BackgroundSubtracter Java class missing "separate" option from Java macro

[George H]

Hi,

I notice there is a parameter missing in the BackgroundSubtracter java
class when I compare it to the recorded macro in Fiji.

The Java macro is IJ.run(imp, "Subtract Background...", "rolling=50 light
separate sliding");

The option "separate" is what I need.

In the BackgroundSubtracter.rollingBallBackground()  there is no parameter
for "separate".

Can someone explain how this is?

Thanks.

Hi George,

for RGB images, the BackgroundSubtracter has two ways to call it:

 - rollingBallBrightnessBackground decomposes the image into hue,
saturation and brightness, and subtracts the background from the
brightness channel only

 - rollingBallBackground(ImageProcessor ip, double radius, boolean
createBackground, boolean lightBackground, boolean useParaboloid, boolean
doPresmooth, boolean correctCorners)
subtracts the background from each color separately. It does what you get
with "separate colors".
