Fig. 4: The construction of adaptive texture camouflage.
From: Light-programmable mechanical computing via polyaniline composite film
a Process of texture camouflage: the optical information is sensed by single-pole single-throw (SPST) relays (i) within the sensing-computation-emission (SCE) unit (ii) and subsequently processed through an AND logic operation to generate control signals that drive a 3 × 3 light bulb array (iii). (P1, P2, and P3) are the optical input signals, and the corresponding optical output signals are (Q11, Q12, …, Q33). b Evaluation of texture reconstruction: original input images (i–iv) and corresponding camouflage patterns (v–viii) generated by the computing circuit, demonstrating accurate replication of brightness gradients. c Realistic scenario demonstrating adaptive texture camouflage in underwater environments with corals (i), rocks (ii), and sand (iii), and simulated camouflage patterns (iv–vi) generated by the SCE unit. Scale bar: 3000 pixels (i–iii); Scale bar: 600 pixels (iv–vi). MATLAB was used to perform simulations of the adaptive texture camouflage results.
