FAST: Font-Agnostic Scene Text Editing

no code implementations5 Aug 2023 Alloy Das, Prasun Roy, Saumik Bhattacharya, Subhankar Ghosh, Umapada Pal, Michael Blumenstein

However, most of the existing STE methods show inferior editing performance because of (1) complex image backgrounds, (2) various font styles, and (3) varying word lengths within the text.

Shared and Private VAEs with Generative Replay for Continual Learning

1 code implementation17 May 2021 Subhankar Ghosh

We propose a hybrid continual learning model that is more suitable in real case scenarios to address the issues that has a task-invariant shared variational autoencoder and T task-specific variational autoencoders.
