資源簡介

基于文檔圖像的文字識別系統包括兩個處理步驟。第一步為文字分割，即確定圖像中文字序列的區域，并將邏輯相關的多個字符分割開來。第二步是字符識別，即是利用文字分割的結果，基于字符的圖像及上下文信息，生成該字符相應的數字化表現形式，以便后期處理，如顯示、翻譯等。 由此可見，文字分割是OCR（光學字符識別）系統中的關鍵技術，正確的文字分割是文字識別成功的前提。目前的OCR系統大多是針對文字排列整齊，前景色與背景色對比明顯的理想文檔圖像而設計，這雖然適用于很多印刷文檔的情形，但對于文字排列的方向和大小都很隨意的手寫體文檔、圖書封面等復雜文檔圖像卻無法提供可靠的文字分割結果，以下列出幾種常見比較常見的文檔圖像。 本文所介紹的方法，即復雜背景下的文字分割方法，希望利用字符的輪廓信息，通過逐步探測的方法完成對復雜文檔圖像的文字分割，經實驗證明，該方法可以有較地解決文字排列不規則、同組文字大小不等、背景色復雜的文字分割問題。
