Abnormal Behaviors

This paper introduces a high-speed vision system called IDP Express, which can execute real-time image processing and High-Frame-Rate (HFR) video recording simultaneously. In IDP Express, 512×512 pixel images from two camera heads and the processed results on a dedicated FPGA (Field Programmable Gate Array) board are transferred to standard PC memory at a rate of 1000 fps or more. Owing to the simultaneous HFR video processing and recording, IDP Express can be used as an intelligent video logging system for long-term high-speed phenomenon analysis. In this paper, a real-time abnormal behavior detection algorithm was implemented on IDP-Express to capture HFR videos of crucial moments of unpredictable abnormal behaviors in high-speed periodic motions. Several experiments were performed for a high-speed slider machine with repetitive operation at a frequency of 15 Hz and videos of the abnormal behaviors were automatically recorded to verify the effectiveness of our intelligent HFR video logging system.

Mission Critical

With the standardization of ultra-high-definition formats and their increasing adoption within the multimedia industry, it has become vital to investigate how such a resolution could impact the quality of experience with respect to mission-critical communication systems. While this standardization enables improved perceptual quality of video content, how it can be used in mission-critical communications remains a challenge, with the main challenge being processing. This chapter discusses the challenges and potential solutions for the deployment of ultra-high-definition video transmission for mission-critical applications. In addition, it examines the state-of-the-art solutions for video processing and explores potential solutions. Finally, the authors predict future research directions in this area.

Potential Use

Scanning MEMS (micro-electro-mechanical system) mirrors are attractive given their potential use in a diverse array of laser scanning display and imaging applications. Here we report on an electrostatic MEMS mirror for high definition and high frame rate (HDHF) Lissajous scanning. The MEMS mirror comprised a low Q-factor inner mirror and frame mirror, which provided two-dimensional scanning at two similar resonant scanning frequencies with high mechanical stability. The low Q inner mirror enabled a broad frequency selection range. The high definition and high frame rate (HDHF) Lissajous scanning of the MEMS mirror was achieved by selecting a set of scanning frequencies near its resonance with a high greatest common divisor (GCD) and a high total lobe number. The MEMS mirror had resonant scanning frequencies at 5402 Hz and 6702 Hz in x and y directions, respectively. The selected pseudo-resonant frequencies of 5450 Hz and 6700 Hz for HDHF scanning provided 50 frames per second with 94% fill factor in 256 × 256 pixels. This Lissajous MEMS mirror could be utilized for assorted HDHF laser scanning imaging and display applications.

Less Is More

What is realism in film? Focusing on a test case of High Frame Rate (HFR) high-definition movies, I discuss in this article various types of realism as well as their inter-relations. Precision, recessiveness of the medium, transparency, and ‘Collapse’ are discussed and compared. At the end of the day, I defend the claim that ‘less is more’ in the sense that more image precision can actually have a negative impact on storytelling.
