摘要： Introduced here are computer programs and associated computer-implemented techniques for determining reflectance of an image on a per-pixel basis. More specifically, a characterization module can initially acquire a first data set generated by a multi-channel light source and a second data set generated by a multi-channel image sensor. The first data set may specify the illuminance of each channel of the multi-channel light source (which may be able to produce visible light and/or non-visible light), while the second data set may specify the response of each sensor channel of the multi-channel image sensor (which is configured to capture an image in conjunction with the light). Thus, the characterization module may determine reflectance based on illuminance and sensor response. The characterization module may also be configured to determine illuminance based on reflectance and sensor response, or determine sensor response based on illuminance and reflectance.

摘要： A vehicular vision system includes a plurality of cameras and an ECU. The cameras are in communication with one another via a vehicle network and image data captured by the cameras is provided to the ECU. Responsive to a type of driving maneuver of the vehicle, (i) the ECU generates a first control signal that enables automatic control of exposure, gain and white balance of one camera of the plurality of cameras and (ii) the ECU generates respective second control signals that disable automatic control of exposure, gain and white balance of at least one other camera of the plurality of cameras. Responsive to processing of captured image data, composite video images derived from image data captured by the plurality of cameras are synthesized, and composite images are displayed that provides bird's eye view video images derived from video image data captured by the cameras.

摘要： Disclosed herein is robust detection of facial expressions that accounts for interferences on the face. In one embodiment, a system includes a head-mounted device that comprises (i) light sources configured to emit light towards a first region on a user's face, and (ii) discrete photosensors, spread over more than 2 cm, which take measurements of reflections of the light from the first region. Additionally, the system includes a head-mounted camera that captures images of a second region on the face. A computer calculates, based on the images, an extent of presence of hair over a portion of the first region. Optionally, the computer calculates extents of other interferences such as perspiration, applied makeup, and skin infection. The computer then detects facial expressions of the user based on the measurements of the reflections and the calculated extent of the hair and/or other interferences.
