fo-dicom.Codecs

This is collaborative project mantained by Fellow Oak Dicom and Efferent Health, LLC. The codecs in this repository are written in pure C/C++ code and wrapped with C# and netstandard2.0. The supported platforms so far are:

• Windows 64-bit (tested with Windows 10)
• Linux 64-bit (tested with Ubuntu 16/18 Desktop and Server)
• MacOS (tested with macOS High Sierra Version 10.13)

Supported CODECs

The following CODECS are implemented:

• JPEG 2000 Image Compression (Lossless Only)
• JPEG 2000 Image Compression
• JPEG Baseline (Process 1): Default Transfer Syntax for Lossy JPEG 8 Bit Image Compression
• JPEG Extended (Process 2 & 4): Default Transfer Syntax for Lossy JPEG 12 Bit Image Compression - (Process 4 only)
• JPEG Lossless, Non-Hierarchical (Process 14)
• JPEG Lossless, Non-Hierarchical, First-Order Prediction (Process 14 [Selection Value 1]): Default Transfer Syntax for Lossless JPEG Image Compression
• JPEG-LS Lossless Image Compression
• JPEG-LS Lossy (Near-Lossless) Image Compression
• RLE Lossless

Usage

• Add the nuget package to your .net Standard or .net Core project
• Add the standard fo-dicom nuget packages to your project (tested with 4.0.5)

With fo-dicom 4.0

• Add the nuget package to your .net Standard or .net Core project (minimum version is 2.0)
• Add the standard fo-dicom nuget packages to your project (version 4.0.x)
• At the beginning of your application, replace the transcoder manager, as:

  Dicom.Imaging.Codec.TranscoderManager.SetImplementation(new Dicom.Imaging.NativeCodec.NativeTranscoderManager());

With fo-dicom 5.0

Version 5.0 will incorporate these codecs by default

Discussion topics

• Evaluate the coupling of fo-dicom with fo-dicom.Codecs (both directions)
• Determine if the same source code can be used for regular .net Framework
• Roadmap for increasing the platform coverage: iOS, Android, etc.
• Better testing strategy (consider codecs, color resolution, color encoding, LUT, palette, etc.)
• Add parallel processing capability
