A Convolutional Vision Transformer for Semantic Segmentation of Side-Scan Sonar Data

1 code implementation24 Feb 2023 Hayat Rajani, Nuno Gracias, Rafael Garcia

To overcome the lack of CNN-like inductive biases, thereby making ViTs more conducive to applications in low data regimes, we propose a novel feature extraction module to replace the Multi-layer Perceptron (MLP) block within transformer layers and a novel module to extract multiscale patch embeddings.
