We propose a two-level dimmer based on binary distribution matching where a low-rate signal controls the output probability distribution of a high-rate bit sequence. which can be used in region-of-interest (RoI) signaling applications. To reduce the rate loss of the dimmer. we propose the extended multiset-partition distribution matching (EMPDM) algorithm with a novel binary-tree-stru... https://cosmeticsolutioners.shop/product-category/hair-color-touch-up/
