template<typename T >
void | cinder::ip::threshold (SurfaceT< T > *surface, T value, const Area &area)
| Thresholds surface setting any values below value to zero and any values above to unity inside the Area area.
template<typename T >
void | cinder::ip::threshold (SurfaceT< T > *surface, T value)
| Thresholds surface setting any values below value to zero and any values above to unity.
template<typename T >
void | cinder::ip::threshold (const SurfaceT< T > &srcSurface, T value, SurfaceT< T > *dstSurface)
| Thresholds srcSurface setting any values below value to zero and any values above to unity and storing the result in dstSurface.
template<typename T >
void | cinder::ip::threshold (const ChannelT< T > &srcSurface, T value, ChannelT< T > *dstSurface)
| Thresholds srcChannel setting any values below value to zero and any values above to unity and storing the result in dstChannel.

template<typename T >
void | cinder::ip::adaptiveThreshold (const ChannelT< T > &srcChannel, int32_t windowSize, float percentageDelta, ChannelT< T > *dstChannel)
| Thresholds srcChannel using an adaptive thresholding algorithm which considers a window of size windowSize pixels and stores the result in dstChannel.
template<typename T >
void | cinder::ip::adaptiveThreshold (ChannelT< T > *channel, int32_t windowSize, float percentageDelta)
| Thresholds srcChannel using an adaptive thresholding algorithm which considers a window of size windowSize pixels.
template<typename T >
void | cinder::ip::adaptiveThresholdZero (ChannelT< T > *channel, int32_t windowSize)
| Thresholds srcChannel using an adaptive thresholding algorithm which considers a window of size windowSize pixels. Equivalent to calling adaptiveThreshold with a 0 for percentageDelta.
