tesseract ocr engine

OCR belongs to the category of CV, that is, computer vision. Currently, apart from the leading boss of opencv, tesseract developed by HP, it is relatively easy to use, although it has been a long time, but now it is maintained by Google and hosted on Google Code. Now the Android version is availableAddress: http://code.google.com/p/tesseract-android-tools/ This

Then the previous OCR said. The previous article introduced the simple use of tesseract in the command line, of course, to inherit into our program, or need code implementation. Here's a sample of the Java implementation that you'll share.watermark/2/text/ahr0cdovl2jsb2cuy3nkbi5uzxqvbg1qnjiznty1nzkx/font/5a6l5l2t/fontsize/400/fill/i0jbqkfcma==/ Dissolve/70/gravity/center "/>Take the code to scan the image a

Here I recognize pure letters, so I use the English Language Pack. In addition, in order to improve the verification rate, you can also perform traini

The Chinese New Year is approaching, and the new application of the blogger-screen word-taking-the-old image coding work is also in full swing.
