機械学習及び Watershed 画像領域分割法の組み合わせを用いた
位相差顕微鏡画像の自動細胞計数法

I. 研究の背景・問題点

生物画像の解析では、像の自動分類やノイズ除去、領域分割、物体追跡、クラスタリングを始め、様々なところで機械学習が広く利用されています。
機械学習は、情報科学、確率・統計、数理最適化、統計物理学など、多くの分野に関わっています。そして、画像処理、情報推薦システム、バイオインフォマティクス、医用画像分析、細胞画像情報の分析など、幅広い分野において威力を発揮しています。
これまでコンピュータビジョンの分野では様々な画像解析手法が提案されてきたが、これらを生物画像に直接適用することは困難であります。
例えば、生物画像は画像中に色ムラやノイズを含んでいるケースも多く、また個々の細胞が単なる輝点でしか表わされないことも多いため、細胞同士が重なっている場合にうまく分離できない場合があります。

II. 研究目的・内容

的情報処理を獲得することです。本研究中、位相差法による顕微鏡画像での細胞計数を研究することを目的としています。
この研究内容は、以下の分野に焦点を当てています。密集した細胞の画像を解析するための細胞分割法を提案します。
この手法ではマーカ制御のWatershed 変換と畳み込みニューラルネットワーク(CNN)を組み合わせたものです。難易度の高いモダリティにおいて、密集した細胞集団をセグメント化します。Watershed 変換と深層学習を組み合わせることを提案します。
そこで、機械学習に入力するデータとして、これらを学習させることで、細胞の画像と細胞の計数関係性を学習させて、画像から自動で細胞追跡の判定解析が可能となることが期待されます。

肝臓の超音波検査映像にからの腫瘍及び肝内物体の検出

肝がんのスクリーニング検査の一つとしてよく超音波検査が用いられている。

超音波検査はCT検査やMRI検査と比較して非侵襲性で簡便に実施でき、リアルタイムに肝臓を観察可能な検査方法である。

ただ、肝臓の超音波検査から正確に腫瘍の所在地の把握や小さい腫瘍を見逃しなく発見するには、医学的知識だけでなく熟練の経験が求められる。

研究室では肝臓の超音波検査をサポートするために肝臓内の腫瘍及び血管等を検出することで医師の超音波検査を支援するシステム開発を行っている。

深層学習をベースとして検出モデルを構築しておりリアルタイムに肝臓の超音波検査映像から腫瘍、グリソン鞘、下大静脈、下行大動脈、肝静脈を検出することができる。

冷凍空調の分野ではエアコン使用時に起こる冷媒漏洩問題や廃棄時の回収率が低い問題で環境に優しい新冷媒の開発が求められている。
