measure_appearance()

Kinesis::Vision::MeasureAppearanceAnalysis MayaFlux::Yantra::VisionAnalyzer::measure_appearance ( const Kinesis::Vision::VisionResult &  result, const std::shared_ptr< Core::VKImage > &  gray, uint32_t  w, uint32_t  h  )

private

MeasureAppearance's whole-frame gradient sample (region_sample.comp over result.images.sobel) and brightness histogram (otsu_histogram.comp over gray).

gray is the frame's gray image, which a sequence seeded from another lane's RgbaToGray does not produce itself, so the caller supplies it. Empty fields for whichever input image is null.
