Hi akmal,
I understand that you want to open image ".ict" and ".hct" files in MATLAB.
I recommend you use external tools or libraries to convert “.ict” and “.hct” image formats into a supported image format of MATLAB before opening them.
For more information regarding supported standard image formats of MATLAB, kindly refer to the following documentation:

I hope this answer helps you.
