Web考虑到将Faster R-CNN 用于文本检测时,矩形锚点框与文本的形状相差过大,会导致区域生成网络(region proposal network,RPN)在生成文本候选区域时效率不高,鲁棒性也不强,Zhong 等人(2024)因此借鉴了DenseBox(Huang 等,2015) 的思想,提出了不需要锚点框的区域生成网络(anchor-free region proposal network, AF-RPN)。 WebOct 17, 2024 · Implementation of Connectionist Text Proposal Network (CTPN) In the previous blog we have learnt about CTPN algorithm and its architecture in detail. In this blog we will implement this algorithm using its GitHub repository to localize text in an image. We will use Linux operating system to do this. Clone the Repository damen annecy down mantel

It is a class of algorithms to select one entity (e.g. bounding boxes) out of many overlapping entities. -source Reflections on Non Maximum Suppression (NMS) by Subrata Goswami Medium. Here we will use Locally Aware NMS. It adds weighted … WebOct 19, 2024 · This algorithm consists of a fully convolutional network with a non-max suppression (NMS) merging state. The fully convolutional network is used to localize text in the image and this NMS stage is basically used to merge many imprecise detected text boxes into a single bounding box for every text region (word or line text). birdlife thurgau
