Real-Time Digital Image Stabilization Algorithm using Sage-Husa Filter
We propose a digital image stabilization algorithm based on improved SageHusa filter. Global motion estimation is obtained by detecting interest points from reference frame, matching points in current frame, and solving motion equations. The motion includes intentional camera scan and unwanted jitter; therefore, we need to smooth global motion sequence to remove jitter. The Sage-Husa filter is ...
متن کاملReal-Time Digital Image Stabilization Using Kalman Filters
T his paper presents a novel, real-time stabilization system that uses Kalman filters to remove short-term image fluctuations with retained smooth gross movements. The global camera motion is defined in terms of constant acceleration motion and constant velocity motion models, and Kalman filtering is employed to facilitate smooth operation. It is shown that the process noise variance has a dire...
متن کاملA Robust Nonlinear Observer for Real-Time Attitude Estimation Using Low-Cost MEMS Inertial Sensors
This paper deals with the attitude estimation of a rigid body equipped with angular velocity sensors and reference vector sensors. A quaternion-based nonlinear observer is proposed in order to fuse all information sources and to obtain an accurate estimation of the attitude. It is shown that the observer error dynamics can be separated into two passive subsystems connected in "feedback". Then, ...
متن کاملA Dual-Linear Kalman Filter for Real-Time Orientation Determination System Using Low-Cost MEMS Sensors
To provide a long-time reliable orientation, sensor fusion technologies are widely used to integrate available inertial sensors for the low-cost orientation estimation. In this paper, a novel dual-linear Kalman filter was designed for a multi-sensor system integrating MEMS gyros, an accelerometer, and a magnetometer. The proposed filter precludes the impacts of magnetic disturbances on the pitc...
متن کاملReal-Time Video Stabilization for Unmanned Aerial Vehicles
This paper presents a new real-time video stabilization method for Unmanned Aerial Vehicles (UAV). It mainly consists of three steps. Firstly, the keypoints are located based on FAST corner detection and preliminarily matched. Secondly, the matched keypoints are then involved for estimation of affine transform to reduce false matching keypoints. Finally, motion estimation is performed based on ...
