GoCV Commands
GoCV comes with various useful command line utilities, that are also examples of how to use the package.
Basic Drawing
Demonstrates the basic drawing primitives available for drawing on images.
https://github.com/hybridgroup/gocv/blob/release/cmd/basic-drawing/main.go
Caffe Classifier
Capture video from a connected webcam, then use the Caffe deep learning framework to classify whatever is in front of the camera.
https://github.com/hybridgroup/gocv/blob/release/cmd/caffe-classifier/main.go
Capture test
Tests to verify you can capture video from a connected webcam.
https://github.com/hybridgroup/gocv/blob/release/cmd/captest/main.go
Capture window
Capture video from a connected webcam and display the video in a Window.
https://github.com/hybridgroup/gocv/blob/release/cmd/capwindow/main.go
Counter
Capture video from a pre-recorded file, and then count the number of detected objects that cross a user-definable vertical or horizontal line.
https://github.com/hybridgroup/gocv/blob/release/cmd/counter/main.go
DNN Detection
Use a Deep Neural Network to detect and track objects or faces.
https://github.com/hybridgroup/gocv/blob/release/cmd/dnn-detection/main.go
DNN Pose Detection
Use a Deep Neural Network trained using OpenPose to detect and track human body poses.
https://github.com/hybridgroup/gocv/blob/release/cmd/dnn-pose-detection/main.go
DNN Style Transfer
Use a Deep Neural Network to perform real-time style transfer.
https://github.com/hybridgroup/gocv/blob/release/cmd/dnn-style-transfer/main.go
Faceblur
Captures video from a connected camera, then uses the CascadeClassifier to detect faces, blurs them using a Gaussian blur, then displays the blurred video in a window.
https://github.com/hybridgroup/gocv/blob/release/cmd/faceblur/main.go
Facedetect
Captures video from a connected camera, then uses the CascadeClassifier to detect faces, and draw a rectangle around each of them, before displaying them within a Window.
https://github.com/hybridgroup/gocv/blob/release/cmd/facedetect/main.go
Facedetect from URL
Using a single image downloaded from a URL, it then uses the CascadeClassifier to detect faces, and draw a rectangle around each of them, before displaying them within a Window.
https://github.com/hybridgroup/gocv/blob/release/cmd/facedetect/main.go
Feature Matching
Match features in an image using the SIFT algorithm.
https://github.com/hybridgroup/gocv/blob/release/cmd/feature-matching/main.go
Find Chessboard
Find chessboard in an image using FindChessboardCorners.
https://github.com/hybridgroup/gocv/blob/release/cmd/find-circles/main.go
Find Circles
Find circles in an image using the Hough transform.
https://github.com/hybridgroup/gocv/blob/release/cmd/find-circles/main.go
Find Lines
Find lines in an image using the Hough transform.
https://github.com/hybridgroup/gocv/blob/release/cmd/find-lines/main.go
Hand Gestures
Count the number of fingers being held up in front of the camera by looking for convexity defects.
https://github.com/hybridgroup/gocv/blob/release/cmd/hand-gestures/main.go
Hello
The "hello world" of computer vision.
https://github.com/hybridgroup/gocv/blob/release/cmd/hello/main.go
Image Similarity
Compute and compare perceptual hashes for a pair of images, with a variety of algorithms.
https://github.com/hybridgroup/gocv/blob/release/cmd/img-similarity/main.go
MJPEG Streamer
Opens a video capture device, then streams MJPEG from it that you can view in any browser.
https://github.com/hybridgroup/gocv/blob/release/cmd/mjpeg-streamer/main.go
Motion Detection
Opens a video capture device, then processes it looking for motion, human or otherwise.
https://github.com/hybridgroup/gocv/blob/release/cmd/motion-detect/main.go
Save Image
Capture a single frame from a connected webcam, then save it to an image file on disk.
https://github.com/hybridgroup/gocv/blob/release/cmd/saveimage/main.go
Save Video
Capture video from a connected camera, and save 100 frames worth to a video file on disk.
https://github.com/hybridgroup/gocv/blob/release/cmd/savevideo/main.go
Show Image
Open an image file from disk, then display it in a window.
https://github.com/hybridgroup/gocv/blob/release/cmd/showimage/main.go
SSD Face Detection
Advanced Deep Neural Network example that uses SSD classifier to detect faces from a connected camera.
https://github.com/hybridgroup/gocv/blob/release/cmd/ssd-facedetect/main.go
Tensorflow Classifier
Capture video from a connected webcam, then use the Tensorflow machine learning framework to classify whatever is in front of the camera.
https://github.com/hybridgroup/gocv/blob/release/cmd/tf-classifier/main.go
Tracking
Example of using Tracker from OpenCV Contrib to track any region of interest selected by the user using the TrackerMOSSE algorithm using the connected camera.
https://github.com/hybridgroup/gocv/blob/release/cmd/tracking/main.go
Version
Displays the current version of OpenCV that is being used by GoCV.
https://github.com/hybridgroup/gocv/blob/release/cmd/version/main.go
XPhoto
This example demonstrates a couple different uses of the XPhoto module. It can use the GrayworldWB class with BalanceWhite image to save an image file on disk. It can also use the Inpaint functions with inpaint algorithms type to save an image file on disk.
