The bias attribute shifts the range of the filter. After applying the kernelMatrix of the <feconvolvematrix> element to the input image to yield a number and applied the divisor attribute, the bias attribute is added to each component. This allows representation of values that would otherwise be clamped to 0 or 1.
If bias is not specified, then the effect is as if a value of 0 were specified.
