Deformable Convolution

Deformable convolutions are a powerful technique enhancing convolutional neural networks (CNNs) by allowing adaptive sampling of input features, addressing limitations of traditional CNNs with fixed receptive fields. Current research focuses on integrating deformable convolutions into various architectures, including U-Nets, transformers, and state-space models, for applications ranging from image super-resolution and segmentation to 3D shape reconstruction and video processing. This adaptability significantly improves performance in tasks involving complex geometric transformations or irregular object shapes, impacting diverse fields like medical imaging, remote sensing, and autonomous driving. The resulting improvements in accuracy and efficiency are driving significant advancements in these areas.
