Abstract

Videos recorded on UAVs often suffer vibration effects due to unwanted camera movements. Unstable videos make it difficult for users to observe certain targets. Therefore, this research designed a video stabilization system using image processing to reduce vibration effects in a video. The video stabilization system consists of four main processes. Firstly, a feature point detection and tracking process between two consecutive frames to get the camera movement path. This process applied Shi-Tomasi corner detector and Optical flow matching. Secondly, motion estimation is performed based on affine transform. Third, the simple low pass filter is applied to determine a motion compensation for the object movement in the video. Lastly, video frames are transformed based on compensation value to reduce the vibration effect. The test results on the implementation of the video stabilization system show video quality improvement based on a decrease in SAD level and increase the SSIM level.
