Robust recognition of low-contrast targets. a Schematic of an intelligent machine vision system integrating tunable-sensitivity phototransistor arrays or conventional sensor arrays with an ANN. The tunable-sensitivity phototransistor enables precise extraction of low-contrast targets. b Imaging comparison using conventional phototransistor arrays and tunable-sensitivity phototransistor arrays. c Recognition accuracy of tunable-sensitivity phototransistors and conventional phototransistors after 100 training epochs at different average contrast conditions. d Tunable-sensitivity phototransistors exhibit high robustness in recognition under salt-and-pepper noise interference
