Re: Extracting RAW image from JPG

Just to add another tool to the mix - my team just released a Python library which lets you load up the RAW data from a raspistill RAW+jpeg file into a Python numpy array for easy analysis. We have been using a fork of dcraw but we wanted to skip the .dng file step and pull the data straight into Py...

Re: Raw Image & pixel-by-pixel RGB information

My team has been working on a similar problem (analyzing raw data from the pi camera) We ended up forking the picamera library so that we could pull the RAW data out of the RAW + JPEG files and process that. If you're familiar with the Python numpy/scipy stack, this'll be the best way to go: Simply ...

Re: RAW output information

what's the quickest way to extract the RAW information from the jpeg image into a numpy array?
My team just released a fork of picamera that is designed just for this. Check out https://github.com/OsmoSystems/picamraw/ and let us know how it goes!

Re: Pi Camera V2 raw bayer data

This is a pretty old thread, but I thought folks reading it might be interested to know - in Python, my team just released a fork of picamera which pulls out the raw data from a raw+jpeg file into a more consumable, numpy format. It includes only the most basic demosaicing. Check out https://github....
