To narrow the inherent sensing gap in heterogeneous face recognition (HFR), recent methods have resorted to generative models and explored the ?recognition via generation? framework. Even though, it remains a very challenging task to synthesize photo-realistic visible faces (VIS) from near-infrared (NIR) images especially when paired training data are unavailable. We present an approach to avert the data misalignment problem and faithfully preserve pose, expression and identity information during cross-spectral face hallucination. At the pixel level, we introduce an unsupervised attention mechanism to warping that is jointly learned with the generator to derive pixel-wise correspondence from unaligned data. At the image level, an auxiliary generator is employed to facilitate the learning of mapping from NIR to VIS domain. At the domain level, we first apply the mutual information constraint to explicitly measure the correlation between domains and thus benefit synthesis. Extensive experiments on three heterogeneous face datasets demonstrate that our approach not only outperforms current state-of-the-art HFR methods but also produce visually appealing results at a high resolution.

Current State

The ternary II-VT alloy Hg1-xCdxTe has become the material of choice for many infrared detector applications. Current state of the art Hg1-xCdxTe infrared focal plane arrays (IRFPAs) are constructed as hybrid structures consisting of an epitaxial sensing layer of Hg1-xCdxTe on either a CdTe or Cd1-xZnxTe substrate, hybridized to a silicon readout circuit chip. For backside illuminated structures, like the typical infrared Hg1-xCdxTe detector array, multilayer antireflective coatings (AR) are required on the backside of the detector chip. The next generation of higher performance IRFPAs will be based on high densities of smaller detector pixels fabricated on large area monolithic heteroepitaxial substrate materials. Since the ultimate performance of photovoltaic diodes of this type is determined by the signal to noise ratio of the device, reducing the size of the pixels while lowering the undesirable noise currents in the devices also reduces the amount of signal generated by the diode.

Fluorescence-enhanced optical imaging using near-infrared (NIR) light developed forin vivomolecular targeting and reporting of cancer provides promising opportunities for diagnostic imaging. The current state of the art of NIR fluorescence-enhanced optical tomography is reviewed in the context of the principle of fluorescence, the different measurement schemes employed, and the mathematical tools established to tomographically reconstruct the fluorescence optical properties in various tissue domains. Finally, we discuss the recent advances in forward modeling and distributed memory parallel computation to provide robust, accurate, and fast fluorescence-enhanced optical tomography.
