隨著高齡化社會的來臨,腦科學的研究日趨受到重視,但人類大腦複雜、不易研究,使得果蠅腦在生物領域被廣為應用。生物學家希望透過相異表現型的果蠅腦神經細胞分割與計數來了解腦神經細胞的發育、運作與型態改變之情形,但在共軛焦顯微螢光影像內辨識細胞並不容易,尤其是在缺少標記的分割標準答案下,即使有很多基於U-net基礎的分割卷積神經網路(convolutional neural networks, CNNs),我們仍無法利用現有的深度神經網路方法對共軛焦顯微螢光影像內的特定細胞進行有效的影像辨識與影像分割。
在過去的研究中,ImageJ軟體是進行手動預處理與人工標記最常見的工具,但其耗時費力且容易受到人為因素影響標記結果的準確性,因此,使用ImageJ半手動標記的結果仍然不夠精確。為了解決人工標記所致的問題與誤差,本文提出了一種利用卷積的神經細胞辨識和計數運算。透過實驗結果顯示,在沒有分割標準答案的情況下,我們的方法相較輔助軟體的人工標記結果來得更穩定且有效率。
With the advent of an aging society, the research of brain science has been paid more and more attention. However, the human brain is complex and difficult to study, making the Drosophila (fruit fly) brain widely used in the biological field. Biologists want to explore the mechanism of the development, the operation, and the morphological changes of brain nervous system by segmenting and counting neural cells differentiated from neuroblasts in different Drosophila phenotypes’ brain. However, it is difficult to identify cells in confocal fluorescence microscopy images. Although there are several benchmark segmentation convolutional neural networks (CNNs) based on U-net, they cannot function successfully in the absence of labeled segmentation ground truth. Hence, we cannot use the existing deep neural network methods to effectively identify and segment specific cells in the confocal fluorescence microscopy image.
Conventionally, the ImageJ software is the mostly used tool for manual preprocessing and manual labeling, but it is time-consuming, laborious, and sensitive to user-specified configurations. Therefore, the semi-manual labeling result suggested by ImageJ is still not accurate enough. To solve the problems and fix errors caused by manual labeling, we propose in this paper a convolution-based algorithm for neural cell recognizing and counting. The experimental results show that our method is more stable and more efficient than the software-assisted manual labeling result, especially in the absence of segmentation ground truth.
