Imagemagick is an image to image processor, not an image to text character processor. Therefore, Imagemagick does not have any function that will recognize text characters within an image. All it can do is automatically trim the image to the bounding rectangle about the text and output that image.

convert inputimage -fuzz XX% -trim +repage outputimage

where XX is some percent dissimilarity to the color in the corners of the image, so that if the background is not a pure color it can still get to the bounding rectangle.

If I misunderstand your problem/question, then please clarify.

Your question is about optical character recognition
which is not an ImageMagick function.
There's lots of info about Captcha and captcha solvers at

convert inputimage -fuzz XX% -fill white -opaque white -fill black +opaque white resultimage

where XX% is some percent different from white to allow for colors around the border of the letters to not be exactly the same as the letters due to antialising.
