Yuyi Zhang, Yongxin Shi, Peirong Zhang +3
Foundational to the Chinese language and culture, Chinese characters encompass extraordinarily extensive and ever-expanding categories, with the latest Chinese GB18030-2022 standar…
Online Signature Verification based on the Lagrange formulation with 2D and 3D robotic models
Moises Diaz, Miguel A. Ferrer, Juan M. Gil +3
Online Signature Verification commonly relies on function-based features, such as time-sampled horizontal and vertical coordinates, as well as the pressure exerted by the writer, o…
Privacy-Preserving Biometric Verification with Handwritten Random Digit String
Peirong Zhang, Yuliang Liu, Songxuan Lai +2
Handwriting verification has stood as a steadfast identity authentication method for decades. However, this technique risks potential privacy breaches due to the inclusion of perso…
Smaller But Better: Unifying Layout Generation with Smaller Large Language Models
Peirong Zhang, Jiaxin Zhang, Jiahuan Cao +2
We propose LGGPT, an LLM-based model tailored for unified layout generation. First, we propose Arbitrary Layout Instruction (ALI) and Universal Layout Response (ULR) as the uniform…
