I've just started with Computer Vision and also with OpenCV.

I'm working with MRI brain images and I wondering if there is a filter or something that let me segment the areas that I haver marked with red on this image: image description

The original image is this one: image description

Yes, I know that there are a lot of deep learning solutions to segment this kind of networks, but I'm wondering, because I'm newbie, if there is a filter to highlight these areas that I have surrounded.

You could use image thresholding to highlight the brightest areas, to begin with. Then, some heuristics to determine an interior zone and/or any other relevant information (e.g., the pixels are near one of the black areas)
