Speech Title: Light Field Imaging: Representation, Compression and Applications
Abstract: Light field is a function which is used to describe how light rays propagates through the free space and various optical components, and finally integrates into an image. Conventional cameras record a 2D projection of the light field integration, which inevitably loses a lot of information, especially with respect to each light ray’s angular direction. Owing to the extremely large amount of information the light field contains, the light field cameras are designed to resolve the light ray integration process and capture the extra directional information, which is useful in many applications. This talk will focus on recent progress in light field imaging, which includes representation, compression and new applications.

Speech Title: A Self-Reference Watermarking Scheme based on Wet Paper Coding
Abstract: Fragile watermarking is applied to protect the integrity of the digital media. Current fragile watermarking schemes mainly provide the functionality of detecting and locating the tampered regions of an authorized image. The capability to recover the tampered regions has rarely been discussed in the literature. In fact, the recovery ability is an important issue while proving and maintaining the image integrity. For achieving these purposes, we first utilize the concept of self-reference to preserve the significant information of a protected image. Then we embed the information into the protected image using the technique of wet paper coding. According to experimental results, the new scheme is highly sensitive to detect and locate the tampered area. In particular, the results show that the quality of recovery image is satisfactory.

He has published more than 100 papers in top venues. His work of multi-camera person tracking and identification was elected as one of the 13 incredible Tech innovations by the Huffington post. The system his team has developed achieved the best performance in a few international competitions, including the TRECVID LOC, the Thumos Action Recognition challenge, the MSR-Bing Image retrieval grand challenge. He is a winner of the Google Faculty Research Award, the ARC DECRA award, and the ACS gold disital disruptor.

Speech Title: Weakly Supervised Detection in Images and Videos
Abstract: Deep convolutional neural networks (CNN) achieve superior performance on many computer vision applications, e.g., detection, segmentation, and translation. Annotating a large number of images for training CNNs is tedious which costs lots of resources, especially for complex tasks, e.g., object detection and landmark detections. For example, to annotation an image for detection, one provides a bounding box for each object in images. I will talk about how to minimize the annotation cost for detection. I will first talk about how to design supervision signal, which does not require human annotating or only needs the minimum human annotations. Secondly, exemplified for object detection and facial landmark detection, I will talk how to leverage such supervision to train CNN models for different computer vision applications.
