Manipulation Planning using Pushing or Pulling Primitives
Abstract: Humans manipulate objects using a wide range of actions, such as grasping, pushing, pulling, in-hand rolling, and more. This observation has lead to much research about modeling and learning individual manipulation actions. To better understand the impact of action models on planning and executing manipulation actions, we applied manipulation planning with pushing and pulling [...]
Event Cameras: Image Reconstruction, Convolutions and Color
Abstract: Event cameras are novel, bio-inspired visual sensors, whose pixels output asynchronous and independent timestamped spikes at local intensity changes, called ‘events’. Event cameras offer advantages over conventional frame-based cameras in terms of latency, high dynamic range (HDR) and temporal resolution. Event cameras do not output conventional image frames, thus, image reconstruction from events enables [...]

Title: Inverse Reinforcement Learning for Autonomous Ground Navigation Using Aerial and Satellite Observation Data Abstract: Inverse Reinforcement Learning(IRL) is a supervised learning paradigm where a learner observes expert demonstrations to learn the hidden cost function to mimic the expert's behavior. Eliminating the need for elaborate feature engineering, deep IRL approaches have been gaining interests [...]
From Farm to Takeoff: Ground and Aerial Robots for Biological Systems Analysis
Abstract: Biological and agricultural environments are dynamic, unstructured, and uncertain, posing challenges for environmental data collection at the necessary spatial and temporal scales to enable meaningful systems analysis. Small unmanned systems, however, can overcome some of these challenges by enabling autonomous or human-assisted image-based and in situ environmental data collection. This talk will present a suite of [...]

Title: Detecting objects in videos under occlusion Abstract: While object detection in videos has received a lot of attention in the past few years, most existing methods in this domain do not target detecting objects when they are occluded. However, being able to detect or track an object of interest through occlusion has been [...]

Title: Detailed Image Captioning with Hierarchical Attention Abstract: Automatic image description is the task of generating a natural sentence which reflects the visual content of an image. A lot of deep learning architectures have been explored in the past few years. While researchers have made great improvement on generating syntactically correct sentences by learning from [...]

Analysis of Spatio-Temporally Varying Features in Optical Coherence Tomographic (OCT) and Ultrasound (US) Image Sequences
Abstract: Optical Coherence Tomography (OCT) and Ultrasound (US) are non-ionizing and non-invasive imaging modalities that are clinically used to visualize anatomical structures in the body. OCT has been widely adopted in clinical ophthalmology due to its micron-scale resolution to visualize in-vivo structures of the eye. Ultra-High Frequency Ultrasound (UHFUS) captures images of tissue at a [...]

Title: Inching for Planetary Rovers Abstract: . Inching, also called push-rolling, is method of moving for vehicles that can change the position of their wheels relative to their body. Like an inchworm, it is possible to hold some wheels stationary while advancing the others and the body. In this research a test apparatus capable [...]

Title: Improving Scalability in Multi-Robot Systems with Abstraction and Specialization Abstract: Planning and controlling multi-robot systems is challenging due to high dimensionality. When the number of robots increases in the system, the complexity of computation grows exponentially. In this thesis, we examine the scalability problem in planning and control of the multi-robot system. We propose [...]
