This paper introduces an efficient hardware accelerated feature extraction architecture with a high spec of 1920×1080 image resolution at 120 fps. We choose MoFREAK feature [1] to implement in our real-time action recognition system. MoFREAK is a local spatio-temporal feature, which combines the appearance and motion descriptor independently. We design a two phase architecture to balance the throughput...
Real-time information fusion based on WAMI (Wide-Area Motion Imagery), FMV (Full Motion Video), and Text data is highly desired for many mission critical emergency or military applications. However, due to the huge data rate, it is still infeasible to process streaming WAMI in a real-time manner and achieve the goal of online, uninterrupted target tracking. In this paper, a pseudo-real-Time WAMI data...
Given the rapid expansion of car ownership worldwide, vehicle safety is an increasingly critical issue in the automobile industry. The reduced cost of intelligent mobile phones has made it economically feasible to develop intelligent systems for visual-based event detection for forward collision avoidance and mitigation. In this work, a real-time traffic red light recognition is proposed under mobile...
Digital sculpting is a new trend for creating 3D models, but its application in the manipulation of volumetric data raises several issues that need to be addressed. With the extended marching cubes algorithm (EMC), sharp features of 3D models are well preserved. Additionally, the dynamic nature of modifying models in real time needs to be dealt with in sculpting applications: since the sampling of...
