Despite the rapid development of nanoscience and nanotechnology in various fields, the high cost associated with obtaining a sufficient number of nano-object samples remains a challenge, impeding the advancement of deep learning methods in the materials domain. To address this issue, we have designed a novel method for identifying nano-objects in atomic force microscopy (AFM) images. Firstly, we employ a LOG-based image denoising technique for preprocessing the images. Then, we propose two improved methods for segmenting overlapping objects based on the watershed algorithm. Finally, we establish a transfer learning-based convolutional neural network (CNN) recognition model. This model achieves excellent performance by pretraining on large-scale datasets of handwritten digits and letter shapes, enabling the identification of nano-objects in AFM images. The method proposed in this study effectively tackles the challenge of identifying nano-objects in AFM images, where the availability of small-sample nano-objects is limited.
