Title: Quaternion Neural Networks:  A Novel Framework for Robust Scene Perception in Self-Driving Cars


Abstract: Environment perception is crucial for safe autonomous driving, but it is often compromised by unpredictable impairments such as illumination, noise, and severe weather conditions. These impairments affect the performance of vision algorithms that handle tracking, detection, and segmentation tasks. This keynote talk presents Quaternion Neural Networks (QNNs) as a novel framework to overcome this challenge. QNNs operate on quaternion numbers, the four-dimensional generalizations of complex numbers, and have several benefits over real-valued neural networks. They process multidimensional inputs, capture internal dependencies such as between the color channels of an image pixel, model structural relations, reduce parameters, and avoid overfitting. The talk covers basics, such as quaternion convolutional and recent QNN transformers. It highlights their application in scene perception for self-driving cars under foggy, cloudy, and rainy environments. Attendees will see how QNNs surpass real-valued networks in weather removal and scene segmentation tasks.

Title: Annotation-Efficient Deep Learning for Medical Image Segmentation


Abstract: Pixel-level annotation is an expensive process and has been one of the key challenges in developing deep learning based image segmentation. The problem is even more challenging for medical images because medical professional is required for annotation and normally abnormal regions in medical images are relatively small. In this talk, I will briefly give an overview of existing approaches in annotation-efficient deep learning for medical image segmentation. After that, I will report our approach by leveraging synthetic medical images. In specific, I will share three recent research works, namely weakly supervised learning using information extracted from radiology reports, synthetic-to-real test time training for source-free unsupervised domain adaption, and pseudo label guided image synthesis for semi-supervised learning. Finally, I will discuss the research directions towards annotation-free medical image segmentation.

Title: Development of Land Cover Monitoring System using Simultaneous Multi-pixel Classification Strategy based Deep Neural Architecture


Abstract: Deep neural network based classification of satellite images have become an emerging area of research in recent years as it provides highly efficient ways to classify and interpret satellite imagery. Satellite images provide valuable information about the Earth's surface, such as land cover, vegetation, urban areas, and water bodies. By leveraging deep neural networks, it is possible to analyse and categorize these images with high accuracy and efficiency. Microwave remote sensing encompasses its benefits of providing cloud-free, all-weather images and images of day and night. Synthetic Aperture Radar (SAR) images own this characteristic which promoted the use of SAR and PolSAR images in land cover classification and various other applications for monitoring land use.

As part of a bigger project on land cover classification from polarimetric SAR images, I  worked successfully on classification of vegetation areas growing diverse types of crops by designing a novel Convolutional Neural Network namely, Crop-Net, which facilitates simultaneous classification of multiple pixels located within an image patch taking into account the inter-relation between the scattering properties of neighbouring pixels. The efficiency of the designed network is validated using both publicly available data and real-field data and over-whelming performances are obtained in both cases.
