Wavelet based volumetric medical image compression

作者:

Highlights:

• We investigated how to optimally compress volumetric medical images with JP3D.

• We extend JP3D with directional wavelets and intra-band prediction.

• Volumetric wavelets and entropy-coding improve the compression performance.

• Compression gains for medical images with directional wavelets are often minimal.

• We recommend further adoption of JP3D for volumetric medical image compression.
