HDR - 8

FINALLY !!!

HDR - 7

Here is better result by using 3 different response curve (red, green & blue) at the same time.

1. Linear tone mapping in log domain :

2. Tone mapping in gradient domain :

3. Response curve :

p.s.

In sampling step, I sort all pixels in the image with largest exposure. Force sampling the brightest pixel, then sampling the others averagely.

Never thought that "code" would appear in games !

HDR - 6

alpha = 0.09

beta = 0.9

s = 0.1

HDR - 5

Some bugs are fixed. Here is new radiance map :

linear tone mapped in log domain :

Gradient attenuation map :

linear mapping after attenuation in log domain :

LDR with exp(I) :

Final result :

There are still some problems :

1. How to get better result from Poisson equation ?

2. How to select alpha & beta ?

3. Final result is not as good as the one presented in original paper.

HDR - 4

I think ...... I didn`t add any special effect ......
