We present a new method for detection of the integrated Sachs-Wolfe (ISW)imprints of cosmic superstructures on the cosmic microwave background, based ona matched filtering approach. The expected signal-to-noise ratio for thismethod is comparable to that obtained from the full cross-correlation, andunlike other stacked filtering techniques it is not subject to an a posterioribias. We apply this method to Planck CMB data using voids and superclustersidentified in the CMASS galaxy data from the Sloan Digital Sky Survey DataRelease 12, and measure the ISW amplitude to be $A_\mathrm{ISW}=1.64\pm0.53$relative to the $\Lambda$CDM expectation, corresponding to a $3.1\sigma$detection. In contrast to some previous measurements of the ISW effect ofsuperstructures, our result is in agreement with the $\Lambda$CDM model.
