Abstract
A method for the automatic recognition of offline handwritten signatures using both global and local features is described. As global features, we use the envelope of the signature sequenced as polar coordinates; and as local features we use points located inside the envelope that describe the density or distribution of signature strokes. Each feature is processed as a sequence by a hidden Markov Model (HMM) classifier. The results of both classifiers are linearly combined, obtaining a recognition ratio of 95.15% with a database of 60 handwritten signatures

  • Pretraining has recently greatly promoted the development of natural language processing (NLP)
  • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
  • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
  • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
  • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance

要点】:本文提出了一种结合全局特征(签名外轮廓)和局部特征(笔迹分布)的手写签名自动识别方法,使用隐马尔可夫模型(HMM)进行分类,实现了95.15%的识别率。

方法】:通过将签名外轮廓转换为极坐标序列作为全局特征,并将签名内部点描述的笔迹密度或分布作为局部特征,使用HMM分类器处理每种特征序列。

实验】:在包含60个手写签名的数据库上进行实验,通过线性组合全局和局部特征分类器的结果,达到了95.15%的识别率。
