The Veremin control panel is powered by dat.GUI.

The control panel allows you to configure various settings and tweak your experience.

Below options are available for configuration in the control panel:

Global

Option Default Description
algorithm multi-pose Version of algorithm (i.e., single-pose, multi-pose) to perform the pose estimation.
outputDevice first detected MIDI output device (or browser if none) List of available output device (i.e., browser plus detect MIDI output devices)
chordIntervals minor0 Chords/notes to select from when computing the note values as defined in chord-interval.js.
noteDuration 300 Duration (in milliseconds) for how long a note is ON.
notesRangeScale 1 Scale for the range of notes in respect to the vertical zone height (i.e., 1 equals entire zone height, 0.5 equals half the zone height, etc.).
notesRangeOffset 0 Offset for the range of notes in response the the vertical zone bottom edge (i.e., 0 bottom of zone equals start of notes range, 0.5 bottom of zone equal half notes range)

Browser

Option Default Description
preset Synth1 Instrument presets for Tone.js when using the browser for audio as defined in tonejs-presets.js. Does not effect MIDI output devices.

Input

Option Default Description
mobileNetArchitecture 0.75 Corresponds to a MobileNet architecture and checkpoint. The larger the value, the larger the size of the layers, and more accurate the model at the cost of speed.
outputStride 16 Desired stride for the outputs when feeding the image through the model. The higher the number, the faster the performance but slower the accuracy.
imageScaleFactor 0.5 What to scale the image by before feeding it through the network. The lower the number, the faster the performance but slower the accuracy.

Single Pose Detection

Option Default Description
minPoseConfidence 0.1 Minimum confidence score before a pose is registered.
minPartConfidence 0.5 Minimum confidence score before a body part is registered.

Multi Pose Detection

Option Default Description
maxPoseDetections 5 Maximum number of poses to detect.
minPoseConfidence 0.15 Minimum confidence score before a pose is registered.
minPartConfidence 0.1 Minimum confidence score before a body part is registered.
nmsRadius 30.0 Non-maximum suppression part distance. Two parts suppress each other if they are less than nmsRadius pixels away.

Canvas

Option Default Description
showVideo true Whether or not to show the web camera video stream.
showSkeleton true Whether or not to show the skeletal information detected by PoseNet.
showPoints true Whether or not to show the joint information detected by PoseNet.
showZones true Whether or not to show the left and right activation zones.
