Abstract
In the following, we give the complete solutions of all bivariate symmetric orthonormal scaling functions with filter size up to 6 X 6 using the standard dilation matrix 2I as well as construct a set of associated wavelets. In addition, we give two families of refinable functions which are not orthonormal, but upon using the same completion technique appear to form tight frames (i.e. they preserve the norm) at least experimentally.
