Deep Learning-based Image Watermarking

Image watermarking refers to the process of embedding a watermark into a cover-image. Our watermarking focuses on the robustness for covert communication. One application is to extract the watermark from camera-resampled marked-images, and the end-users can scan any images for more information. Deep Learning components will be designed or applied.

(Deep) Weakly Supervised Learning

Labeling an image as a whole is much easier than labeling each part. However, supervised learning can only learn from training data with exact labels. Hence, weakly supervised learning, more concretely, inexact supervision where the training data are given with labels but not as exact as desired, is the purpose of this project. Here, the given label will the classification label, and the desired output will range from object localization to detection to segmentation.

Deep Learning-based Foreign Object Debris Detection

Foreign Object Debris is any substance alien to an airport system that can cause damage. We leverage multidisciplinary techniques by integrating machine learning, computer vision, small unmanned aerial technology, and traditional airport operations protocols to develop a system that helps overcome the high-cost, low-efficiency, and technical challenges of Foreign Object Debris detection that a great number of small-scale airports are facing.
