The circular symmetricpoint and the apalanatic point of spherical lens have one same expression, however the two kinds conjugate point are belong to difference category.
Moreover, all symmetric and antisymmetric wavelets, which have same symmetricpoint as the scaling function and the length of their filters are no more than 8, are also given.
