Field Detail

Average

public static final long Average

Compute an average of all samples. This will fully utilize all samples but may lead to excessive ghosting artifacts under motion. Therefore, this is best for static images.

Constant Field Values

ExponentialMovingAverage

public static final long ExponentialMovingAverage

Compute an exponential moving average by blending linearly between the previous accumulated samples and the current sample according to the temporalReprojectionBlendFactor property. This will cause older samples to lose their contribution over time, which will prevent ghosting artifacts but will also never converge to a stable value. Therefore, this is best for images with motion.
