Local image descriptors have been developed over two decades. Representative methods such as SIFT, SURF, and LBP, have been widely used in various computer vision applications. Although popularity, these methods are either not suitable or less robust in many new applications, which emerges the development of modern local image descriptors. In this half-day tutorial, we will give an extensive introduction of the latest advances on this topic. Particularly, after a brief introduction of local descriptors and review of the classical methods, we will introduce modern approaches for local image description. We divide them into two categories: those were proposed for high matching performance, and those for high efficiency. For each category, we will introduce both hand-crafted and learning-based methods, as well as discuss their advantages and disadvantages. Moreover, we will give an introduction of benchmarks and software for performance evaluation and some typical applications.
This tutorial only requires basic knowledge of image processing, computer vision and machine learning. The lecture slides will be made available immediately during the tutorial. The source codes of most of the introduced methods will be released to the public.
