% Compute mean in 4-by-4 blocks
kernel = ones(4);
meanImage = conv2(double(grayImage), kernel, 'same') / numel(kernel);
% Compare actual image to mean image.
bitImage = grayImage >= meanImage;
From the bitImage is it possible to get back grayImage

No. There is no way to obtain the original gray level image from a binary image that has been created by thresholding that gray scale image. If you want the gray scale image later, be sure to save your gray scale image variable.
