一种基于小波变换与分水岭变换的菌落图像分割算法研究

菌落的特点是菌落细胞大小不一、形态各异、分布杂乱。提出了一种新的基于小波变换与分水岭变换的分割算法，首先利用小波变换产生多分辨率图象，然后对最低分辨率图象进行分水岭分割，最后对低分辨率分割后的图象进行高分辨率投影，得到高分辨率图象的分水岭分割结果。实验结果表明，该算法对复杂菌落图象能获得较好的分割效果。

Study of colony image segmentation algorithm based on wavelet transform and watershed transform

The colonies are different in size and shape and disordered distributing. A new segmentation algorithm based on the wavelet transform and watershed transform is presented. Firstly, wavelet transform was used to create multi-resolution images. Then watershed segmentation algorithm was applied to segment the lowest-resolution image and get the initial watershed segmentation. Finally, the low resolution segmentation was projected to high-resolution to get the full-resolution image. Experiments results show that the colony images can be well segmented by the new algorithm.
