使用有损技术的Dicom图像压缩

问题描述

任何人都可以帮我压缩DICOM（.dcm）图像文件。

我能够通过使用GZipStrim一类使用System.IO.Compression命名空间来实现它50％压缩，我想要高达80％的压缩。有可能通过使用有损压缩，但我不知道该怎么做？



请帮帮我，我怎样才能实现它？？



我是什么尝试过：



string [] sFiles = Directory.GetFiles（sInDir，* .DCM *，SearchOption.AllDirectories）;

int iDirLen = sInDir [sInDir.Length - 1] == Path.DirectorySeparatorChar？ sInDir.Length：sInDir.Length + 1;



using（FileStream outFile = new FileStream（sOutFile，FileMode.Create，FileAccess.Write，FileShare.ReadWrite））

使用（GZipStream str = new GZipStream（outFile，CompressionLevel.Optimal，true））





foreach（ sFiles中的字符串sFilePath）

{

string sRelativePath = sFilePath.Substring（iDirLen）;

if（progress！= null）

进度（sRelativePath）;

CompressFile（sInDir，sRelativePath，str）;

}



它给了我50％的压缩但是想压缩uoto 80％。

Can any one please help me in compression of DICOM(.dcm) image file.
I am able to do it by using GZipStrim a class of using System.IO.Compression namespace which gives upto 50% compression and i want upto 80% compression. It may be possible by using lossy compression but i don't know how to do it?

please help me out how can i achieve it...?

What I have tried:

string[] sFiles = Directory.GetFiles(sInDir, "*.DCM*", SearchOption.AllDirectories);
int iDirLen = sInDir[sInDir.Length - 1] == Path.DirectorySeparatorChar ? sInDir.Length : sInDir.Length + 1;

using (FileStream outFile = new FileStream(sOutFile, FileMode.Create, FileAccess.Write, FileShare.ReadWrite))
using (GZipStream str = new GZipStream(outFile, CompressionLevel.Optimal,true))


foreach (string sFilePath in sFiles)
{
string sRelativePath = sFilePath.Substring(iDirLen);
if (progress != null)
progress(sRelativePath);
CompressFile(sInDir, sRelativePath, str);
}

it is giving me 50% compression but wants to compress uoto 80%.
