Abstract EN
A number of acceleration schemes for speeding up the time-consuming bilateral filter have been proposed in the literature.
Among these techniques, the histogram-based bilateral filter trades the flexibility for achieving O(1) computational complexity using box spatial kernel.
A recent study shows that this technique can be leveraged for O(1) bilateral filter with arbitrary spatial and range kernels by linearly combining the results of multiple-box bilateral filters.
However, this method requires many box bilateral filters to obtain sufficient accuracy when approximating the bilateral filter with a large spatial kernel.
In this paper, we propose approximating arbitrary spatial kernel using a fixed number of boxes.
It turns out that the multiple-box spatial kernel can be applied in many O(1) acceleration schemes in addition to the histogram-based one.
Experiments on the application to the histogram-based acceleration are presented in this paper.
Results show that the proposed method has better accuracy in approximating the bilateral filter with Gaussian spatial kernel, compared with the previous histogram-based methods.
Furthermore, the performance of the proposed histogram-based bilateral filter is robust with respect to the parameters of the filter kernel.
