Isolated single sound lip-reading using a frame-based camera and event-based camera
Frontiers in Artificial Intelligence, 2023 Unlike the conventional frame-based camera, the event-based camera detects changes in the brightness value for each pixel over time. This research work on lip-reading as a new application by the event-based camera.

Multi-Frame Based Homography Estimation for Video Stitching in Static Camera Environments [PDF]
Sensors, 2019 In this paper, a multi-frame based homography estimation method is proposed for video stitching in static camera environments. A homography that is robust against spatio-temporally induced noise can be estimated by intervals, using feature points ...

Pose and Focal Length Estimation Using a Point and a Line With Known Camera Position
IEEE Access, 2023 2D-3D point or line correspondences are usually used to estimate the camera pose and intrinsic parameters, such as the focal length. There are many point-based methods and line-based methods, i.e., PnP solvers and PnL solvers.

Real-time event simulation with frame-based cameras
2023 IEEE International Conference on Robotics and Automation (ICRA), 2023 Event cameras are becoming increasingly popular in robotics and computer vision due to their beneficial properties, e.g., high temporal resolution, high bandwidth, almost no motion blur, and low power consumption. However, these cameras remain expensive and scarce in the market, making them inaccessible to the majority. Using event simulators minimizes

Compressive Coded Rotating Mirror Camera for High-Speed Imaging
Photonics, 2021 We develop a novel compressive coded rotating mirror (CCRM) camera to capture events at high frame rates in passive mode with a compact instrument design at a fraction of the cost compared to other high-speed imaging cameras. Operation of the CCRM camera

A Comparison Between Framed-Based and Event-Based Cameras for Flapping-Wing Robot Perception
2023 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2023 Perception systems for ornithopters face severe challenges. The harsh vibrations and abrupt movements caused during flapping are prone to produce motion blur and strong lighting condition changes. Their strict restrictions in weight, size, and energy consumption also limit the type and number of sensors to mount onboard. Lightweight traditional cameras

A novel method of object detection from a moving camera based on image matching and frame coupling. [PDF]
PLoS ONE, 2014 A new method based on image matching and frame coupling to handle the problems of object detection caused by a moving camera and object motion is presented in this paper. First, feature points are extracted from each frame. Then, motion parameters can be

Video Display Field Communication: Practical Design and Performance Analysis
IEEE Access, 2023 Display field communication (DFC) is a spectral domain-based, unobtrusive display-to-camera (D2C) communication method in which a commercially available digital display serves as the transmitter and an off-the-shelf camera serves as the receiver.
