Application of deep neural networks for military symbol recognition from sketch images

The purpose of this research is to test the effectiveness of deep neural networks in recognizing sketch images, particularly military symbols. Sketch images are highly abstract and lack typical features of real images, such as color, background, and environmental details, making the use of deep neural networks a significant challenge. To address this issue, we implement a sketch image recognition model based on Convolutional Neural Networks (CNN). The content of the paper includes designing and describing a new CNN model optimized for symbol recognition from sketch images. We have trained this model on a dataset self-constructed by our team. The training results show that the model has high accuracy in recognizing military symbols from sketch images, confirming the potential of deep neural networks in this field.
