Large Scale Visual Data Analytics for Geospatial Applications

Abstract: The widespread availability of high resolution aerial imagery covering wide geographical areas is spurring a revolution in large scale visual data analytics. Specifically, modern aerial wide area motion imagery (WAMI) platforms capture large high resolutio n at rates of 1-3 frames per second. The sequences of images, which individually span several square miles of ground area, represent rich spatio-termporal datasets that are key enablers for new applications. The effectiveness of such analytics can be enhanced by combining WAMI with alternative sources of rich geo-spatial information such as road maps or prior georegistered images. We present results from our recent research in this area covering three topics. First, we describe a novel method for pixel accurate, real-time registration of vector roadmaps to WAMI imagery based on moving vehicles in the scene. Next, we present a framework for tracking WAMI vehicles across multiple frames by using the registered roadmap and a new probabilistic framework that allows us to better estimate associations across multiple frames in a computationally tractable algorithm. Finally, in the third part, we highlight, how we can combine structure from motion and our proposed registration approach to obtain 3D georegistration for use in application such as change detection. We present results on multiple WAMI datasets, including nighttime infrared WAMI imagery, highlighting the effectiveness of the proposed methods through both visual and numerical comparisons. The talk particularly highlights how image processing and computer vision applications are a fertile ground for incorporating machine learning and data science methodologies

Nanowires and 2D Materials in Practice – Visibility, Doping and Device Investigation

Abstract: Starting from the first exfoliated graphene flakes in 2004, 2D materials have conquered a broad field of possible future applications. Among these, 2D material based circuits and sensors are very promising candidates for a contemporary industrial adoption. Nevertheless, there are many challenges to master before the goal of a profitable economic adjustment can be achieved. Therefore, the talk focuses on the possibility of a 2D material and nanowire assimilation that allows an analysis by the help of buried chip structures.

Cellular Dimensional Picoliter Microsensing in Fiber Optics

Abstract: In photonic applications, miniaturized fiber sensors at the length of 100 um scale have been found to helpful for ultra -tiny sample volume microsensing. Conventionally, the popular fiber-optic sensors are based on fiber Bragg gratings, long period gratings, Sagnac loop interferometers, Fabry-Perot interferometers,Michelson interferometers, and Mach-Zehnder interferometers. However, those interferometric sensors are usually with a device length of longer than a few centimeters, which is disadvantageous to achieve the high accuracy measurements for ultra-weak signals or tiny sample volume. In this talk, the fiber abrupt tapering technique is the fabrication method which breaks the adiabatic waveguiding in fiber core and transforms fractional power of the core mode into cladding modes will be introduced to achieve the miniaturized and integrated fiber components. By introducing two adjacent abrupt tapers in a highly Er/Yb codoped silica fiber using a focused CO2 laser beam to make micro Mach - Zehnder interferometer (MZI), the minimum device length achieved can be as short as 180 um. Fractio nal power of the core mode is coupled to excite the cladding modes through the first abrupt taper and the residual core mode and the excited cladding modes thus propagate through the different optical paths. The cladding modes and the core mode meet up at the second abrupt taper to produce interferences. The cladding modes can sense the ambient index variations of the external material coating at the phase shifter or at the abrupt tapers. This micro MZI can be used to detect the micro index variation of 0.002 under a 6.3 picoliter of liquid volume. In addition, the monolithic miniaturized Michelson interferometers based on core-cladding modes interferences for picoliter sample volume microsensing will also be introduced.

Creating Autonomous Vehicle Systems

Abstract: This talk is a technical overview of autonomous vehicles where we share our practical experiences of creating autonomous vehicle systems. Autonomous vehicle systems are complex, consisting of three major subsystems: algorithms for localization, perception, and planning and control; client systems, such as the robotics operating system and hardware platform; and the cloud platform, which includes data storage, simulation, high-definition (HD) mapping, and deep learning model training. The algorithm subsystem extracts meaningful information from sensor raw data to understand its environment and make decisions about its actions. The client subsystem integrates these algorithms to meet real-time and reliability requirements. The cloud platform provides offline computing and storage capabilities for autonomous vehicles. Using the cloud platform, we are able to test new algorithms and update the HD map - plus, train better recognition, tracking, and decision models.

Image processing with Dipole-Coupled Multiferroic Nanomagnet Arrays

Abstract: Hardware-based image processing, without the involvement of any software, offers orders of magnitude improvement in speed and energy cost. In such paradigms, the image processing activity is elicited from interactions between passive devices, each encoding a pixel state, that are arranged in such a way as to perform specific image processing tasks. A 2-D periodic array of dipole-coupled elliptical magnetostrictive nanomagnets, delineated on a piezoelectric substrate, can execute a variety of image processing functions, such as image de-noising, image re-construction, pattern recognition and edge enhancement detection. Each nanomagnet has two stable magnetization states that encode pixel color (black or white). An image containing black and white pixels is first converted to corresponding voltage states (high and low) and then mapped into the magnetization states of the nanomagnets with magneto-tunneling junctions (MTJs). The same MTJs are employed to read out the processed pixel colors later. Dipole interaction between the nanomagnets ensures that when the system is perturbed/excited and then allowed to relax to the ground state, the final magnetization states of the nanomagnets (or, equivalently, the pixel colors) conform to the desired processed image. This is "physics-based processing" where the physics of the inter-nanomagnet interaction, rather than any software or instruction sets, accomplishes the processing function. In our case, the image processing activity is triggered by applying a global strain to the nanomagnets with a voltage dropped across the piezoelectric substrate. The strain perturbs the magnetization of the magnetostrictive nanomagnets taking them to an excited state. When the strain is removed, the magnetizations relax to the collective ground state and in the process assume configurations that correspond to processed pixels. An image containing an arbitrary number of black and white pixels can be processed in few nanoseconds with very low energy cost.
