Note

In the example above: the multiply filter is run in serial mode. This is because one of the sub-filter or sub-filters ('accumulated' in this case) can only be run in serial mode.

If you have a webcam handy or it is built into the laptop, try this command:

Code Block
cv-cat --camera "subtract=accumulated:average,10;view;null"



Add:

This is a wrapper to cv::add

...

Code Block
cat images.bin| cv-cat "add=accumulated:average,3;view=250;null"

This is the result:

Of course you can always try this pipeline with a physical camera:

Code Block
cv-cat --camera "subtract=accumulated:average,10;view;null"

 

Divide:

This filter wraps cv::divide, divides the input images by the operand.
