[SerializableAttribute()]
public struct OcrStatistic
@interface LTOcrStatistic : NSObject public class OcrStatistic [SerializableAttribute()]
public value class OcrStatistic : public System.ValueType
Example
This example will show the statistics of the last recognition operation on a page.
using Leadtools;
using Leadtools.Codecs;
using Leadtools.Ocr;
using Leadtools.Document.Writer;
public void OcrStatisticExample()
{
// Create an instance of the engine
using (IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD))
{
// Start the engine using default parameters
ocrEngine.Startup(null, null, null, LEAD_VARS.OcrLEADRuntimeDir);
string tifFileName = Path.Combine(LEAD_VARS.ImagesDir, "Ocr1.tif");
string pdfFileName = Path.Combine(LEAD_VARS.ImagesDir, "Ocr1.pdf");
// Create an OCR page
using (IOcrPage ocrPage = ocrEngine.CreatePage(ocrEngine.RasterCodecsInstance.Load(tifFileName, 1), OcrImageSharingMode.AutoDispose))
{
// Process the page
ocrPage.AutoPreprocess(OcrAutoPreprocessPageCommand.Deskew, null);
// Recognize the page
// Note, Recognize can be called without calling AutoZone or manually adding zones. The engine will
// check and automatically auto-zones the page
ocrPage.Recognize(null);
// Show the statistic about the last recognize operation
OcrStatistic statistic = ocrEngine.GetLastStatistic();
Console.WriteLine("Recognized characters: {0}", statistic.RecognizedCharacters);
Console.WriteLine("Recognized words: {0}", statistic.RecognizedWords);
Console.WriteLine("Rejected characters: {0}", statistic.RejectedCharacters);
Console.WriteLine("Corrected words: {0}", statistic.CorrectedWords);
Console.WriteLine("Recognition time: {0} ms", statistic.RecognitionTime);
Console.WriteLine("Reading time: {0} ms", statistic.ReadingTime);
Console.WriteLine("Image Preprocessing time: {0} ms", statistic.ImagePreprocessingTime);
Console.WriteLine("Decomposition time: {0} ms", statistic.DecompositionTime);
Console.WriteLine("Post processing time: {0} ms", statistic.ReadingTime - statistic.RecognitionTime);
}
// Shutdown the engine
// Note: calling Dispose will also automatically shutdown the engine if it has been started
ocrEngine.Shutdown();
