从craft 到 text reader ,相关的处理方法也有很多了。不过这篇文章的处理还是很有意思的,还是仔细的提一下 首先,半监督的训练的思路都是,首先在具有单字坐标位置标注的合成数据上进行训练,使得模型具有基本的能力 有空的时候我也把我的具有单字坐标的数据合成代码甩出来好了 随后,对于那些只有文本行标注,没有单字...
Handwritten text line recognition is difficult because the characters in text line cannot be reliably segmented prior to character recognition. This chapter introduces the general integrated segmentation-and-recognition framework for handwritten Chinese text line recognition. In the framework, on classifying ...

This paper presents an effective approach for the offline recognition of unconstrained handwritten Chinese texts. Under the general integrated segmentation-and-recognition framework with character oversegmentation, we investigate three important issues: candidate path evaluation, path search, and parameter estim...
This paper investigates the effects of employing common sense knowledge as a new linguistic context in handwritten Chinese text recognition. Three methods are introduced to supplement the standard n-gram language model: embedding model, direct model, and an ensemble of these two. The embedding model...
Handwritten Chinese Text Recognition (HCTR) has been advanced largely by deep learning in recent years. However, the remaining recognition errors still hinder reliability-critical applications where zero-error is desired. Rejecting low-confidence patterns can help reduce the error rate but the increased...
This paper proposes a method for handwritten Chinese/Japanese text (character string) recognition based on semi-Markov conditional random fields (semi-CRFs). The high-order semi-CRF model is defined on a lattice containing all possible segmentation-recognition hypotheses of a string to elegantly fuse...
Faster Segmentation-Free Handwritten Chinese Text Recognition with Character Decompositions 来自 Semantic Scholar 喜欢 1 阅读量: 174 作者:T Bluche,R Messina 摘要: Recently, segmentation-free methods for handwritten Chinese text were proposed. They do not require character-level annotations to be trained...
A Chinese handwritten text dataset, HIT-MW, is presented to facilitate the offline Chinese handwritten text recognition. Texts for handcopying are sampled from China Daily corpus with a stratified random manner. To collect naturally written handwriting, forms are distributed by postal mail or middleman...
When we started looking into the large-scale recognition of Chinese characters some time ago, CNNs seemed to be the obvious choice. But that approach required scaling up CNNs to a set of approximately 30,000 characters, while simultaneously maintaining real-time performance on embedded devices. ...
