[Insight-users] HoughTransform2DImage Filter question

[Tatyana Ivanovskaya]

Dear All!
I have a newbie question:
I want to take a look at the accumulator image, so i want to output it
somehow.
In the example HoughTransform2DCirclesImageFilter.cxx :

AccumulatorImageType:: Pointer localAccumulator = houghFilter->getOutput();

How can one output the accumulator values to a file or to grayscale image?
I mean, how to operate with the localAccumulator?

Thank you in advance.
Tanya
