thanks for your attention for example i have 9 frames of echocardiography in 9 time indexes, and i want to have 18 frames instead, so i have to produce one frame between each two consecutive frames to make the number of frames double

hi Tala, I am working on the same problem. Did you check the possibilities of imwrap() can you share your experience?

Like Adam says, you can just take the average of the two. This will average intensities but it does not move structures laterally/spatially like a morphing/warping would. To do that you'd need to identify landmarks in the initial and final image and then use imwarp() or something to warp the image.
