WebThe box filter is separable, so to perform a 2D box filter we perform the filter in: the x direction, followed by the same filter in the y direction. Applying multiple iterations of the box filter converges towards a Gaussian blur. … WebThe constant value of weight is 1 / (2 ⋅ br)2 (so the sum over the whole weight is 1). We can define box blur as: bb[i, j] = i + br ∑ y = i − brj + br ∑ x = j − brf[y, x] / (2 ⋅ br)2. We have to convert the standard deviation of gaussian blur r into dimensions of boxes for box blur.
