Is there any option in openCV to read FITS (Flexible Image Transport System) images? Such image format has many applications in astronomical image processing.

According to Wikipedia, "The FITS Support Office at NASA/GSFC maintains a list of libraries and platforms that currently support FITS."
Once you have a memory buffer with the image, cv:Mat will probably be able to handle it.

Many thanks. Indeed I can use the NASA FITS/IO libraries to handle FITS images. But my aim is to avoid using other libraries and just rely on OpenCV functionality.

OpenCV is not meant to support a large set of specialized image and data I/O formats. These usually have their own tools. However, once you have pixel buffers, OpenCV can take it from there.

You can map file into the memory by mmap (for example), and then construct cv::Mat object by data pointer. That's the most simple way, i think. In common, before that you should to parse your FITS header to know dimensions and other info to make cv::Mat.
