clj-ocr

A Clojure wrapper for Tesseract OCR

Installation

Add the following dependency to your project.clj file:

[org.clojars.scottxtra/clj-ocr "0.1.0-SNAPSHOT"]

Usage

Before using you must download train data for the language that you would like to preform OCR on. A function has been included to simplify this. In the clj-ocr.utils namespace, simply call:

(get-lang-data "<ISO 639-3 standard language code>")

Example for English:

(get-lang-data "eng")

Example for German:

(get-lang-data "deu")

Codes can be looked up here not every language code will work. It pulls from here.

To run OCR on an image, in clj-ocr.core simply call:

(do-ocr 
    (ImageIO/read (clojure.java.io/file "<filename>")) 
    (set-language "eng"))

Example:

(do-ocr 
    (ImageIO/read (clojure.java.io/file "pic.png")) 
    (set-language "eng"))

Implementation

This project is not meant to wrap the entire Tess4j wapper. It is meant to simplify the use of the most commonly used parts of Tesseract OCR.

Currently Implemented:
