Give an example. You almost never want to do an operation on a figure (the gray background with axes, an image, tick marks, annotations, etc.). You almost always want to do operations directly on the image itself.

If you really want to save a figure window as an image and read it back in with imread, then use export_fig(), followed by imread(). http://matlab.wikia.com/wiki/FAQ#How_do_I_save_my_figure.2C_axes.2C_or_image.3F_I.27m_having_trouble_with_the_built_in_MATLAB_functions.
