On the Matrix Form of the Quaternion Fourier Transform and Quaternion Convolution

no code implementations4 Jul 2023 Giorgos Sfikas, George Retsinas

We focus especially on the relation of Quaternion Fourier Transform matrices to Quaternion Circulant matrices (representing quaternionic convolution), and the eigenstructure of the latter.

WordStylist: Styled Verbatim Handwritten Text Generation with Latent Diffusion Models

1 code implementation29 Mar 2023 Konstantina Nikolaidou, George Retsinas, Vincent Christlein, Mathias Seuret, Giorgos Sfikas, Elisa Barney Smith, Hamam Mokayed, Marcus Liwicki

Our proposed method is able to generate realistic word image samples from different writer styles, by using class index styles and text content prompts without the need of adversarial training, writer recognition, or text recognition.

Trainable Learning Rate

no code implementations29 Sep 2021 George Retsinas, Giorgos Sfikas, Panagiotis Filntisis, Petros Maragos

Selecting an appropriate learning rate for efficiently training deep neural networks is a difficult process that can be affected by numerous parameters, such as the dataset, the model architecture or even the batch size.

WSRNet: Joint Spotting and Recognition of Handwritten Words

no code implementations17 Aug 2020 George Retsinas, Giorgos Sfikas, Petros Maragos

The related joint loss leads to a boost in recognition performance, while the Seq2Seq branch is used to create efficient word representations.
