Action Recognition in Videos Using Nonnegative Tensor Factorization

Abstract: Recognizing human actions is of vital interest in video surveillance or ambient assisted living. We consider an action as a sequence of body poses which are themselves a linear combination of body parts. In an offline procedure, nonnegative tensor factorization is used to extract basis images that represent body parts. The weighting coefficients are obtained by filtering a frame with the set of basis images. Since the basis images are obtained from nonnegative tensor factorization, they are separable and filte… Show more

“…Having such a tensor filled with the data acquired from running the hyperheuristic for a short time and decomposing it, hopefully reveals the indices of low level heuristics which are performing well with the underlying hyper-heuristic and acceptance criteria. This is very similar to what has been done in [32], except that, instead of examining the video of human body motion and looking for different body parts moving in harmony, we examine the trace of a hyperheuristic (body motion) and look for low level heuristics (body parts) performing harmoniously. Naturally, our ultimate goal is to exploit this knowledge for improving the search process.…”

“…Since their introduction, tensorial approaches have been employed and greatly contributed to a variety of research areas such as computer vision (Vasilescu and Terzopoulos, 2002), video processing (Krausz and Bauckhage, 2010), data compression (Wang et al, 2009), Signal Processing (Cichocki et al, 2014) and web mining (Acar et al, 2009), (Zou et al, 2015). Various problems produce data of high order of dimensionality in nature and tensors, as multidimensional arrays, are fully suited to represent such data.…”
