Full searchable documentation here. This module contains a single class VidStab used for video stabilization. The foundation code was found in a comment on Nghia Ho's post by the commenter with username koala. Video used with permission from HappyLiving. If you've already built OpenCV with python bindings on your machine it is recommended to install vidstab without installing the pypi versions of OpenCV.

The opencv-python python module can cause issues if you've already built OpenCV from source in your environment. The below commands will install vidstab with opencv-contrib-python as dependencies.

The VidStab class can be used as a command line script or in your own custom python code. The method VidStab. The VidStab class can also process live video streams. The underlying video reader is cv2. VideoCapture documentation.

The relevant snippet from the documentation for stabilizing live video is:. Its argument can be either the device index or the name of a video file. Device index is just the number to specify which camera. Normally one camera will be connected as in my case. So I simply pass 0 or You can select the second camera by passing 1 and so on. VideoCapture as a device index. You can also pass a device index to the --input argument for command line usage. One notable difference between live feeds and video files is that webcam footage does not have a definite end point.

The 3 columns represent delta x, delta y, and delta angle respectively.

Sign up. A Python package to stabilize videos using OpenCV.VidGear now provides real-time Video Stabilization with minimalistic latency and at the expense of little to no additional computational power requirement with Stabilizer Class.

The basic idea behind it is to tracks and save the salient feature array for the given number of frames and then uses these anchor point to cancel out all perturbations relative to it for the incoming frames in the queue.

This stabilization feature in VideoGear can be activated with stabilize boolean flag during initialization. Note: Stabilizer Class Class provide access to the certain parameter which is as follows:. It handles the quality of stabilization at the expense of latency and sudden panning.

Larger its value, less will be panning, more will be latency and vice-versa. Its default value is Its default value is 0 no borders. Its default value is False.

Its default value is 'black'. You can easily use the real-time Video Stabilization with Vidgear's various Gears without any extra effort as follows:. This Wiki and the Readme contains a lot of detailed information, please take your time to read the information.

There is a heavily detailed Changelog and Release changes. If you run into any trouble or have any questions, then do not hesitate to report an Issue. If you think VidGear library is helpful and would like to help in return - then you can be a stargazer.

Thank you. If you would like to help the continued efforts of this project, any size donations are welcomed and highly appreciated:. Skip to content. Real time Video Stabilization Jump to bottom. Real-time Video Stabilization VidGear now provides real-time Video Stabilization with minimalistic latency and at the expense of little to no additional computational power requirement with Stabilizer Class. Features : Real-time stabilization with low latency and no extra resources. Works exceptionally well with low-frequency jitter.

Also seamlessly works standalone. Important: The stabilizer may not perform well against High-frequency jitter in video. Use at your own risk! VideoCapture 0 Open any video stream such as live webcam video stream on first index i.

Uses opencv, hugin and ffmpeg. Note: not '-l' as levelling can screw things up.Input video is read from file, put through stabilization process, and written to an output file. The process calculates optical flow cv2. The optical flow will be used to generate frame to frame transformations cv2.

Transformations will be applied cv2. This class is based on the work presented by Nghia Ho. Use the transforms generated by VidStab. This method is a wrapper for VidStab. Nothing is returned. The resulting transforms can subsequently be used for video stabilization by using VidStab. Separate subplots are used to show the x and y trajectory. Create a plot of the transforms used to stabilize the input video. Perform video stabilization a single frame at a time. Video used with permission the HappyLiving YouTube channel.

This mainly involves reducing the effect of motion due to translation or rotation or any movement in camera.

In this, Euclidean Motion Model is used instead of Affine or Homographic transformation, because it is adequate for motion stabilization. Skip to content.

Video Stabilization Using Point Feature Matching in OpenCV

We use two set of points to find rigid transform that maps previous frame to the current frame estimateRigidTranform. Once the motion is estimated, we store the rotated, translated values. We soothe the values, found in step 3 moving average filter. Calculate smooth motion between frames trajectory. Apply smoothed camera motion to frames.
