Figure 14
(a-i) Image of a binary bee and (b-i) a multiple gray-level bee partially covered with several folded layers of Al tape. The recovered images (a-iii) and (b-iii) compare well relative to the expected images (a-ii) and (b-ii), respectively. The 15 × 15 Huffman-like arrays were created from quaternary masks using pixels with pitch: (a) 10 µm, (b) 20 µm. |
