Coursework: Image Preparation for Optical Character Recognition
Coursework Problem
Optical character recognition (OCR) is the process is the process of translating an image (or video) of text into machine encoded text. OCR algorithms typically work well when applied to clear images in which contain only text, but can struggle where the image contains elements other than text or when the image is noisy. As such, image processing techniques can be applied to images in order to better prepare them for OCR. In this assignment, you will design and investigate the performance of an algroithm for preparing images for OCR. You will apply this algorithm in an application context of your choice. You will be required to:
• Conduct personal research to choose a potentially suitable algorithm for document image preparation.
• Implement your chosen algorithm in Matlab and apply it to a set of test images.
• Analyse the results (either subjectively or objectively) of applying your chosen algorithm and draw conclusions from them.
While it is expected that your algorithm will improve the performance of OCR in comparison to applying OCR to unprepared images, it is not expected that your algorithm will allow OCR to perfectly recognise all characters in all test images.
You will report on this work in the style of an academic paper, making clear your experimental methodology and your results and conclusions.
Test Images
For this coursework, you should select an application of OCR to work on. In order to demonstrate your algorithm's performance of your algorithm, you will need a representative test set of images on which to employ it. You can choose your application freely but, to give you a start, you might want to look at the following applications and images:
- License plate recognition: The "Cars 1999 (Rear) 2" dataset from Caltech (www.vision.caltech.edu/html-files/archive.html) would be a good source of test images.
- Document recognition: The DIBCO 2011 benchmark data set (https://utopia.duth.gr/~ipratika/DIBCO2011/benchmark/dataset/) is a good source of document images.
