2.  To convert alpha-numeric character from image into normal text form.  To get general idea on image processing.

4.  Taking image as input.  Converts into normal text form.  Recognizes alpha-numeric characters only.  Edit and Save recognized text. Loaded Image Converted Text Editable

5. Save Text Matrix Matching Feature Extraction Character Segment Line Segment Thinning Binarization Get Image Bold Thin

6.  Otsu Binarization Algorithm  Hilditch Skeletonization Algorithm (Thinning)

7.  Generic Segmentation

8.  Feature Extraction (zonning) Based on Zones 5 horizontal and 5 vertical zones =>25 features Based on Upper and Lower profiles 10 vertical zones => 20 features Based on Left and Right profiles 10 horizontal zones => 20 features Total Number of features 25 + 20 + 20 = 65

9. OFF DAYS: Exam Time: (25 Days) Dashain Holidays: (15 Days) Tihar Holidays: (3 Days)

10. Choosing the correct algorithm. Hard to implement algorithm. Implemented, but output is not accurate. accuracy of matrix matching.

11.  Text from image gets converted to text file.  Simplest algorithm; accuracy is about 40%-60%.

12.  Can’t recognize text in noisy image.  Can’t detect inclined text from image.  Matrix matching is slow.  Bad thinning & noise makes some text unrecognizable.

13.  Scanner image input.  Recognize PDF and other image format.  Nepali / Devnagari font support.  Different fonts.  Output in PDF or Word file format.  Skewing & Noise reduction.  Handwritings.  Neural Network.
