Despeckle Library (royalties free)
buy on-line Image Processor download demo download evaluation version info
This despeckle sdk (API) allows the removal of speckle in scanned or faxed images. The speckle is the presence of black points of noise in images acquired by a scanner or received by fax.
Cleaning images is a very important preprocessing step to improve the compression rate, the visualization aspect and the accuracy using ICR/OCR.
Despeckle (speckle detection and deletion) can be very easily
performed, specifying the maximum width and height of isolated black elements to be considered as speckle.
You have obviuosly to supply a monochrome DIB (Device Indipendent Bitmap) in input to the process.
The despeckle process is fast and accurate.
For testing this library you can download a demo application (400 Kb) that allows you to use this function with your TIF images: please give us your feedback and your comments after the test !
In the last version of the library there's a new option, that allows you to perform smart despeckle: textual points (.,;:' ") won't be removed
even if their size is smaller than noise size!
Here you can see the source code in Microsoft Visual C++ of a sample application using the despeckle library:
int APIENTRY WinMain(HINSTANCE hInstance,
// Load dynamically the library
// Init the session
int Session= DESPECKLE_Init("demo", "demo");
// Check if a DIB is available in clipboard
bool bAvail= IsClipboardFormatAvailable(CF_DIB);
hBitmap = 0;
// Open the Clipboard
// Retrieve the DIB from clipboard
hBitmap = (long) GetClipboardData(CF_DIB);
// Find and removes points of speckle
long RemovedPoints= DESPECKLE_RemovePoints(Session, (long) hBitmap, 4, 4);
// Set the cleaned DIB to clipboard
// Close the Clipboard
// Format the output message
sprintf( buffer, "Removed %d points !
You can paste in your application...", RemovedPoints);
sprintf( buffer, "Image don't need to be cleaned !");
// Show the result
MessageBox(NULL, buffer, "RESULT", MB_OK);
// Show an error message
else MessageBox(NULL, "Unable to paste DIB", "ERROR", MB_OK);
// Close the session
// Unload the library
