files, 1:1 mapping on the faceMesh API to .obj, as well as initial research on Point Set Registration. I discussed with the GTA on why the Pint set registration did not work for us. Point set registration ended up being too complicated to implement as all the models we had were a 5:1 mapping minimum. So mapping these 5:1 vertices required (https://en.wikipedia.org/wiki/Point_set_registration#Coherent_point_drift) which I could not understand. And even after we got that implemented we would still need to use interpolation to move the rest of the points. After speaking with the GTA he gave us the idea of generating a 3D model in which we would have 1:1 mapping. >- Helped on research with Point Cloud Registration. (https://en.wikipedia.org/wiki/Point_set_registration) >- Reorganized the whole notebook from Jacobs start to be more readable and expandable. >- Created the faceMesh Object that we use in the "Mapping" and "Texture" options. >- Worked on researching a way to create .obj files by reverse engineering the professors obj2sc function >- Wrote the blender script that ultimately built our object that got exported to a .obj >- Helped organize and coordinate team with Jacob throughout the project. >- Assisted in editing every object we use in this project through blender. I scaled and exported all the morph heads. >- Assisted in creating the logic to hook up the faceMeshAPI to object points. >- Studied Blender and Blender scripts for project. `47:T52f,md`***Abdool Shakur*** > Member of the Tensflow API Team. >- Helped in software design by coming up with ideas for this project. These included vertex mapping and morphing using multiple models. >- Collaborated with the team to extract facial landmarks from the facemesh API for future use in the mapping. >- Reworked the notebook to allow readability and less code, which means less prone to errors. >- Created a slider to slown down rendering time and allow for freezing the facemesh API, which allowed me to extract the vertices, vertex textures, vertex normals, and faces from the facemesh API. This ended up being the key component in recreating the facemesh API into an obj file to allow 1:1 mapping for our final product. >- In addition, I also created secondary options for this project (in case the 1:1 mapping failed) by creating real time face tracking via morphing. Morphing means that, based upon what expression the user is doing on the webcam (such as opening their mouth), the rendered model on screen would quickly changed to a model with its mouth open to mimic the user. This was done seamlessly to create the effect of a model reacting in real time to the player. >- Helped in debugging and troubleshooting code. >- Implemented face landmark tracking algorithm to detect what expressions a user was
