Web6 jun. 2024 · For each of these classes, the CIE specified a standard reflection table (r-table), containing the reduced luminance coefficients. Note that those tables do not correspond to real road surfaces. For each standard R-class, the average luminance coefficient (the so-called normalised average luminance coefficient, Q 0 normal.) was … WebFuv, the upper-left coefficient F00 is 8 times the average value of all pixel data within the 8x8 pixel block and is called the DC coefficient. The remaining 63 coefficients are called AC …
