Course objectives and contents

For various phenomena related to varied phenomena, different types of data in functional and binary forms are available across spatial, spectral and temporal resolutions. To address the intertwined topics—like pattern retrieval, pattern analysis, spatial reasoning, and simulation and modelling for understanding spatiotemporal behaviours of such phenomena and processes that could be acquired through wide ranging mechanisms—various original algorithms and modelling techniques that are mainly based on mathematical morphology (originally founded by Matheron 1975, Serra 1982, 1988, and subsequent works by Soille 2003, Najman and Talbot 2010, Sagar 2013) are available.
This course presents fundamentals of mathematical morphology and scaling theories and their applications to address the aforementioned intertwined topics. The information that follows includes a brief syllabus on mathematical morphology and applications, tentative lecture titles, broad categorization of mathematical morphology, instructor's bio, and time-schedules of this one-week long course.

2) Fundamental morphological operators: Erosion, Dilation, Opening, Closing. Binary Vs Greyscale morphological operations.          

3) Hit-or-miss transform, skeletons, morphological reconstructions, thinning, thickening: Hit-or-Misstransformation, Skeletonization, Coding of binary image via skeletonization, skeletonization by influence zones (SKIZ), weighted SKIZ, Medial Axis Transformation (MAT), skeletonization via Euclidean distance Transformation, Partial skeletons, Morphological shape decomposition (MSD), Morphological thinning, thickening, pruning, MSD Vs SKIZ. 

4) Granulometry, classification, texture analysis: Binary and greyscale granulometries, pattern spectra analysis (shape-size spectrum), physical significance of granulometries, Linear granulometries, Rectangular ranulometries.
