Upsample Anything: A Simple and Hard to Beat Baseline for Feature Upsampling

arXiv — cs.CVTuesday, November 25, 2025 at 5:00:00 AM
  • The introduction of the 'Upsample Anything' framework offers a lightweight test-time optimization solution that enhances low-resolution features to high-resolution outputs without requiring prior training. This method addresses the limitations of existing feature upsampling techniques, which often necessitate dataset-specific retraining or complex optimization processes.
  • This development is significant as it allows for improved scalability and generalization of Vision Foundation Models, which are commonly downsampled in pixel-level applications. By utilizing a learned anisotropic Gaussian kernel, the framework enhances the precision of feature restoration across various architectures and modalities.
  • The emergence of 'Upsample Anything' aligns with ongoing advancements in the field of computer vision, particularly in feature upsampling and Gaussian Splatting techniques. As researchers explore innovative methods like Neighborhood Attention Filtering and low-rank tensor representations, the focus remains on overcoming challenges such as overfitting and enhancing multi-dimensional image recovery, indicating a broader trend towards more efficient and adaptable AI frameworks.
