Title: Multimodal Image Analysis for Intelligent Visual Understanding
Abstract: Images captured using different modalities can provide different and useful information about the same object or scene. My research focuses on using this complementary information together through multimodal image analysis and fusion to improve image understanding. In this talk, I will briefly discuss how images from multiple modalities can be combined using image processing, machine learning, and deep learning techniques. I will also highlight some of the challenges involved, such as differences in image quality, resolution, contrast, and noise. The talk will present how multimodal approaches can provide better and more meaningful information compared to using a single image modality.
Short bio of the speaker: Dr. Shrida Kalamkar is associated with DES Pune University and has more than 12 years of teaching experience and over 5 years of research experience. Her areas of interest include Image Processing, Computer Vision, Artificial Intelligence, Machine Learning, and Multimodal Image Analysis and Fusion. Her research focuses on developing effective computational techniques for combining information from multiple image modalities for improved image analysis and understanding. She is also actively involved in teaching, student mentoring, research, and interdisciplinary academic activities. She is a member of IEEE and IEEE Women in Engineering (WIE) and is interested in promoting research, innovation, and opportunities for students in emerging technologies.

Title: Color Imaging and Rendering for Fluorescent Objects
Abstract: Fluorescent objects are commonly found in everyday life today. The fluorescent effect improves the visual appearance of the object surfaces. In particular, many fluorescent surfaces appear brighter and more vivid than the original object color based on the surface light reflection. Fluorescent objects exhibit not only reflection but also luminescence, so there are no easy measuring and imaging methods or devices available. Also, image rendering of fluorescent objects is currently not easy. In this lecture, I first show you various fluorescent objects found in our everyday life and in nature. The Donaldson matrix is useful to characterize the two-dimensional wavelength characteristics of a fluorescent object, which is independent of illumination. Second, I present a method for estimating the Donaldson matrix from image data of a fluorescent object captured with a spectral camera. Third, I present a technique for appearance synthesis of fluorescent objects with mutual illumination effect. The appearance synthesis model suggests that the overall appearance is decomposed into five components. Finally, I will demonstrate rendering results to synthesize appearances of fluorescent objects using the Mitsuba renderer.
