From Youtube to Blender: Forensic facial reconstruction of a child mummy

This post is about a practical application of a serie of studies published here in this blog.

After I started to study about forensic facial reconstruction I saw that is much more easy to find videos of CT-Scan than the DICOM files and other tomography formats.

A way to convert a video in a reconstructed mesh was described here.

Some days ago I was reading about mummies (desperate to find a CT-Scan) and I found this post:

It talks about a child mummy of St. Louis, that lived in a range of 40 BC and 130 AD. He died with 7 or 8 months.

Inside the matter had a video with some seconds of a CT-Scan slicing. I was able to convert it in a reconstructed mesh, and after I found a video on Youtbe with more qualty and I used it to make the final mesh, used in this post.

I downloaded the video with Videodownload Helper (Firefox) and it was converted in a image sequence and after in a serie of DICOM files.

Unfortunately I lost the original vetorial file and now we have only the infographic in Portuguese version, like you can see below (but it have a lot of images, that dispensing you to read it).

To make a reconstruction with historical and archaeological foundation I had the help of Moacir Elias Santos, archaeologist of the Egypt Museum and Rosacruz, from Brazil.

The animated gif above shows the extracted frames of the animation converted into a CT-Scan. I reduced the slices to make it more didatic.

I had a serie of dificulties to find landmarks to use on the child's face, cause appear that it doesn't exist. So I use a average of 3-8 year and rescale it to have at least a reference.

I use a serie of babies pictures to draw the line of the neck and ears.

Moacir sent me a compose image with the original mummy, that you can see below.

I hope you enjoy this post. I see you in the next. A big hug!
