摘要： Infrared imaging systems and methods disclosed herein, in accordance with one or more embodiments, provide for detecting petroleum in an infrared image. The detection involves the evaluation of local background model likelihoods in light of extracted pixel features as well as the evaluation of a global outlier model in light of extracted pixel features. Those pixels having a low likelihood for both their local background model as well as the outlier model are identified as corresponding to oil-contaminated water within the infrared image.

摘要： Various techniques are disclosed for reducing spatial and temporal noise in captured images. In one example, temporal noise may be filtered while still retaining temporal responsivity in filtered images to allow low contrast temporal events to be captured. Spatial and temporal noise filters may be selectively weighted to more strongly favor filtering using whichever one of the filters is least likely to cause a loss of signal fidelity in actual scene content. Other techniques are disclosed for determining various parameters of imaging systems having image lag. For example, a mean-variance characterization and a noise equivalent irradiance characterization may be performed to determine parameters of the imaging systems. Results of such characterizations may be used to determine the actual performance of the imaging systems without the effects of image lag.

摘要： Various techniques are disclosed for bolometer circuits and related methods for thermal imaging in a difference domain, where each pixel value represents a difference in incident IR radiation intensity between adjacent bolometers. For example, a bolometer circuit may include an array of bolometers each configured to generate a pixel signal in response to a bias and incident infrared radiation. Each column of the bolometer array may comprise an amplifier, a first plurality of switches each configured to selectively provide a supply voltage to a respective one of bolometers of the each column, a second plurality of switches each configured to selectively route a difference of the pixel signals of a respective adjacent pair of the bolometers of the each column to an input of the amplifier, and a third plurality of switches configured to selectively provide a common voltage to a respective one of the bolometers of the each column.

摘要： Systems and methods are disclosed herein to detect pixels exhibiting anomalous behavior in captured image frames. In some examples, temporal anomalous behavior may be identified, such as flickering pixels exhibiting large magnitude changes in pixel values that vary rapidly from frame-to-frame. In some examples, spatial anomalous behavior may be identified, such as pixels exhibiting values that deviate from an expected linear response in comparison with other neighbor pixels.
