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.

how to get binaryVals sir ? this is binary image. and the meaning of the question is how to convert or how to show from this image :

to be this image :

?

thanks for your answer sir....

I don't understand what you mean by the 'image' below. You can see the binary values in the variable editor, but you can't plot them in an image as visible 1s and 0s like that. The image on top is a usual representation of a binary image and the code I gave you should give you the values that make up that image.

thank u for your answer, this image is braille text, i want to translate braille text to alphabet, so i have to get feature extraction for classification.
