How do I perform Optical Character Recognition (OCR) using MATLAB?

Use the ocr function from the Computer Vision Toolbox™ to perform Optical Character Recognition. Classify digits using HOG features and a multiclass SVM classifier. Run the command by entering it in the MATLAB Command Window.

How can I improve the accuracy of my text recognition?

Using deducible knowledge about the characters in the input image helps to improve text recognition accuracy. For example, if you set CharacterSet to all numeric digits, ‘0123456789’, the function attempts to match each character to only digits. In this case, a non-digit character can incorrectly get recognized as a digit.

How do I classify digits using MATLAB?

Classify digits using HOG features and a multiclass SVM classifier. Run the command by entering it in the MATLAB Command Window. Web browsers do not support MATLAB commands. Choose a web site to get translated content where available and see local events and offers. Based on your location, we recommend that you select: United States.

Can I use the OCR to generate traineddata in Hindi?

If you want to use Hindi, the English traineddata file must also exist in the same folder as the Hindi traineddata file. The ocr only supports traineddata files created using tesseract-ocr 3.02 or using the OCR Trainer. For deployment targets generated by MATLAB® Coder™ : Generated ocr executable and language data file folder must be colocated.

How do you add a title to a graph in MATLAB?

Adding Title, Labels, Grid Lines and Scaling on the Graph. MATLAB allows you to add title, labels along the x-axis and y-axis, grid lines and also to adjust the axes to spruce up the graph. The xlabel and ylabel commands generate labels along x-axis and y-axis. The title command allows you to put a title on the graph.

How to draw a smoother graph using MATLAB?

MATLAB draws a smoother graph −. MATLAB allows you to add title, labels along the x-axis and y-axis, grid lines and also to adjust the axes to spruce up the graph. The xlabel and ylabel commands generate labels along x-axis and y-axis. The title command allows you to put a title on the graph.

How to plot the graph of a function in MATLAB?

MATLAB – Plotting. To plot the graph of a function, you need to take the following steps −. Define x, by specifying the range of values for the variable x, for which the function is to be plotted. Following example would demonstrate the concept.
