Scratch Remover offers the quickest answer to texture repair and defect removal in Image Doctor. Scratch Remover is a simpler-to-use counterpart to the more elaborate Smart Fill filter, and should be used to clean up minor texture defects placed in fairly homogenous surrounding textures. Use it primarily for eliminating linear defects such as tears and creases or to remove small text, such as time stamps, subtitles, or logo text from images. Scratch Remover samples textures from areas surrounding your selection and recombines them inside your selection to organically repair images. This avoids the repetitive patterns that result from directly cloning source textures. Before After This chapter contains the following sections: Using Scratch RemoverTo use Scratch Remover:
Slider DescriptionsContract or Expand Selection (pixels)Use this slider to
contract or expand your original selection from within the Image Doctor
interface. Why? If the initial preview reveals remnants of your original selection, you can expand your selection to knock out the leftovers. If you find that you are removing some nearby desirable image detail, you can contract your selection a couple of pixels to protect that area. Its best to make a good, close selection before you run the filter, however. Texture Feature SizeUse this slider to
specify the texture sample size that Scratch Remover uses for texture
replacement. If, for example, the blades of grass that make up the sampled
texture are roughly 15 pixels tall, pump up the feature size to about
15 pixels. Texture RegularityThese radio buttons
control how closely Scratch Remover matches the image details generated
in your selection. For more predictable textures, such as bricks, use
higher values. For irregular patterns, such as grass, sometimes lower
values will do just fine. Using lower Texture Regularity values helps
the filter render faster and randomizes the appearance of image details
generated in your selection. Feather RadiusFeather Radius creates
an opacity drop off around the edge of the affected area of your imagehelping
blend the filtered area with the surrounding unaffected pixels.
Regenerate TextureUse this button to randomly rearrange the fill details generated by Scratch Remover. In many cases, you can simply run the Scratch Remover filter, click Regenerate Texture a few times, and get great results. TutorialsRemoving Time Codes from Photos or Video CapturesRemoving time codes from photos and video captures is a snap with Image Doctor. We suggest that you use the following steps to obtain the best results.
1. Use the magic wand
tool to select a single character at a time. 2. Run Scratch Remover.
3. Adjust the Contract/Expand
Selection slider until all traces of the character have been affected. 4. Use the Texture
Feature Size, Regenerate Texture button, and Feather Radius slider until
you are satisfied with the background replacement. 5. Click OK. 6. Using the magic
wand, select the next character. 8. Repeat Steps 5 and 6 until you have completely removed the time code. Note: Keep
an eye on your results. Generally, the first attempt works just fine;
occasionally, however, you may need to open the filter interface and tweak
the sliders to completely remove a character. Heres your result. Tips and Tricks
