Split spectrum processing
WebUnder these conditions, a classical Split Spectrum Processing (SSP) algorithm is not optimal to detect all porosities. Our method is a modified SSP algorithm with a variable … WebThe p660 form absorbs red light and is converted to the p73o form believed to induce a biological response. The P 7 3 0 form absorbs far-red and is converted to the inactive P 6 6 0 form. The P 7 3 0 form kept in the dark reverts to the P 6 6 0 form (Hendricks 1959). The action spectrum for photolability is seen in the lower part of Figure 9.
