I am currently implementing 3d face reconstruction from a single image using a single reference face shape by ira kemelmacher-shlizerman, ronen basri.
It uses shape from shading but with help of reference model in reconstruction of surface. I am currently working depth recovery step. Recovery is done by help of three parameters
z_ref - depth of reference model zref(x,y)
p_ref - albedo of reference model pref(x,y)
n_ref - normals of reference model nref(x,y)
i am using matlab mesh toolkit. Which helps in calculation of surface normals through compute_normal(vertex, face). Which returns normal for each vertex of mesh (face-vertex mesh). I have input images of size 640x480 so maximum x is 640 and maximum y is 480 for all functions. But the surface normals are in form of 3xnumberofvertices matrix. I am unable to map it with other functions i have in prior steps for example z(x,y) - z_ref(x,y) in equation 6, how such type of representation mappings can be made?
Secondly, i need depth map of face-vertex mesh in form z(x,y) [parametric surface] for mentioned size of images?
Any help is appreciated
thanks in advance.+2 Other Responses
3d Animation & Modeling
Looking for an experienced freelancer with 3d animation, 3d modeling, motion graphics and video editing skills. Each video is about 5 minutes long or less with a combination of: 3d animated scene, pre-recorded clips of someone talking on camera and graphic text, charts, diagram & picture scenes.
Here are some examples of the videos:
example 1 - https://www.Youtube.Com/watch?V=pjqmzkiyl6o
example 2 - https://www.Youtube.Com/watch?V=t5qhxvn2meo
the 3d model of the animated character, environments and graphics have already been created and will be given to you. It just need some rigging and to be moved around based on the script.
For each video, you will be given a detailed script with each scene break down
all voice overs, recorded video clips and pictures will be provided
the videos are pretty consistent. We will start with one video a month. After you become more familiar with the video style and brand we can move up to 3 or 4 a month.
* must have prior work examples of 3d animated videos and 3d modeling.
Please respond with a short summary of your qualifications and some examples of your work.+17 Other Responses
