                                     int protectedDarkOffset)

Initializes a new instance of the AutoWhiteBalanceFilterOptions class.

Parameters:

lowPercentile - The low percentile for black point, used for dark protection (default: 3).

targetHighPercentile - The target high percentile for contrast stretching (default 97).

targetValue - The target value for the high percentile (default 255).

maxScale - The maximum scaling factor for each channel (default 1.4f).

protectedDarkOffset - Offset from low percentile below which dark pixels are not stretched (protection).

Method Detail

getTargetHighPercentile

public final int getTargetHighPercentile()

Gets the target high percentile for contrast stretching. Determines which brightness percentile will be mapped to the target value.

Returns:

the target high percentile for contrast stretching.

getTargetValue

public final int getTargetValue()

Gets the target value for the high percentile. This value will be used as the white reference for contrast stretching.

Returns:

the target value for the high percentile.

getMaxScale

public final float getMaxScale()

Gets the maximum scaling factor for each channel. Restricts the amplification of any channel to avoid excessive color shifts.

Returns:

the maximum scaling factor for each channel.

getLowPercentile

public final int getLowPercentile()

The low percentile for black point, used for dark protection (default: 3).

getProtectedDarkOffset

public final int getProtectedDarkOffset()

Offset from low percentile below which dark pixels are not stretched (protection).
