(from GStreamer Bad Plug-ins)

Name | Classification | Description
--- | --- | ---
cameracalibrate | Filter/Effect/Video | Performs camera calibration by having it point at a chessboard pattern using upstream/downstream cameraundistort
cameraundistort | Filter/Effect/Video | Performs camera undistort
cvdilate | Transform/Effect/Video | Applies cvDilate OpenCV function to the image
cvequalizehist | Transform/Effect/Video | Applies cvEqualizeHist OpenCV function to the image
cverode | Transform/Effect/Video | Applies cvErode OpenCV function to the image
cvlaplace | Transform/Effect/Video | Applies cvLaplace OpenCV function to the image
cvsmooth | Transform/Effect/Video | Applies cvSmooth OpenCV function to the image
cvsobel | Transform/Effect/Video | Applies cvSobel OpenCV function to the image
cvtracker | Filter/Effect/Video | Performs object tracking on videos and stores it in video buffer metadata.
dewarp | Filter/Effect/Video | Dewarp fisheye images
disparity | Filter/Effect/Video | Calculates the stereo disparity map from two (sequences of) rectified and aligned stereo images
edgedetect | Filter/Effect/Video | Performs canny edge detection on videos and images.
faceblur | Filter/Effect/Video | Blurs faces in images and videos
facedetect | Filter/Effect/Video | Performs face detection on videos and images, providing detected positions via bus messages
grabcut | Filter/Effect/Video | Runs Grabcut algorithm on input alpha. Values: BG=0, FG=1, PR_BG=2, PR_FGD=3; NOTE: larger values of alpha (notably 255) are interpreted as PR_FGD too. IN CASE OF no alpha mask input (all 0's or all 1's), the 'face' downstream event is used to create a bbox of PR_FG elements. IF nothing is present, then nothing is done.
handdetect | Filter/Effect/Video | Performs hand gesture detection on videos, providing detected hand positions via bus message and navigation event, and deals with hand gesture events
motioncells | Filter/Effect/Video | Performs motion detection on videos and images, providing detected motion cells index via bus messages
opencvtextoverlay | Filter/Effect/Video | Write text on the top of video
retinex | Filter/Effect/Video | Multiscale retinex for colour image enhancement
segmentation | Filter/Effect/Video | Create a Foregound/Background mask applying a particular algorithm
skindetect | Filter/Effect/Video | Performs non-parametric skin detection on input
templatematch | Filter/Effect/Video | Performs template matching on videos and images, providing detected positions via bus messages.
