If the image is greyscale and only has values of 0 or 'non-zero' then it is just trivially
binaryVals - logical( myImage );
If it is in true RGB and you still just want effectively black and 'non-black' (which in this case looks like it is all just white) then
binaryVals = logical( sum( myImage, 3 ) );
should work.
