虽然已经研究了人工气味感测系统，但是我们研究了使用表达昆虫ORs（嗅觉受体）的生物细胞的气味感测系统。由于生物活细胞的性质，昆虫OR具有优异的灵敏度和选择性。我们制作了一套荧光测量系统，可以捕捉生物细胞的荧光图像。然而，由于荧光非常弱，所以它容易受到噪声的影响。在本研究中，我们专注于图像处理技术，从整个图像中提取具有荧光变化的细胞区域。实验结果表明，该方法提高了图像的信噪比。
Although an artificial odor sensing system has been studied, we studied the odor sensing system using biological cells expressing insect ORs (Olfactory Receptors). An insect OR has excellent sensitivity and selectivity owing to the nature of biological living cell. We made the fluorescent measurement system capturing fluorescent image of biological cells. However, it is easily influenced by noise since the fluorescent light is very weak. In the present study, we focused on the image processing technique to extract the cell area with fluorescent change from the entire image. The experimental result suggests signal to noise ratio was improved by this technique.
