Overview

This document describes the filter Designer's typical parameter settings in the effect package. When using OrangeFilter Designer, you may refer to these parameter settings and modify existing effect packages to meet particular service requirements.

Effect Parameters

  • Brightening (skin color adjustment): related packages: beauty_basic.zip (frosted smoothing) beauty5_basic.zip (clear smoothing).
  • Smoothing (skin smoothing): related packages: beauty_basic.zip (frosted smoothing) beauty5_basic.zip (clear smoothing).
  • Face shaping (detailed adjustment of facial features, e.g. thinning): related package: basicthinface.zip (basic shaping), faceliftingopt.zip (advanced shaping).
  • Stylistic filters (context tone, e.g. cool, warm): related package: slookuptable1-5.zip.
  • Stickers (effects and animations triggered by facial expressions and gestures): related package: face3dplane.zip, gestures.zip.

Brighten

Brightening is used to adjust human skin colors, and to achieve various beautification effects by changing color palettes.

Face Stickers

The face stickers function intelligently uses deep learning algorithms to identify face orientation and to enable sticker and animation effects.

ParameterDescription
Open Mouth TriggerWhether to trigger a sticker upon mouth opening
Close Mouth TriggerWhether to trigger a sticker upon mouth closing
Open Mouth ThresholdThreshold of sensitivity for mouth opening/closing identification, 0.0-1.0
SizeSticker size
TranslateXImage lateral offset, default is 0.0 for tracking one’s face in a central position
TranslateYImage vertical offset, default is 0.0 for tracking one’s gesture in a central position
TranslateZImage depth offset, default is 0.0 for tracking one’s gesture in a central position
RotateImage rotation, 0-360
Svgasvga file path, for rendering svga animations
Imagespng file group path, sticker composition, used to render a single png picture or png sequence frame animation
Blend ModeSemi-transparent blend mode used for rendering; supports normal blend mode for PS images
OpaticyOverall image opacity, 0.0-1.0 (0.0 = total transparency; 1.0 = total opacity)
Time IntervalAnimation frame time interval (ms), controls animation play speed
Fixed Totate XProhibit X-axis rotation
Fixed Totate YProhibit Y-axis rotation
Fixed Totate ZProhibit Z-axis rotation
Hold onShow sticker even when no face is detected

Gesture Recognition

The gesture recognition feature uses deep learning algorithms to intelligently identify user gestures and trigger related effects (e.g. taking pictures or adding stickers and animation effects).
Six gestures are currently recognized: OK, thumbs-up, heart (one or two-handed), open palm, victory, and hang loose.
