| 中文简介: |  此演讲提供了一种方便的图形工具，用于将视觉图案（例如图像斑块和图像原子）编码为在感知特征和清晰的几何解释所跨越的空间中的点星座。通过在庞加莱球上对光波的偏振态进行编码，提出了一般理论和实用的模式编码方案。这种新的模式编码方案可用于图像处理和计算机视觉中的许多应用。在此，举例说明了三种可能的应用，它们可以在感知上相似的模式进行聚类，可视化所学习的图像原子词典的属性以及根据球形代码生成图像原子的新词典。 |
| 课程简介: | This talk presents a convenient graphical tool for encoding visual patterns (such as image patches and image atoms) as point constellations in a space spanned by perceptual features and with a clear geometrical interpretation. General theory and a practical pattern encoding scheme are presented, inspired by encoding polarization states of a light wave on the Poincare sphere. This new pattern encoding scheme can be useful for many applications in image ´ processing and computer vision. Here, three possible applications are illustrated, in clustering perceptually similar patterns, visualizing properties of learned dictionaries of image atoms and generating new dictionaries of image atoms from spherical codes. |
