| 研究実績の概要 |
研究の目的 To goal of the project is to develop an image processing pipeline that uses computational tools, including deep learning, to automate image analyses of Alzheimer's disease microscopy images.
研究実施計画 For FY2022 and FY2023, the 2 goals are to use computational tools to automatically preprocess microscopy images of AD mouse brain, and to segment, quantify, and conduct morphological feature analysis of Ab plaques. I have developed image preprocessing pipelines to preprocess 2D AD images from the original collaborator, as well as 3D images from a new collaborator. I developed an automated workflow for processing gene expression images, which was accepted as a peer-reviewed conference paper; the computational tools developed for this work can be applied to the 若手 project. In collaboration with other lab members, we developed novel methods to conduct instant segmentation of sparse, punctate objects; this work was submitted as for peer-review at 2 other conferences.

3: やや遅れている
理由
As planned, I have focused on preprocessing and plaque processing steps.
However, with the addition of data from an additional collaborator, it is evident that image profiles from different labs can vary greatly. For example, images' SNR, background staining, 2D vs 3D, what cells/objects are stained for, etc. Because the goal is to create a generalized processing pipeline for AD microscopy images, it is now obvious that more time should be allocated to develop ways to improve generalization.
I had planned for 1 publication per year, but current results are too specific to the datasets. Instead, in collaboration with other lab members, we have submitted 3 peer-reviewed conference papers to describe methods that we have been developing, which are applicable for this project.

| 今後の研究の推進方策 |
Data from more collaborators should be solicited earlier to test the generalizability of the pipeline. This will be done at the JNS conference this year.
I had planned for 1 publication per year. However, it now seems more effective to plan for a publication that summarizes the entire pipeline at the end of the project. If appropriate, findings from each FY can be submitted as peer-reviewed conference proceeding papers, as was done this year.
