I have images like the one shown above and I want to convert the image to a binary image where the black parts are white and the rest of the image is black. How would I approach solving this problem?

Rbin = YourImage <= 42;

I assure you that it does work, with the exception of TIFF images that use IEEE floating point representation (these exist but are rare)

Try this:
grayImage = 255 - grayImage; % Assuming your image is uint8. Use 65535 if it's uint16.
