特征提取技术是计算机视觉以及图像处理领域的一个研究热点，在各领域都取得了较为显著的应用成效。本文从舰船图像轮廓特征提取入手，通过正交化各类投影子空间，设计出一个舰船图像轮廓特征的二元损失函数，不断优化识别检测算法，验证本次基于子空间投影的舰船图像轮廓特征提取方法的分类性能与泛化能力。
Object detection technology is a research hotspot in the fields of computer vision and image processing, with rapid development in both theoretical research and practical applications, and has achieved significant application results in various fields. Therefore, this paper will try to start with the extraction of ship image contour features, design a binary loss function of ship image contour features by orthogonalization various projection spaces, constantly optimize the recognition and detection algorithm, and verify the classification performance and generalization ability of this ship image contour feature extraction method based on subspace projection.
