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
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.
