基于图像处理的分支链氨基酸菌体形状识别

Bacterium Body Shape Recognition of Branched Chain Amino Acid Based on Image Processing

提出了一种用于分支链氨基酸发酵过程中菌体形状识别的方法。该方法基于菌体的图像,充分利用菌体的形状特征,将菌体图像的面积作为第一步识别特征,然后将菌体中心的位置作为第二步识别特征,最后对菌体图像进行编码作为第三步识别特征。实验表明,该方法可以对分支链氨基酸发酵过程中的菌体形状进行准确快速的识别。

A method of recognizing body shapes of bacteria during fermentation process of branched chain amino acid （BCAA） was proposed, which is based on the images of bacteria. In order to fully make use of shape properties of bacteria, the areas of bacteria were used for the first-step recognition. Then, the positions of the centers of bacterium images were used for the second-step recognition. Finally, the images of bacteria were coded for the third-step recognition. Recognition experiments were conducted with satisfied results to show the proposed method recognizes the shapes of bacteria during fermentation process of BCAA correctly and fast.
