Abstract: A visible light sensor may be configured to sense environmental characteristics of a space using an image of the space. The visible light sensor may be controlled in one or more modes, including a daylight glare sensor mode, a daylighting sensor mode, a color sensor mode, and/or an occupancy/vacancy sensor mode. In the daylight glare sensor mode, the visible light sensor may be configured to decrease or eliminate glare within a space. In the daylighting sensor mode and the color sensor mode, the visible light sensor may be configured to provide a preferred amount of light and color temperature, respectively, within the space. In the occupancy/vacancy sensor mode, the visible light sensor may be configured to detect an occupancy/vacancy condition within the space and adjust one or more control devices according to the occupation or vacancy of the space. The visible light sensor may be configured to protect the privacy of users within the space via software, a removable module, and/or a special sensor.

Abstract: A preprocessing method and a preprocessing system for improving image recognition are provided. The preprocessing method includes the following steps: disposing light-emitting diodes to surround an image sensor, in which the image sensor corresponds to an image capture region; turning on the light-emitting diodes for emitting a white light source having a color temperature of 3200K, in which the white light source has a fixed illumination area range, and the illumination area range covers the image capture region, such that a color temperature of the image capture region is approximately or equal to 3200K; and turning off the light-emitting diodes for a time interval, such that the image sensor captures images to generate preprocessing frames under a low illuminance condition that is between 0.0004 lux and 1 lux.

Abstract: The present disclosure relates generally to evaluating the surfaces of a building. The present disclosure relates more particularly to a method of characterizing a surface texture of a building surface. The method includes illuminating a first area of the building surface from a single direction and capturing an image of the first area using a camera while the first area is illuminated. The first image includes a first group of digital pixel values. The method further includes calculating a first set of values that characterize a first surface texture of the first area based on a first group of digital pixel values of the image, and comparing the first set of values to a second set of values that characterize a second surface texture, so as to produce a comparator value.

Abstract: Disclosed herein systems and methods of performing spoof resistant object recognition. In certain embodiments, a system for object recognition includes: an illumination device configured to illuminate an object; a sensor device, wherein the sensor device receives illumination light reflected off the object which includes polarization information; a processor; memory including programming executable by the processor to: calculate the polarization information from the illumination light; use the polarization information to determine whether the object is a real 3D object. It has been discovered that polarization information may be utilized to determine whether an object is a 3D object or a flat (2D) object. Thus, the polarization information may be utilized to differentiate from an image of a 3D object and a photograph of an object.

Abstract: Some embodiments described herein relate to a method that includes separating an analyte-containing sample via electrophoresis in a capillary. The capillary is loaded with a chemiluminescence agent, such as luminol, that is configured to react with the analyte (e.g., HRP-conjugated proteins) to produce a signal indicative of a concentration and/or quantity of analyte at each location along the length of the capillary. A first image of the capillary containing the analytes and the chemiluminescence agent is captured over a first period of time. A second image of the capillary containing the analytes and the chemiluminescence agent is captured over a second, longer, period of time. A concentration and/or quantity of a first population of analytes at a first location is determined using the first image, and a concentration and/or quantity of a second population of analytes at a second location is determined using the second image.

Abstract: Embodiments described herein involve determining an area of interest on a growth media. An overall brightness control value for a plurality of illumination sources configured to illuminate the growth media is calculated. The overall brightness control value generating at least one image that substantially matches a target intensity at the area of interest. An individual brightness value for each illumination source of the plurality of illumination sources is calculated by individually adjusting a brightness of each illumination source to generate at least one image that substantially matches the target intensity in each respective illumination source's area of influence. A calibrated brightness value for each illumination source is determined based on an image intensity with each illumination source turned on at the respective individual brightness value and an intensity that each illumination source generates within each respective area of influence when turned on alone.
