My name is Eman Hassan, a PhD candidate in the school of Informatics Computing and Engineering, Indiana University, USA. My undergrad was in Electrical and Computer Engineering, school of Engineering, Ain Shams University, Cairo, Egypt. My main interest is to acquire new knowledge and employ it to create something interesting and new. I am also working towards acquiring a master degree in Mathematics while pursuing my PhD in Computer Science.

We investigate Generative Adversarial Networks (GANs) to model one particular kind of image: frames from TV cartoons. Cartoons are particularly interesting because their visual appearance emphasizes the important semantic information about a scene while abstracting out the less important details, but each cartoon series has a distinctive artistic style that performs this abstraction in different ways. We consider a dataset consisting of images from two popular television cartoon series, Family Guy and The Simpsons.
We examine the ability of GANs to generate images from each of these two domains, when trained independently as well as on both domains jointly. We find that generative models may be capable of finding semantic-level correspondences between these two image domains despite the unsupervised setting, i.e. even when the training data does not give labeled alignments between them.
We describe an object replacement approach whereby privacy-sensitive objects in videos are replaced by abstract cartoons taken from clip art. Our approach uses a combination of computer vision, deep learning, and image processing techniques to detect objects, abstract details, and replace them with cartoon clip art.
We conducted a user study (N=85) to discern the utility and effectiveness of our cartoon replacement technique. The results suggest that our object replacement approach preserves a video’s semantic content while improving its privacy by obscuring details of objects.
This work represents a fun way to generate a summarization of life logging data. The main idea is that objects always convey many information about the scene and the activity that is happening, we use mutual information to mine for important object to each activity, then we use that object area to sample frames representing the activity. Finally, we render the summary in a cartoon-like way by background cartooning and object replacements with clip arts. This could produce a possibly nice pleasing cartoon summary for an ego-centric life logging video.
We present a new inpainting algorithm that is based on image segmentation and segment classification. First, we employ the mean shift algorithm to segment the input image. Then, we divide the original inpainting problem to be either one of the two problems: Large Segment Inpainting problem or Non-uniform Segments inpainting problem.
The reason we do that is that human eye is more discerning to the errors in the structure and texture propagation of a large-uniform regions with less details while it is less discerning to errors in non-uniform regions with more details.
We propose a novel algorithm for each one of the problems- Large Segment Inpainting and Non- uniform Segments inpainting- according to the main features of each one. The experimental results show the advantage of our technique which produces output images with better perceived visual quality.
