Answer 1

Try imfuse() or imshowpair().

thank you.I try this,HV=imfuse(H+V); but it gives the error message."??? Undefined function or method 'imfuse' for input arguments of type 'double'.".I cant understand that I'm very new for MATLAB.

[Image Analyst]

You used a + instead of a comma. Try imfuse(H,V). Plus you need to have a modern version of MATLAB. You probably should upgrade to R2013b, because you probably have an ancient version.

It depends a lot on your images and what you exactly want, but did you try to just sum them?

overlay_im=image1+image2;

If this is not what you need, please elaborate more on what you would like to achieve.

[mahesh chathuranga]

thank you.but this is not the result what i want. this is my problem, i have two images derived from one image. image1=vertical edges of the original image image2=horizontal edges of the original image now i want to overlay both without summing them

[Laurent]

Ah, assuming that your images are binary images you could do:

overlay_im=image1|image2;

Image Analyst's answer to use imfuse is good. To use imfuse, you have to have the Image Processing Toolbox with version R2012a or later.

Another option is imoverlay on the File Exchange.
