Not all Flame implementations use density estimation. The idea is to vary the width of the filter inversely proportional to the number of samples available.Īs a result, areas with few samples and high noise become blurred and smoothed, but areas with many samples and low noise are left unaffected.
FLAM3 uses a simplification of the methods presented in *Adaptive Filtering for Progressive Monte Carlo Image Rendering*, a paper presented at WSCG 2000 by Frank Suykens and Yves D. This problem can be solved with adaptive density estimation to increase image quality while keeping render times to a minimum. One does not however want to lose resolution in the parts of the image that receive many samples and so have little noise. The noise that results from this stochastic sampling can be reduced by blurring the image, to get a smoother result in less time. The flame algorithm is like a Monte Carlo simulation, with the flame quality directly proportional to the number of iterations of the simulation. On the below half, rendered with Density Estimation, the noise is smoothed out without destroying the sharp edges.
In the above half, you can see the noise and individual samples. This is done as follows:Ī demonstration of Density Estimation. The color P.c of the point is blended with the color associated with the latest applied function F j:Īfter each iteration, one updates the histogram at the point corresponding to (P.x,P.y).
