描述

EasyDeepOCR是一款新一代OCR库,依托深度学习技术应对当今文本识别领域的挑战。图像中的文本检测与字符识别均实现全自动化处理。借助文本拓扑结构,可有效降低字符歧义性并过滤无关文本。仅需少量样本的优化流程能显著提升处理速度。 相较于EasyOCR和EasyOCR2库,EasyDeepOCR实现了重大突破,在保持易用性的同时显著增强了功能。 

EasyDeepOCR Picture1

简单API,却能带来惊艳效果

只需一次“读取”调用,图像中的所有文本都将被检测并读取。无需再设置复杂的配置。

EasyDeepOCR Picture3

优化操作以加快处理速度

处理管道优化功能可提升读取速度。用户需标注若干样本图像(通常为1至3张),随后EasyDeepOCR将自动选择能缩短处理时间的内部参数。

EasyDeepOCR Picture4

功能齐全的全新New Open eVision Studio工具

New Open eVision Studio中的EasyDeepOCR工具全面展现了该库的所有功能。用户可选择拓扑结构,并对部分样本图像进行标注以实现管道优化。深度学习执行设置可供选择,支持在不同设备(CPU、GPU)和引擎(OpenVINO、TensorRT等)间进行切换。

拓扑学定义:聚焦于正确的文本

拓扑结构定义了目标文本的格式。在工业标记领域,拓扑结构具有极高的实用价值,可重点呈现有效期、零件编号或其他格式要求严格的文本。通过定义拓扑结构,用户不仅能获取所需文本,还能通过减少歧义来提升字符识别精度。

EasyDeepOCR Picture2

在CPU(英特尔OpenVINO)和GPU(英伟达TensorRT)上表现优异

EasyDeepOCR已针对英特尔和ARM处理器(得益于OpenVINO)以及NVIDIA显卡(得益于TensorRT)进行了优化。

New Open eVision Studio

复杂的图像处理序列可通过图形界面进行设计。该工具集充分展现了Open eVision库的多样性与强大功能。对应处理管道的C++、Python和C#源代码将自动生成,并提供Open eVision API的交互式文档。New Open eVision Studio可处理实时图像源,例如千兆网Vision相机、Coaxlink图像采集卡或eGrabber录像序列。

本应用免费提供,支持Windows与Linux系统,兼容英特尔及ARM 64位架构。
