A typical example of a relationship between neighboring pixels is the intensity order, which gives rise to some morphological tree-based image representations (e.g., Min/Max tree and tree of shapes). These trees have been shown useful for many applications, ranging from image filtering to object detection and segmentation. Yet, these intensity order based trees do not always perform well for analyzing complex natural images. The success of deep learning in many vision tasks motivates us to resort to convolutional neural networks (CNNs) for learning such a relationship instead of relying on the simple intensity order. As a starting point, we propose the flux or direction field representation that encodes the relationship between neighboring pixels. We then leverage CNNs to learn such a representation and develop some customized post-processings for several vision tasks, such as symmetry detection, scene text detection, generic image segmentation, and crowd counting by localization. This talk is based on [1] and [2], as well as extension of those previous works that are currently under review. [1] Xu, Y., Wang, Y., Zhou, W., Wang, Y., Yang, Z. and Bai, X., 2019.

After completing his Ph.D. study at LRDE, EPITA, ESIEE Paris, and LIGM, He worked at LRDE as an assistant professor (Maître de Conférences). He is currently an Associate Professor at the School of Electronic Information and Communications, HUST. His research interests include mathematical morphology, image segmentation, medical image analysis, and deep learning. L'entrée du séminaire est libre.
