Fall 2024
Computer vision tasks have seen breakthroughs in recent years thanks to the emergence of deep learning (DL). However, there exists different types of domain-shift problems that may impact the performance of DL-based methods. In low-level vision tasks, \eg, image restoration, the degradation of...

Spring 2018
We present a new algorithm to estimate depth of real-world scenes containing an object semi-submerged in water using a light field camera. Existing hand-held consumer light field cameras are well-suited for automated refocusing, depth detection in outdoor environment. However, when it comes to...

Learning Super-Resolution of Environment Matting of Transparent Objects from a Single Image
DownloadFall 2021
This thesis addresses the problem of super-resolution of environment matting of transparent objects. In contrast to traditional methods of environment matting of transparent objects, which often require a large number of input images or complex camera setups, recent approaches using convolutional...

PU-Ray: Domain-Independent Point Cloud Upsampling via Ray Marching on Neural Implicit Surface
DownloadFall 2024
While recent advancements in deep-learning point cloud upsampling methods have improved the input to intelligent transportation systems, they still suffer from issues of domain dependency between synthetic and real-scanned point clouds. This thesis addresses the above issues by proposing a new...

Spring 2016
For years, panoramic image stitching has been an interesting problem for re- searchers. Several advances have been made in stitching images that are ac- quired outside of water, but the problem has been poorly explored for under- water images. Image stitching for underwater images can be used in...
