在二进制图像中仅显示8个连接的blob

Question

我在Aforge中使用blobcounter类通过给出最小高度和最小宽度的blob来提取blob。现在我想要显示一个二进制图像，其上只绘制了8个连接的blob（在黑色背景上只绘制了白色的好blob）。我该怎么做呢

  BlobCounter blobCounter = new BlobCounter(); 
blobCounter.FilterBlobs = true;
 blobCounter.MinWidth = minWidth; 
blobCounter.MinHeight = minHeight; 
blobCounter.MaxWidth = maxWidth;
 blobCounter.MaxHeight = maxHeight; 
blobCounter.CoupledSizeFiltering = true; 
blobCounter.ProcessImage(image); 
Blob[] blobs = blobCounter.GetObjectsInformation();
