Java調用百度OCR文字識別API實現圖片文字識別軟件

這是一款小巧方便，強大的文字識別軟件，由Java編寫，配上了窗口界面

調用了百度ocr文字識別API 識別精度高。

更新日志

新的改變 OcrViewer 2.0 更新於 2019.1.18

我對OcrViewer進行了一些功能拓展與界面美化，除了標准的本地圖片識別功能，我增加了如下幾點新功能，幫助你更方便使用本工具，進而更好地識別圖像中的文字：

1. 全新的界面設計，將會帶來全新的使用體驗；
1. 在創作中心設置你喜愛的代碼高亮樣式，Markdown 將代碼片顯示選擇的高亮樣式 進行展示；
1. 增加了 截圖識別 功能，你可以通過截取圖片直接直接進行識別；
1. 增加了圖片預覽功能，更加方便進行圖文對比，減少容錯；
1. 增加了 清除圖片預覽 功能，可以清清除覽的圖片；
1. 增加了 重新識別 等功能，如果不確定可以多次識別提高識別精確率；

下面是功能以及新界面展示
