Hi! I have an image in raw format (.raw) and I want to use it in Opencv (for several transformations). Is there any way to open and read it, or maybe to convert it into an appropiate format (jpg, bmp)? Thanks in advance!!

There's a library that I think can be used alongside OpenCV to manage raw images, it's called LibRAW

I never used it but a friend of mine told me that.

Also, here in this forum there is an example regarding RAW images handling in OpenCV: http://answers.opencv.org/question/58...

no, unfortunately there isn't.

there is even no clear definition, what raw means here, it can be anything from plain pixels (in which format ?) to something nested with proprietary headers, -- you're all on your own here.

try to look up the specs / documentation of the device, you get it from, then use native c++ methods (ifstream, etc) to slurp in the data. once you have it in memory, you can construct a cv::Mat like:

Mat m(height, width, type, pixelPointer);
