Python中的RAW图像处理 [英] RAW Image processing in Python

问题描述

是否有任何Pythonic解决方案来读取和处理RAW图像。即使它只是访问原始照片文件（例如cr2或dng），然后将其输出为jpeg。

Are there any Pythonic solutions to reading and processing RAW images. Even if it's simply accessing a raw photo file (eg. cr2 or dng) and then outputting it as a jpeg.

理想情况下是python的dcraw绑定，但其他任何可以完成它的东西也足够了。

Ideally a dcraw bindings for python, but anything else that can accomplish the came would be sufficient as well.

推荐答案

前一段时间我写了一篇名为 rawpy 。这很容易使用：

A while ago I wrote a libraw/dcraw wrapper called rawpy. It is quite easy to use:

import rawpy
import imageio

raw = rawpy.imread('image.nef')
rgb = raw.postprocess()
imageio.imsave('default.tiff', rgb)

它本身适用于numpy数组并支持许多选项，包括直接访问未处理的Bayer数据。

It works natively with numpy arrays and supports a lot of options, including direct access to the unprocessed Bayer data.

这篇关于Python中的RAW图像处理的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
