Movie poster fun

One time our lab had a Christmas Party with Epic Movies as the theme. So each subgroup had to come dressed as characters from that movie. My group had the great fortune of being "cast" in The Lord of the Rings. I decided me and my students will go all out. So besides making props like swords and axes and beard, we even made... Tadah!.. a theatrical teaser poster with our faces superimposed on the characters.

We took pictures of our faces posed in the same way as the characters. Then with the help of GIMP and the use of ratio and proportion to get the scale of the faces right, we made this:

and this:

Making it was so much fun, my students were all game.

Then I thought, what if I share the fun with my  AP 186 class (Image Processing), besides there's a nice image scaling lesson there. And so for three years running, the first activity of my students in AP 186 is to recreate a movie poster with their faces in place of the actors'.

And so this year, I present to you the promotional posters of AP 186 2016!!!

The steps in making your own poster are:

1. Take a picture of yourself posed in the same way as the character. Be sure to get the lighting right too.

2. Crop your face using GIMP or any image processing software of your choice.

3. In the poster and and in your cropped image, measure the pixel distance between two fiducial points, e.g. distance between the eyes, distance from ear to ear, or forehead to jaw. 

4. Take the ratio between  the fiducial distance of the poster  and your image. Use this ratio as the scale factor to reduce or enlarge the size of your face image to fit exactly in the poster face.

5. You can also use the ratios of your skin color and the poster skin color to make the skin tone of your face match that of the poster.

6. You can then feather or smoothen the edges so that your cut out face blends with the rest of the poster image.

Practice makes perfect, soon you'll be posting memes in 9gag! Which poster got your thumbs up?
