Brandify, Online Addition of Logo on Background of an Awesome Ad Image
This methodology is achievable by reusing a trained ResNet101 (transfer learning) for image segmentation, followed by image processing to find the best spot on the background to place the logo.
Virtual Try-on (Virtual Showroom, Augmented Reality with Real Garments)
The outputs are a photorealistic image of the user wearing the virtual garment and a heatmap as a realistic representation of how the garment will fit and the proper size for the specific user.
I also proposed new state-of-the-art solutions (better than photogrammetry) to scan the human body accurately.
