GoCV Commands

GoCV comes with various useful command line utilities, that are also examples of how to use the package.

ASCIIcam

Capture video from a connected webcam, and display it in the current terminal window in ASCII format.

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.

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
