Detailed Description
template<typename T>
class pcl::io::MedianBuffer< T >
A buffer that computes running window median of the data inserted.
The buffer and window sizes are specified at construction time. The buffer size defines the number of elements in each data chunk that is inserted in the buffer. The window size is the number of last data chunks that are considered for median computation. The median is computed separately for 1st, 2nd, etc. element in data chunks.
The data can contain invalid elements. For integral types zeros are assumed to be invalid elements, whereas for floating-point types it is quiet NaN. Invalid elements are ignored when computing median.
The buffer is thread-safe.

Access an element at a given index.
This operation is constant time.
Implements pcl::io::Buffer< T >.

Insert a new chunk of data into the buffer.
This operation is linear in buffer size and window size.
