复现点:
1 paper: reading text in the wild with deep convolutional neural network
论文阅读笔记:论文阅读:Reading Text in the Wild with Convolutional Neural Networks,
部分代码为code|matlab

文章的主要思想为先利用region proposal产生出足够多的候选区域,再resize这些候选框到固定大小,用一个CNN来对这些候选框进行单词的分类,超过90k个单词。使用生成的带文本的图片的方法,能够保证文本单词的样本量。
思路很清晰,限制条件也很明显,不能出现样本外的单词,诸如一些合成词;此外,候选框也需要完整地包含单词。
