how can I adjust the contrast of an image in cpselect window. My fixed image has a bad contrast compared to my moving image and I want to fix this. Can anyone help?

function [xymoving_out,xyfixed_out]=Two_D_Landmark_Reg_082715(fixed_image,moving_image) moving=moving_image; fixed=fixed_image; fixed=imcontrast(fixed); show_moving=imshow(moving,[]); get_property=get(show_moving,'CData'); conadj_moving=imadjust(get_property); close all [xymoving_out,xyfixed_out]=cpselect(conadj_moving,fixed,'wait',true); end I try to run this and I get the rolling error

Error using iptcheckhandle (line 54) Function IMCONTRAST expected its first input argument, H, to be a valid handle to a single graphics object.
