问题描述

DICOM规范中,1.2.840.10008.1.2.4.70定义了一种传输语法为JPEG Lossless, Nonhierarchical, First- Order Prediction (Processes 14 [Selection Value 1]).

In the DICOM spec one of the Transfer Syntaxes is 1.2.840.10008.1.2.4.70 defined as JPEG Lossless, Nonhierarchical, First- Order Prediction (Processes 14 [Selection Value 1]).

"JPEG无损,非分级,一阶预测(过程14 [选择值1])"是什么意思?这种格式与JPEG-LS相同吗? 此页面似乎表明存在一些差异(JPEG-LS列在底部).

What does "JPEG Lossless, Nonhierarchical, First- Order Prediction (Processes 14 [Selection Value 1])" mean? Is this format the same as JPEG-LS? This page seems to indicate that there is some difference (JPEG-LS is listed in the bottom section).

是否可以在Python中读取或写入此格式?查看枕头的文档尚不清楚我认为该格式受支持.

Is is possible to read or write this format in Python? Looking over the docs for Pillow is no clear to me that the format is supported.

这篇文章有些相关.

推荐答案

JPEG无损一阶

Identical to the main JPEG lossless, but with a constrained value for the
predictor, giving a slightly simplified algorithm, with slightly greater
speed, but slightly less compression on most images (2-5% typically)
(from medicalconnections wiki)

您可以看看GDCM对jpeg压缩的dicom图像进行编码. GDCM Wiki链接
