Abstract: A mobile computing device that includes an image sensor may be used to detect the result of a biomolecular assay. The biomolecular assay may be performed in an optical assay medium that provides an optical output in response to light from a light source, with the optical output indicating result. A wavelength-dispersive element may be used to disperse the optical output into spatially-separated wavelength components. The mobile computing device may be positioned relative to the wavelength-dispersive element such that different wavelength components are received at different locations on the image sensor. With the mobile computing device positioned in this way, the image sensor may be used to obtain one or more images that include the separated wavelength components of the optical output. A wavelength spectrum of the optical output may be determined from the one or more images, and the result may be determined from the wavelength spectrum.

Abstract: An Advanced Laser Fluorometer (ALF) can combine spectrally and temporally resolved measurements of laser-stimulated emission (LSE) for characterization of dissolved and particulate matter, including fluorescence constituents, in liquids. Spectral deconvolution (SDC) analysis of LSE spectral measurements can accurately retrieve information about individual fluorescent bands, such as can be attributed to chlorophyll-a (Chl-a), phycobiliprotein (PBP) pigments, or chromophoric dissolved organic matter (CDOM), among others. Improved physiological assessments of photosynthesizing organisms can use SDC analysis and temporal LSE measurements to assess variable fluorescence corrected for SDC-retrieved background fluorescence. Fluorescence assessments of Chl-a concentration based on LSE spectral measurements can be improved using photo-physiological information from temporal measurements. Quantitative assessments of PBP pigments, CDOM, and other fluorescent constituents, as well as basic structural characterizations of photosynthesizing populations, can be performed using SDC analysis of LSE spectral measurements.

Abstract: Embodiments of the invention relate to the determination of the color of a color sample from an image of the color sample. In one embodiment a color sample capture card is provided having printed thereon color samples of known color (for example, XYZ tri-stimulus values). An image of the test color sample is then captured using domestically available equipment, such as a consumer digital camera or camera-equipped mobile telephone, the image also containing the color sample capture card. In one embodiment the image is then transmitted to a remote color determination service for color sample color determination. Regression analysis is then performed using the RGB color samples in the image and known XYZ colors thereof to characterize the color capture response of the image capture device. Having characterized the image capture device the XYZ color of the unknown color sample can be determined from the RGB color thereof in the image. Knowing the XYZ color, the color can then be matched to a palette of paint colors, to determine a paint color to match the unknown color.

Abstract: What is disclosed is a system and method for real-time enhancement of an identified time-series signal of interest in a video that has a similar spatial and temporal structure to a given reference signal, as determined by a measure of closeness. A closeness measure is computed for pixels of each image frame of each channel of a multi-channel video to identify a time-series signal of interest. The intensity of pixels associated with that time-series signal is modified based on a product of the closeness measure and the reference signal scaled by an amplification factor. The modified pixel intensity values are provided back into the source video to generate a reconstructed video such that, upon playback of the reconstructed video, viewers thereof can visually examine the amplified time-series signal, see how it is distributed and how it propagates. The methods disclosed find their uses in remote sensing applications such as telemedicine.

Abstract: A video image capture component includes a light source operable in a first spectrum, a first image detector operable in the first spectrum, a second light source operable in a second spectrum, and a second image detector operable in the second spectrum. A filtering component generates a combination image by filtering a first image obtained by the first image detector with a high-contrast filter, resulting in a high-contrast image, and masking a second image obtained by the second image detector using the high-contrast image. A compositing component creates a composite image from the combination image and a selected image. A display component displays the composite image.Alternative systems and methods for creating a combination image include techniques involving thermal imaging, laser detection, and narrow band frequency detection.

Abstract: An imaging section that detects the amount of light separated by a wavelength tunable interference filter to acquire a spectroscopic image (imaging device and light amount acquisition section) detects the amount of light successively separated for three wavelengths to acquire spectroscopic images for producing a combined image. A display controller causes a display section to display a combined image based on the spectroscopic images for producing the combined image. A specified position detection section identifies based on user's operation a specified position where a colorimetry result is to be outputted. The imaging section detects the amount of light successively separated for a plurality of wavelengths by the wavelength tunable interference filter to acquire spectroscopic images for colorimetry corresponding to the plurality of wavelengths. A colorimetry section measures the color in the specified position by using the amount of light obtained from each of the spectroscopic images for colorimetry.
