Prashant - eliminate how? Set any pixel value that is not 255 to be zero?

You can change a pixel value in an image to some other value, but you cannot eliminate the pixel because matrices must remain rectangular, not have ragged edges like if you eliminate the pixel and shift all other pixels in the line or column over.

Try
mask = J > 200; % Map of where the image is 201 or greater.
theSum = sum(J(mask))
