28 * @brief Compute the average RGB color of each partition.
30 * The algorithm here uses a vectorized sequential scan and per-partition
34 * the last partition can be computed given that we know the block-wide average
44 * @param[out] averages The output averages. Unused partition indices will
56 // For 1 partition just use the precomputed mean
61 // For 2 partitions scan results for partition 0, compute partition 1
97 // For 3 partitions scan results for partition 0/1, compute partition 2
144 // For 4 partitions scan results for partition 0/1/2, compute partition 3
