Dynamic Texture with Fourier Descriptors
Bobby Abraham, Octavia Camps, Mario Sznaier · 2005
Dynamic textures encompass the class of video sequences that exhibit some stationary properties in time. Examples of such textures include ripples on water, smoke out of a chimney, waving flags etc. Recently, it has been shown that such textures can be expressed as the output of a linear dynamic system that can be identified from a sample image sequence. In this paper, we propose to identify the underlying linear dynamic system using a set of Fourier descriptors of the frames rather than the raw sequence. It is shown that this approach enhances the performance time of the learning process and only requires a much smaller learning data set. The proposed algorithm improves upon published algorithms by exploiting the inter pixel dependency, while producing similar visual
