本研究探讨计算机视觉中多种特征提取技术，重点分析视觉变压器（ViT）及其他方法，包括生成对抗网络（GANs）、深度特征模型、传统方法（SIFT、SURF、ORB），以及非对比与对比特征模型。聚焦于ViT，报告总结其架构，涵盖分块嵌入、位置编码及多头自注意力机制，并表明其在图像识别任务中表现优于传统卷积神经网络（CNN）。实验评估了各类方法的优劣及其在推进计算机视觉中的实用价值。
原文摘要 · Abstract (English)
This study examines various feature extraction techniques in computer vision, the primary focus of which is on Vision Transformers (ViTs) and other approaches such as Generative Adversarial Networks (GANs), deep feature models, traditional approaches (SIFT, SURF, ORB), and non-contrastive and contrastive feature models. Emphasizing ViTs, the report summarizes their architecture, including patch embedding, positional encoding, and multi-head self-attention mechanisms with which they overperform conventional convolutional neural networks (CNNs). Experimental results determine the merits and limitations of both methods and their utilitarian applications in advancing computer vision.
