Paper: Strategies to Optimize the LU Factorization Algorithm in Multicore Computers

This paper presents a series of alternatives for the parallelization of the LU factorization algorithm and its results; it was intended to run on a multicore system. The study presents complex strategies that merge the double levels of parallelism with asynchronous scheduling—the results reaching up to the state-of-the-art field levels and may go even further.

Paper: Minimizing Hallucinations in a Histogram of Oriented Gradients

In this paper, we showed that an incautious application of L-like norms to the HOG descriptor might produce a hallucination effect. To overcome this issue, we propose a new normalization scheme that effectively minimizes this undesired effect. We validated our approach on person re-identification and action recognition, demonstrating a significant boost in the performance.
