    Comment on it

    OCR means Object Character Recognition . It is a technique by which we select a portion of the image as per user need.

    This process requires getting the dimension of selected screen and converting in an image for use.

    These are the pre-processing steps often performed in OCR :

      Binarization
    • Usually presented with a image, conversion is then simply a matter of choosing a maximum value.

      Morphological Operators
    • Remove empty things in characters, can use the majority operator.

      Segmentation
    • Check connectivity of shapes, label.

      private static void ReadTextFromImage(String ImagePath)  
            {  
                try  
                {  
                    // Grab Text From Image  
                    MODI.Document ModiObj = new MODI.Document();  
                    ModiObj.Create(ImagePath);  
                    ModiObj.OCR(MODI.MiLANGUAGES;ENGLISH, true, true);  
    
                    //Retrieve the text gathered from the image  
                    MODI.Image ModiImageObj = (MODI.Image)ModiObj.Images[0];  
    
    
                    System.Console.WriteLine(ModiImageObj.Layout.Text);  
    
                    ModiObj.Close();  
                }  
                catch (Exception ex)  
                {  
                    throw new Exception(ex.Message);  
                }  
            }
