+ | |||
+ | == How to set up == | ||
+ | |||
+ | The user have to include all the necessary libraries and the header files which were mentioned above, | ||
+ | to the working directory. | ||
+ | |||
+ | Then you can run the SahanaOCRUI exe or run the project using the Visual Studio. | ||
+ | |||
+ | == procedure == | ||
+ | |||
+ | Here is the link for a video guide | ||
+ | |||
+ | when you run the project you can see the initialize window of the project. | ||
+ | {{: | ||
+ | |||
+ | It contains select boxes for | ||
+ | |||
+ | * choosing the scanner | ||
+ | * choosing the images from the file system | ||
+ | * choosing the Xforms from the file system | ||
+ | |||
+ | So initially the user can select whether he is using the images from the file system or form the | ||
+ | feed the images by scanning from the scanners, by selecting the check box available in the initialize | ||
+ | form. Then if you select scanner you wanted to select the corresponding xform for it. For the scanner | ||
+ | there are two options to configure the scanner and to test the scanners. | ||
+ | |||
+ | By the configure option we can configure the scanner settings. | ||
+ | {{: | ||
+ | |||
+ | The Test option provide you a chance to check whether the scanner is correctly working with the application | ||
+ | and is it scanning correctly. | ||
+ | {{: | ||
+ | |||
+ | By the Test it scans the image and show it on the preview window as above. | ||
+ | |||
+ | |||
+ | Or else you can select the image and the corresponding Xform for it. Then after submitting those images the | ||
+ | system direct you to the main form of the application. | ||
+ | |||
+ | The process window is as follows. | ||
+ | {{: | ||
+ | |||
+ | If you are using the images from the file system, you can see the image you have submit to the system at the | ||
+ | main form. Or else there is a option to scan the images from the scanners. | ||
+ | |||
+ | After that you can start the process of form processing and the system directs you to the Log form which shows | ||
+ | process of the form. | ||
+ | {{: | ||
+ | |||
+ | At the Log window there is a image box that updates the segmented current letter box of the form. And there also | ||
+ | a text box that shows the corresponding recognized letter during the process. | ||
+ | |||
+ | There is a text area in the Log form that shows the results of the data fields during the process. | ||
+ | |||
+ | == Conclusion == | ||
+ | |||
+ | These are the basic functions of the SahanaOCR project. | ||
