Blend: Sets the % of the original image to be feathered at the edges of the repair.
Optimize: Turning this option on provides better-looking results, at the expense of
increased processing time.
ROI Mode: Determines whether a correction is applied with a single click, or via
a paint stroke. There are three options.
Click and Clean: Applies a correction with one click, and is fast to use on small
dust spots.
Draw and Clean: Lets you “paint” over a larger dirty area with the mouse or a pen,
with the correction being applied at the conclusion of your paint stroke.
CNC Size: Defines the width of the “brush” that’s used to paint out dirt and dust.
Algorithms for Dirt and Dust Removal
There are six algorithms you can choose from that determine how the pixels you paint over are
automatically replaced.
Auto-temporal –/+ 1: When an ROI is drawn, the previous frame, the next frame and
the current frame will all be used for analysis. The best of these 3 will be automatically
selected and used for removing the dirt in the current frame.
Auto-temporal –/+ 2: This is the same as the above, but the frames used instead are
the current frame, previous-to-previous frame (i.e., 2 frames back), and next-to-next
frame (i.e., 2 frames forward). Therefore, if the ROI is drawn on frame 100, frame 98,
frame 100, and frame 102 will be used for analysis. The best of these 3 will be used
for removing the dirt in the current frame. The advantage of this selection is that it will
avoid the appearance of frozen grain, which may be possible in case of dirt against a
stationary background.
Temporal –/+ 1: if the ROI is drawn by dragging the mouse from left to right, the
next frame will be used for motion-compensated dirt removal. If the ROI is drawn by
dragging the mouse from right to left, the previous frame will be used.
Temporal –/+ 2: if the ROI is drawn by dragging the mouse from left to right, the
next-to-next frame will be used for motion-compensated dirt removal. If the ROI
is drawn by dragging the mouse from right to left, the previous-to-previous frame
will be used.
Spatial: In case of fast or blurred motion, using the previous or next frames may give
unsatisfactory results. In this case, the same frame itself can be used for removing the
dirt. This will use surrounding information in the current frame to remove the dirt.
Median: The Median filter performs a blending of the pixels, smoothing out the
region. Use this when other options do not replace the image, or when there is no
support information in which to reconstruct the original. Using small boxes will produce
better results.
