Abstract

The invention discloses a video image stabilizing method based on sparseness and fidelity restraining. The video image stabilizing method based on the sparseness and fidelity restraining comprises a first step of achieving segmentation for a video frame, wherein a certain number of coincident frames are arranged between segments; a second step of selecting a feature point pair between current adjacent frames, a third step of achieving overall outlier removing for the feature pair, a fourth step of fitting a two-dimensional linear motion model through utilizing the obtained feature point pair, a fifth step of estimating an original camera route, a sixth step of confirming the objective function of a smooth route and restraining conditions which restrain the changes of the original camera route, a seventh step of obtaining a captured window transformation matrix according to the solution to linear planning, an eighth step of removing the nonlinear effect in video, and a ninth step of transforming an original frame through utilizing the captured window transformation matrix. The video image stabilizing method based on the sparseness and fidelity restraining reduces video jitter, and can reduce video content distortion degree according to the requirement of a user at the same time. In addition, the video image stabilizing method based on the sparseness and fidelity restraining has a good effect on long video image stabilization.

Description

technical field [0001] The invention relates to a video stabilization method that can be widely used in consumer electronic products such as mobile phones, digital cameras, video cameras, etc., and can also be used in camera and monitoring systems equipped with drones, ships, etc. A Video Stabilization Method Based on Sparsity and Fidelity Constraints. Background technique [0002] Video stabilization refers to the use of related equipment or algorithms to make the original video sequence collected by video equipment more stable or to stabilize the original sequence to remove the jitter. The purpose of video image stabilization, on the one hand, is to improve the user's viewing comfort, and on the other hand, it is used as a preprocessing step for other video processing tasks, such as object tracking, object detection, and video compression, which can improve the accuracy and accuracy of these processing tasks. robustness. No matter from which aspect, video image stabiliza...
