Ask anyone, and you'll probably hear that removing a non-trivial background from a photo is a tough affair. Yet, there is a simpler alternative вЂ“ PhotoScissors. With it, you can get impressive results with merely few mouse gestures.
So, the whole process looks as follows in PhotoScissors:
Load the image you want to strip from its background into the program. Select the green marker and tag areas you want to keep. Select the red marker and mark everything you want to remove. Don't worry too much about accuracy, rough strokes are just fine. Make sure you stay within the silhouette, though.
Enjoy the fine result in just few seconds. However, sometimes you may want to additionally refine the image. Low quality of the source file or complex backgrounds require some additional steps.
The result you receive after automatic processing is usually good enough to stay with it. But there's always room for perfection, right? So let's smooth the edges of the cut out area if they look jagged.
On the side panel at the right of the screen switch to the Foreground tab. You can adjust the Smooth the Boundary parameter from 0 to 10. We set it to 2 to add some anti-aliasing to contours.
Now, the result looks much better:
Nevertheless, there's one more thing we can improve.
As you can see, the contour has become much smoother now, but it still looks unnatural, because tiny fragments of the background are still visible. Happily, PhotoScissors also has the Offset the Boundary option. And that's the tool we need to make our cut out picture look truly perfect.
Offsets can be positive or negative. Negative values shift the contour inward:
While positive ones shift it outward:
To remove residues of the background we need to move the selection contour by 1 pixel inside. So, enter "-1" as the value of the Offset the Boundary option.
The feathering radius controls how many pixels it takes to transition from fully opaque foreground to fully transparent background.
A small radius creates a sharp edge that is suitable for hard objects:
A large radius gives an appearance of softness that works well for certain textiles and other soft or fuzzy objects:
Ok, we are done! And all in all we have spent just few minutes on removing the background from the picture. Now we can save it as a JPG or PNG image. Note, that if you want to retain transparency of the background, you should always select the PNG format.
