Method Details

flowKlt

public static <I extends ImageGray<I>,
D extends ImageGray<D>>
DenseOpticalFlow<I> flowKlt(@Nullable
 @Nullable ConfigPKlt configKlt,
 int radius,
 Class<I> inputType,
 Class<D> derivType)

Compute optical flow using PyramidKltTracker.

Type Parameters:

I - Input image type.

D - Derivative image type.

Parameters:

configKlt - Configuration for KLT. If null then default values are used.

radius - Radius of square region.

inputType - Type of input image.

derivType - Type of derivative image. If null then default is used.

Returns:

DenseOpticalFlow
