Properties

grayscale

• grayscale?: boolean

When true, convert to grayscale before running the detector. Default false.

method

• method?: FeatureDetectMethod

Detector backend, e.g. FeatureDetectMethod.SIFT (runtime default).

region

• region?: Region

Restrict detection to a rectangle; omit to use the full image.

scale

• scale?: number

Uniform scale factor applied before detection (e.g. 0.5 = half width/height) to trade accuracy for speed.
