ViTEraser: Harnessing the Power of Vision Transformers for Scene Text Removal with SegMIM Pretraining

1 code implementation21 Jun 2023 Dezhi Peng, Chongyu Liu, Yuliang Liu, Lianwen Jin

As ViTEraser implicitly integrates text localization and inpainting, we propose a novel end-to-end pretraining method, termed SegMIM, which focuses the encoder and decoder on the text box segmentation and masked image modeling tasks, respectively.

Towards Robust Tampered Text Detection in Document Image: New Dataset and New Solution

1 code implementation CVPR 2023 Chenfan Qu, Chongyu Liu, Yuliang Liu, Xinhong Chen, Dezhi Peng, Fengjun Guo, Lianwen Jin

In this paper, we propose a novel framework to capture more fine-grained clues in complex scenarios for tampered text detection, termed as Document Tampering Detector (DTD), which consists of a Frequency Perception Head (FPH) to compensate the deficiencies caused by the inconspicuous visual features, and a Multi-view Iterative Decoder (MID) for fully utilizing the information of features in different scales.
