Photo Crop Editor is an Interactive Photo Editor software for selecting and
removing an object in a picture or photograph from its background. The user
can then compose the result on a different background to create a new scene.
Interactive Photo Editor works even if foreground and background colors are
similar.
Interactive Photo Editor consisting of three steps:
1. Object marking:
In this first, coarse step the user quickly identifies the object of interest by marking quick mouse strokes, using
left-click for foreground and right-click for background. The software will lookup object boundary automatically.
2. Boundary editing:
In the editing step, the user can edit a boundary directly.
3. Bayesian matting step:
In this step, it is easy to matte hair from background.
4. The final step extracts the cut out object and compose it onto new background.
Start Tutorial
Step1: Segmentation
Step2:
Editing Step3:
Overriding Brush
Step4: Matting Step5:
Output Composition
Step6: Save and Print
Step7: Perform Better
Step1:
Segmentation
-
Press and hold the right button of mouse, draws a few
strokes on the background in image. When the mouse button is released,
the interactive image segmentation engine is started, and a boundary of
foreground is generated by program. The program interface shows as
following:
Step2: Editing
-
Select the polygon button on tool bar, and then use
mouse to draw a polygon which surrounds the eye part on image, the eye
part will be added to the current selection. The program shows as
following.
Usage of polygon tool is "Click left button =>
move cursor=> click left button => move cursor=> click left
button......, then, double click left button, the polygon is finished".
-
Select the "Subtract from selection" button on tool bar,
then use mouse to draw a polygon which surrounds the small white spot on
left side of image, the small white spot will be subtract from the
selection:
Step3: Overriding Brush
-
Select the overriding brush button on tool bar, and then
use mouse to draw a polyline to replace the jaggy segment of the
boundary as following.
Usage of overriding brush tool is same as polygon
tool: "Click left button => move cursor=> click left button => move
cursor=> click left button......, then, double click left button, the
polyline is finished, and the jaggy segment of the boundary is replaced
by the polyline".
Please make sure that the polyline should
intersect with the boundary at at least two points,
the segment between the two outside crosspoints
will be replaced by the polyline.
Step4: Matting
-
When the mouse button is released, the Bayesian matting
engine is started, all alpha value of pixels within the unknown region
will be computed. This function is very useful for matting hair from
background.
-
The Bayesian matting engine has made some part of
background become foreground. To correct this, click "Back to editing
step" button to go back to "Editing step", and then subtract the part of
background from the selection.
Step5: Output Composition
-
Select "Background->Background Picture" to compose the
foreground onto other picture, shows as following, or select
"Background->Background Color" to compose the foreground onto other
color background:
Step6: Save and Print
-
Click "Save" or "Print" button, the "Image Output"
dialog appears. Move cursor onto handles of the selected rectangle, then
drag mouse while holding left button to resize the selected rectangle.
Then click "Save" or "Print" button to save or print image within the
selection:
Step7:
Perform Better
-
The interactive image segmentation engine can perform
better when marking foreground and background by surrounding foreground
and background with polygons.
-
Select the polygon button on tool bar. Use mouse left
button to draw a polygon along the edge of the foreground.
Usage of polygon tool is "Click left button =>
move cursor=> click left button => move cursor=> click left
button......, then, double click left button, the polygon is finished".
