Removing Large Objects
AKVIS Retoucher offers two types of processing for photographs: retouching (eliminating defects and scratches) and removing objects. The sequence of actions involved in both cases is different: retouching is mainly performed through automatic processing, while when removing large objects, part of the work is done manually and requires learning how to use the Linear Retouch and Patch tools.
The following are general suggestions for removing a large object. At any stage you can undo changes with the / buttons, make adjustments and then process the image again.
- Step 1. Open the image in AKVIS Retoucher, and switch to Advanced mode.

- Step 2. Select the object which you want to remove (along with any shadows or reflections).
Selecting the Object
- Step 3. Use the Linear Retouch tool to restore the main lines of the background through the image. Linear Retouch allows you to restore the background in a specified direction: for example, to align the junction of areas or preserve the smooth edges of an object. It is also useful for breaking a large object into smaller pieces, making it easier to remove.
Direction of Lines
Draw lines as long as possible, through the red zone and beyond it. Once a line is drawn, the fragments along it are immediately restored:

- Step 4. Use the Patch to fill in the red zone with samples from the image which are the best suited for restoring the background.

Placing more patches in heterogeneous areas produces a better result, such as for an area covered in grass. Fewer samples would need to be placed in a homogeneous area, such as the sky.
Filling with Patches
It's better to use the Linear Retouch tool over the walkway, since it has a pronounced banded pattern.

The area around the path now looks like this:

- Step 5. Use the Linear Retouch to connect all patches and divide the selection into homogeneous fragments. You can draw small lines through fragments.
- Step 6. Use Local Run to restore individual fragments, starting with those at the edges of the object to be removed. Processing is started by clicking on a fragment. Parameters for each selection can be adjusted in the Settings Panel.
Why process the selection in fragments? When full processing (with the button) is applied, all of the fragments are processed at the same time. It's a long process in which samples are taken from areas adjacent to the selection, so they may not be best suited for properly restoring the entire selection. Therefore, areas processed in this manner will tend to appear rougher.
When you use the Local Run tool, samples are taken not only from the original background but also from newly restored areas adjacent to the fragment, allowing the background to be restored more gradually and accurately. Each fragment can be processed selection by selection. Therefore, the overall result depends on the order in which selections are processed.
Processing Selection by Selection
If a fragment was processed unsucessfully, press the button and readjust the settings (or add more patches). If it is difficult to find suitable parts of the background for patches, you can select from restored areas.
This is the result after all areas have been processed.
After Using Local Run
- Step 7. Perform post-processing on the image, to remove seams and other irregularities in restored areas. This can easily be done with the Clone Stamp and Chameleon Brush (which are available in the Home Deluxe and Business versions of the program).
If your version does not have these tools, you can select any remaining defects as done in previous steps and process the image again.
Now the figures have been removed from the picture.
- Step 8. Save the resulting image.
