Watermark Master provides ability to remove
static objects from a video frame or graphics file. This
operation is performed similarly to adding
a watermark.
To remove a static object from an image, click
? button on the
Watermark
toolbar or open menu Watermark > Add > Eraser - a transparent
rectangle will appear in the preview area of the main program window.
Click and drag the rectangle on the object to be removed. Click and drag
the rectangle borders to make the rectangle fit the object.
After an Eraser watermark is added, its properties
become available in the "Properties" window.
Main
This section includes the main properties
of the Eraser watermark.
Width - the width
(in pixels).
Height - the height
(in pixels).
Options.
This section includes optional
properties of the Eraser watermark.
Mask - the type of the static object
search. This parameter can take one of the following values:
Preprocessing
- this search type is applicable to video source files only. If selected,
the source video will be preprocessed, which will allow to precisely determine
the mask (static object's contour). In this case the following parameter
become available:
Time Cell - the mask search range.
This parameter can take one of the following values:
All
Video - if selected, the mask will be searched throughout the whole video
file.
Custom
Time - if selected, the mask will be searched throughout the specified
time interval. In this case the following parameter becomes available:
Time - the time (from the beginning
of the source video) that the preprocessing will take (in hh:mm:ss.ms
format, where hh - hours, mm - minutes, ss - seconds, ms - milliseconds).
Color
- if selected, the mask will be based on the specified color. This parameter
is recommended for use when the unwanted static object is (almost) monochromatic.
Color - the color the mask will be
based on. Click "..." button on the right of the "Color"
caption to select the required color. Besides, you can select the color
with the help of the Eyedropper tool. For that click button
on the Watermark
toolbar (or press "CTRL + P") and pick the required color
directly from the image.
Tolerance - defines the range of colors
for the mask. This parameter can take values from 0 to 255. A low value
selects the few colors very similar to the color selected above. A higher
value selects a broader range of colors.
No
mask - if selected, no mask will be used. All objects covered by the Eraser
watermark will be removed. This type is especially effective when the
static object is small.
