Question

DIGITAL IMAGE PROCESSING (Matlab)

Q) Design in such a way that if a picture of specific visiting card is already saved in the device (laptop) and your job is to extract the data from it:

1)name

2)Address

3)Number

After extracting the specific data, save it in a text boxes or in a text file provided below.

NOTE : the following code is to be done on Matlab using DIP techniques, Thank You.

Answer 1

syntax

txt = ocr(I)

txt = ocr(I, roi)

[___] = ocr(___,Name,Value)

recognising the image

businessCard   = imread('businessCard.png');
     ocrResults     = ocr(businessCard)

ocrResults = 
  ocrText with properties:

                      Text: '‘ MathWorks®...'
    CharacterBoundingBoxes: [103x4 double]
      CharacterConfidences: [103x1 single]
                     Words: {16x1 cell}
         WordBoundingBoxes: [16x4 double]
           WordConfidences: [16x1 single]

     recognizedText = ocrResults.Text;    
     figure;
     imshow(businessCard);
     text(600, 150, recognizedText, 'BackgroundColor', [1 1 1]);

ocrResults = 
  ocrText with properties:

                      Text: '‘ MathWorks®...'
    CharacterBoundingBoxes: [103x4 double]
      CharacterConfidences: [103x1 single]
                     Words: {16x1 cell}
         WordBoundingBoxes: [16x4 double]
           WordConfidences: [16x1 single]

     recognizedText = ocrResults.Text;    
     figure;
     imshow(businessCard);
     text(600, 150, recognizedText, 'BackgroundColor', [1 1 1]);

roi = [360 118 384 560];

ocrResults = ocr(I, roi);

Iocr = insertText(I,roi(1:2),ocrResults.Text,'AnchorPoint',...
    'RightTop','FontSize',16);
figure; imshow(Iocr);

 businessCard = imread('businessCard.png');
     ocrResults   = ocr(businessCard)

ocrResults = 
  ocrText with properties:

                      Text: '‘ MathWorks®...'
    CharacterBoundingBoxes: [103x4 double]
      CharacterConfidences: [103x1 single]
                     Words: {16x1 cell}
         WordBoundingBoxes: [16x4 double]
           WordConfidences: [16x1 single]

     Iocr         = insertObjectAnnotation(businessCard, 'rectangle', ...
                           ocrResults.WordBoundingBoxes, ...
                           ocrResults.WordConfidences);
     figure; imshow(Iocr);

finding hilght in busines card

businessCard = imread('businessCard.png');
ocrResults = ocr(businessCard);
bboxes = locateText(ocrResults, 'MathWorks', 'IgnoreCase', true);
Iocr = insertShape(businessCard, 'FilledRectangle', bboxes);
figure; imshow(Iocr);
