@nosle gave permission to use his pixelshift files
For that reason I want to open a pixelshift competition using one of his very good example files:
What is this contest about?
- Show the best result you can get out of this file while correcting as much motion as possible and preserving as much detail as possible using pixelshift with or without motion correction.
- Starting point is the rt default profile (not the neutral profile)
- Then go to raw tab, select pixelshift and make changes only to pixelshift settings.
No other changes to settings in rt please.
results of other software which supports pixelshift are welcome to compare (acr, silkypix, pdcu...)
Here's my approach which also is intended to be a short tutorial:
Have a look at the details to preserve: left is amaze right is pixelshift without motion correction:
Have a look to the reduced noise: left is amaze right is pixelshift without motion correction:
But there's a van moving through the images:
And also some other motion in the trees:
Let's have a look at the motion mask (one of the most important things):
All pixels marked green will be taken from the amaze demosaiced frame of your choice while the other pixels will be rendered in pixelshift resolution.
Now we know where the motion is, let's have a look what simple (but very important) green motion detection does:
There are some visible artifacts because green detection wasn't able to dectect all motion. Let's have activate
red/blue cross and check again:
Number of artifacts is reduced but there are are sill some of them. Let's have a look at the current motion mask again:
As you can see there are
holes in the motion mask. In this holes motion is not corrected. Let's fill the holes and look at the motion mask:
And take a look without the motion mask:
In next play pixelshift game I will also explain the smooth transitions stuff but for now I would be glad to get competitions
