Traditional Village Classification Model Based on Transformer Network

The study of traditional villages holds significant implications in cultural, historical, and societal contexts. Despite the considerable research focus on the architectural styles of Qiang, Tibetan, Han, and Hui ethnic villages due to their distinctiveness, rapidly and accurately identifying the types of traditional villages in practical surveys remains a challenge. To address this issue, this paper establishes an aerial image dataset for Qiang, Tibetan, Han, and Hui ethnic villages and introduces a specialized feature extraction network, Transformer-Village, designed for the classification and detection of traditional villages using deep learning algorithms. The overall structure of the network is lightweight, incorporating condconv dynamic convolution as the core layer structure; furthermore, a spatial self-attention-related feature extraction network is designed based on Transformer. In conclusion, through simulated experiments, Transformer-Village coupled with the YOLO detector achieves a 97.2% mAP on the test set, demonstrating superior detection accuracy compared to other baseline models. Overall, the experimental results suggest that this work is feasible and practical

Pyramid-Structured Depth MAP Super-Resolution Based on Deep Dense-Residual Network

© 1994-2012 IEEE. Although deep convolutional neural networks (DCNN) show significant improvement for single depth map (SD) super-resolution (SR) over the traditional counterparts, most SDSR DCNNs do not reuse the hierarchical features for depth map SR resulting in blurred high-resolution (HR) depth maps. They always stack convolutional layers to make network deeper and wider. In addition, most SDSR networks generate HR depth maps at a single level, which is not suitable for large up-sampling factors. To solve these problems, we present pyramid-structured depth map super-resolution based on deep dense-residual network. Specially, our networks are made up of dense residual blocks that use densely connected layers and residual learning to model the mapping between high-frequency residuals and low-resolution (LR) depth map. Furthermore, based on the pyramid structure, our network can progressively generate depth maps of various levels by taking advantages of features from different levels. The proposed network adopts a deep supervision scheme to reduce the difficulty of model training and further improve the performance. The proposed method is evaluated on Middlebury datasets which shows improved performance compared with 6 state-of-the-art methods
