Semarang, April 2026 — The Master’s Program in Mathematics, Faculty of Science and Mathematics (FSM), Diponegoro University, through the Undip Global Classroom (UGC) initiative, successfully hosted an international lecture series entitled “Mathematical Modelling: Fuzzy Image Processing” on 15 and 22 April 2026. The lecture series featured Dr. Suzelawati Zenian from Universiti Malaysia Sabah, Malaysia, as the invited international speaker, with Prof. Dr. Widowati, M.Si. serving as the program coordinator. The event attracted undergraduate and postgraduate students, academic staff, and researchers interested in mathematics, artificial intelligence, and digital image processing.
The lecture series was designed to provide participants with both theoretical understanding and practical insights into the role of mathematical modelling in image-processing technologies. Throughout the two sessions, participants explored how mathematical concepts can be utilized to represent, analyze, and improve digital images in various scientific and technological applications.
During the presentations, Dr. Suzelawati explained the fundamental principles of image processing using linear algebra concepts, particularly vectors and matrices. She demonstrated how digital images can be represented as matrices containing pixel intensity values and manipulated through mathematical operations such as filtering, enhancement, compression, and transformation.
A major focus of the lectures was the application of fuzzy logic in image processing. Unlike conventional binary logic, which only uses values of 0 and 1, fuzzy logic allows intermediate values between 0 and 1. This capability enables systems to manage uncertainty more effectively and produce more flexible image analysis results. Examples discussed included image brightness classification and noise reduction in medical imaging while preserving important object boundaries.
The sessions were highly interactive, with participants actively engaging in discussions and asking questions regarding the implementation of fuzzy methods in modern digital technologies. The enthusiastic participation reflected the growing interest in mathematical modelling and artificial intelligence among students and academics.
Through the Undip Global Classroom program, Diponegoro University continues to strengthen international academic collaboration and promote globally oriented education. The activity is expected to broaden participants’ knowledge and encourage the application of mathematical modelling in addressing real-world technological challenges.
