing existing generic co-localization workflows. By differentiating work-cases, identifying co-localization reporters and the metrics others have been using, we aim at providing the audience with the elementary bricks and methods to build their really own co-localization workflows.

After attending this webinar, participants will be get a better understanding of the most commonly used metric for co-localization. By getting a deeper insight of what lies behind indicators and quantifiers, they are expected to make an appropriate choice when picking a co-localization method or get new ideas to developed metrics more suited to their own problematics.

No specific prior knowledge is required.
