Dosya Ayrıntıları

Image Noise Reduction Filter

A new preprocessing filter has been added to the OCR API that automatically removes various types of image noise; such as, unwanted gradients, glare, scratches, dirty spots, dirt, etc.

The following C# code snippet shows the Auto Denoising method of API in action:

using Aspose.OCR;

namespace ProgramOCR
{
    class Program
    {
        static void Main(string[] args)
        {
            // Create instance of OCR API
            AsposeOcr api = new AsposeOcr();
            // Add denoise preprocessing filter
            PreprocessingFilter filters = new PreprocessingFilter {
            	PreprocessingFilter.AutoDenoising()
            };
            // Preprocess an image
            MemoryStream ms = api.PreprocessImage("image.jpg", filters)
            // Save cleaned image into a file
            using(FileStream file = new FileStream("result.png", FileMode.Create, System.IO.FileAccess.Write))
            {
            	ms.WriteTo(file);
            }
        }
    }
}

Image Skew Correction Filter

Introduced the filter that corrects the image skew by straightening (deskew) the skewed images.

The following C# code sample demonstrates how you may increase the image recognition accuracy of photos taken from smartphone or inaccurate scans by using AutoSkew() method in API:

using Aspose.OCR;

namespace ProgramOCR
{
    class Program
    {
        static void Main(string[] args)
        {
            // Create instance of OCR API
            AsposeOcr api = new AsposeOcr();
            // Add deskew preprocessing filter
            PreprocessingFilter filters = new PreprocessingFilter {
            	PreprocessingFilter.AutoSkew()
            };
            // Preprocess an image
            MemoryStream ms = api.PreprocessImage("image.jpg", filters)
            // Save straightened image into a file
            using(FileStream file = new FileStream("result.png", FileMode.Create, System.IO.FileAccess.Write))
            {
            	ms.WriteTo(file);
            }
        }
    }
}
