Pixel-aligned Implicit Function (PIFu) uses deep learning models to turn 2D images of human beings into 3D meshes. The output can have a multitude of applications like game character creation, animated movie creation and entertainment. This study aims to explore possibilities of utilising the output from the PIFu model and reuse into creative applications.
We want the candidate to explore a specific area around 3D Human Digitization: the starting point for the project is this. It is essential to tune the algorithm to get an output that can be directly used in context without further adaptations.
The following minimum deliverables are expected from student undertaking the project:
- The candidate would be expected to undertake a small literature review, what’s PiFu alternatives as well as state of the art implementations of human digitization.
- Expanding the body of research and proposing new ways or methods to improve the final output , providing higher quality meshes as well as complex set of texture: normal maps, albedo and potentially ambient occlusion maps.
While the PiFU concept works great for digitisation of human beings, it is limited in a sense that we cannot digitise any objects other than human beings. This can be considered as a great opportunity to explore the possibility of applying the same concept to achieve 3D models out of 2D images for other objects (e.g. cups,dogs,…).
Deliverables would include commented code, a demo video and a detailed report (college dissertation doc).
Computer science background preferred, experience in Machine Learning and Computer Vision would be beneficial.
