Image quality evaluation standard of information hiding algorithm mainly relied on the traditional standard such as peak signal to noise ratio (PSNR), but PSNR does not meet people's subjective assessment. So it is necessary to set up the objective evaluation criteria with subjective uniformity for information hiding algorithm. In this paper, an image subjective quality evaluation model is proposed...
We report a highly simplified single-mesa organic/inorganic hybrid near-infrared-to-visible imaging upconversion device (spatial resolution ∼10 μm). This device integrates an intrinsic-InGaAs substrate and an organic light emitting diode.
We report an organic/inorganic hybrid optical amplifier with a function of converting infrared light to visible light. This device integrates an InGaAs/InP heterojunction phototransistor (HPT) and an organic light emitting device.
We report a near-infrared to visible-light optical upconverter by the integration of an i-In0.53Ga0.47As/C60 junction and organic light emitting diode. This device shows the photovoltaic effect of i-In0.53Ga0.47As/C60 junction and application in optical upconverter.
