How to recognize handwritten character using fuzzy logic ?

I am on a project to design a system which will take handwritten character images as input, recognize them using fuzzy logic and give the output of recognition. I am stuck at the stage of feature extraction and character recognition. I am not being able to figure out what to do and how to do. Any type of corresponding lead or clue will be great for me. Thank You.

Hi -

I understand that you're interested in using handwritten character images as inputs to a fuzzy logic system for classification.

I don't know of any full workflow examples in this domain using handwriting, but there are a couple of published examples that may help in different parts of the workflow:

• https://www.mathworks.com/help/fuzzy/fuzzy-logic-image-processing.html (Edge detection)
• https://www.mathworks.com/help/fuzzy/fuzzy-c-means-clustering-for-iris-data.html (Fuzzy C-Means clustering for classification)
• https://www.mathworks.com/help/fuzzy/classify-pixels-using-fuzzy-systems.html (Classifying pixels based on color or texture)

In addition, if you're not restricted to using fuzzy logic to solve this problem, the free 2 hour 'Machine Learning Onramp' course walks through how to use machine learning to solve this exact problem in great detail. I'd highly recommend it. Here's a link to that:

https://www.mathworks.com/learn/tutorials/machine-learning-onramp.html

Even if you do decide to pursue a fuzzy logic approach, that onramp discusses many potential features to extract for character recognition that could be useful in a fuzzy c-means clustering approach.

Cheers,

Kyle

Search the Image Processing literature here Vision Bibliography. Good luck.

Thanks for the help. But my problem is I don't know how to move forward. Any help on that logical part ??

I don't know fuzzy concepts - never had the need/opportunity/occasion to learn them.
