Apr 15, 2024 · In this paper, we propose a memristor-based software–hardware collaborative image restoration method, named MWA-MNN. It consists of three sub-networks, each of which comprises DWAB, CCAB, and SSKB that extract and select rich contextual information.

In this paper, we present a novel multi-level wavelet CNN (MWCNN) model for better tradeoff between receptive field size and computational efficiency. With the modified U-Net architecture, wavelet transform is introduced to reduce the size of feature maps in the contracting subnetwork.

Sep 21, 2023 · The MWA is special for its very wide field of view, high angular resolution, nanosecond time resolution, and digital pointing agility. This makes the instrument invaluable for quickly mapping the sky and studying rare and faint events as they happen. Explore some of our key science drivers here.

As previously mentioned, the image associated with the acronym MWA is formatted in PNG, which stands for Portable Network Graphics. This image has specific dimensions, with a length of 669 pixels and a width of 350 pixels. The file size of the image is approximately 60 kilobytes.

The wide primary beam of the MWA is modelled and calibrated out, and the flux scale is tied to existing catalogues. Data. The first release images from the GLEAM survey (Wayth et al. 2015) cover the extragalactic sky (minus the Galactic plane) these are available via SkyView. Details of the image processing are given in Hurley-Walker et al. (2017)

MWCNN for image restoration is based on U-Net architecture, and inverse wavelet transform (IWT) is deployed to reconstruct the high resolution (HR) feature maps.

Mar 22, 2023 · We replace the attention in ViT with MWA and our experiments with CIFAR and Tiny-ImageNet classification demonstrate significant improvement over alternative Fourier-based attentions such as AFNO and Global Filter Network (GFN).
