FIR-based Future Trajectory Prediction in Nighttime Autonomous Driving

1 code implementation31 Mar 2023 Alireza Rahimpour, Navid Fallahinia, Devesh Upadhyay, Justin Miller

In order to minimize false collision warnings, in our multi-step framework, first, the large animal is accurately detected and a preliminary risk level is predicted for it and low-risk animals are discarded.

Using simulation to quantify the performance of automotive perception systems

no code implementations2 Mar 2023 Zhenyi Liu, Devesh Shah, Alireza Rahimpour, Devesh Upadhyay, Joyce Farrell, Brian A Wandell

The simulation can be used to characterize system performance or to test its performance under conditions that are difficult to measure (e. g., nighttime for automotive perception systems).

Person Re-identification Using Visual Attention

no code implementations23 Jul 2017 Alireza Rahimpour, Liu Liu, Ali Taalimi, Yang song, Hairong Qi

Despite recent attempts for solving the person re-identification problem, it remains a challenging task since a person's appearance can vary significantly when large variations in view angle, human pose, and illumination are involved.

End-to-end Binary Representation Learning via Direct Binary Embedding

no code implementations15 Mar 2017 Liu Liu, Alireza Rahimpour, Ali Taalimi, Hairong Qi

Furthermore, in the effort of handling multilabel images, we design a joint cross entropy loss that includes both softmax cross entropy and weighted binary cross entropy in consideration of the correlation and independence of labels, respectively.
