摘要
DNA机器人是一种由DNA大分子通过折纸技术制作的纳米级别的机器人,可以用于癌症的诊断和治疗。为了对DNA机器人形态进行研究,研究人员利用原子力显微镜(Atomic Force Microscope,AFM)拍摄出机器人的AFM图像。针对AFM图像多噪声及被观察的DNA机器人大规模重叠的特点,从除噪、分割、识别三个过程展开,提出了一种基于多尺度改进的分水岭AFM图像切割算法,以傅里叶描述子、曲率尺度空间描述符和Hu矩作为特征,实现DNA纳米机器人的分类和识别。
DNA robot is a type of nano robots made from DNA macromolecules with the origami technology. DNA robots can be used for the diagnosis and treatment of the cancer. To research the DNA robots, Atomic Force Microscope(AFM)is used to take the photographs of the DNA robots. Since there are many noises in the AFM images and overlaps among the DNA robots, removing noises, segmentation, and recognition are processed. The watershed based on multiscale technique is improved for the segmentation of DNA robots. DNA robots are classified and recognized with the Fourier descriptors, Curvature Scale Space(CSS)method and Hu moment.
