CreateSession

ImageMasking.CreateSession method

创建可以执行再训练分解操作的屏蔽会话。

public IMaskingSession CreateSession(MaskingOptions options)
范围类型描述
optionsMaskingOptions选项。

返回值

可以执行再训练分解操作的屏蔽会话。

例子

将屏蔽会话保存到文件以用于长时间会话，以及在另一个环境中恢复会话的可能性。

[C#]

string dir = "c:\\temp\\";
string sessionBackupFile = dir + "session.bak";

// 屏蔽导出选项
Aspose.Imaging.ImageOptions.PngOptions exportOptions = new Aspose.Imaging.ImageOptions.PngOptions();
exportOptions.ColorType = Aspose.Imaging.FileFormats.Png.PngColorType.TruecolorWithAlpha;
exportOptions.Source = new Aspose.Imaging.Sources.StreamSource(new System.IO.MemoryStream());

Aspose.Imaging.Masking.Options.MaskingOptions maskingOptions = new Aspose.Imaging.Masking.Options.MaskingOptions();
    
// 使用 GraphCut 聚类。
maskingOptions.Method = Masking.Options.SegmentationMethod.GraphCut;
maskingOptions.Decompose = false;
maskingOptions.Args = new Aspose.Imaging.Masking.Options.AutoMaskingArgs();

// 背景颜色为橙色。
maskingOptions.BackgroundReplacementColor = Aspose.Imaging.Color.Orange;
maskingOptions.ExportOptions = exportOptions;

// 首次启动会话并保存到文件
using (Aspose.Imaging.RasterImage image = (Aspose.Imaging.RasterImage)Aspose.Imaging.Image.Load(dir + "Gorilla.bmp"))
{
    // 创建 ImageMasking 类的实例。

    }

// 从文件恢复屏蔽会话

                                     };
        using (Aspose.Imaging.Masking.Result.MaskingResult maskingResult = session.ImproveDecomposition(args))
        {
            // 导出选项的显式传输，因为它不可序列化
            maskingResult.MaskingOptions.ExportOptions = exportOptions;

            using (Aspose.Imaging.RasterImage segmentImage = maskingResult[1].GetImage())
            {
                segmentImage.Save(dir + "step2.png");
