boost::gil::threshold_binary

Applies fixed threshold to each pixel of image view. Performs image binarization by thresholding channel value of each pixel of given image view. This variant of threshold_binary automatically deduces maximum value for each channel of pixel based on channel type. If direction is regular, values greater than threshold_value will be set to maximum numeric limit of channel else 0. If direction is inverse, values greater than threshold_value will be set to 0 else maximum numeric limit of channel.

Synopsis

Declared in <boost/gil/image_processing/threshold.hpp>

template<
    typename SrcView,
    typename DstView>
void
threshold_binary(
    SrcView const& src_view,
    DstView const& dst_view,
    channel_type<DstView>::type threshold_value,
    threshold_direction direction = threshold_direction::regular);

Parameters

Name

Description

direction

Direction of image segmentation. The direction specifies which pixels are considered as corresponding to object and which pixels correspond to background.
