EXTRACTER: Efficient Texture Matching with Attention and Gradient Enhancing for Large Scale Image Super Resolution

1 code implementation2 Oct 2023 Esteban Reyes-Saldana, Mariano Rivera

Recent Reference-Based image super-resolution (RefSR) has improved SOTA deep methods introducing attention mechanisms to enhance low-resolution images by transferring high-resolution textures from a reference high-resolution image.

Attentive VQ-VAE

no code implementations20 Sep 2023 Angello Hoyos, Mariano Rivera

We present a novel approach to enhance the capabilities of VQ-VAE models through the integration of a Residual Encoder and a Residual Pixel Attention layer, named Attentive Residual Encoder (AREN).

Hadamard Layer to Improve Semantic Segmentation

no code implementations20 Feb 2023 Angello Hoyos, Mariano Rivera

The performance's improvement can be explained by the Hadamard layer forcing the network to produce an internal encoding of the classes so that all bins are active.
