      Such symmetric quincunx tight framelets are associated with quincunx tight framelet filter banks having increasing orders of vanishing moments and enjoying the additional double canonical properties: For a low-pass filter which is not a quincunx orthonormal wavelet filter, we show that a quincunx tight framelet filter bank with taking the above canonical form must have high-pass filters.
