圖片文字識別代碼

1. java 實現圖片的文字識別

摘要圖像識別是目前很熱門的研究領域，涉及的知識很廣，包括資訊理論、模式識別、模糊數學、圖像編碼、內容分類等等。本文僅對使用Java實現了一個簡單的圖像文本二值處理，關於識別並未實現。
步驟
建立文本字元模板二值矩陣
對測試字元進行二值矩陣化處理
代碼

2. 學一學！Python3一行代碼實現圖片文字識別的示例

自學Python3第5天，今天突發奇想，想用Python識別圖片里的文字。沒想到Python實現圖片文字識別這么簡單，只需要一行代碼就能搞定
?

from
PIL
import
Image
import
pytesseract
#上面都是導包，只需要下面這一行就能實現圖片文字識別
text
=
pytesseract.image_to_string(Image.
open
(denggao.jpeg),lang
=
chi_sim)
print
(text)

我們以識別詩詞扮輪爛為例
下面是我們要識別的圖片
先看下效果圖
我們運行代碼後識別的結果,有幾個字沒有正確識別，但是大多數字都能識別出來。

風急天高猿嘯哀 渚芸胄芳少白鳥飛鳳
無邊落木蕭蕭下, 不盡長量工盲袞宕袞來
萬里悲秋常1乍窨, 百年多病獨登氤
艱難苦恨擎霜量 漂倒新停澍酉帆

一行代碼就能識別圖片，我們背後要做些准備工作的
這里我們需要用到兩個庫：pytesseract和PIL
同時我們還需要安裝識別引擎tesseract-ocr
下面就來講講這幾個庫的安裝，因為只有這幾個庫安裝好以後Python才能實現桐扮一行代碼實現圖片文字識別
一，pytesseract和PIL的安裝
安裝這兩個包可以藉助pip
- 1，命令行安裝
?

2

pip install PIL
pip install pytesseract

- 2，如果你用的pycharm編輯器，就可以直接藉助pycharm實現快速安裝。
在pycharm的Settings設置頁按照下面步驟操作
這樣就能成功安裝pytesseract，安裝PIL只需要在上面第三步里搜索PIL並點擊安裝即廳漏可
這時我們安轉好了庫，運行下面代碼
