Abstract: This invention presents an approach to first estimate a depth/disparity map using spectrally coded plenoptic camera, and then based on the disparity map the parallax between different spectral channels is rectified. Based on our new technique, we can reconstruct not only multispectral images but also a depth/disparity map. Moreover, the quality of reconstructed spectral images is significantly improved using our parallax rectification.

Abstract: An adjustable multimode lightfield imaging system. A non-homogeneous filter module is positioned at the pupil plane of the lightfield imaging system and provides the multimode capability. The filter module can be moved relative to the imaging system with the exposure conditions adjusted accordingly, thus allowing adjustment of the multimode capability.

Abstract: Passive RFID devices are disclosed that perform image recognition. The device includes an antenna, circuitry, and a camera. The antenna receives a radio frequency (RF) signal from a RFID reader. The circuitry stores image data for objects that is used for image recognition. To operate, the circuitry derives power from the RF signal. With the power derived from the RF signal, the camera captures an image. The circuitry then identifies an object in the captured image based on the image data for the objects, and outputs information for the identified object, such as to the RFID reader.

Abstract: Calibration for plenoptic imaging systems. The calibration preferably is performed automatically by a processor. In one approach, the processor accesses a plenoptic image captured by the plenoptic imaging system. The plenoptic image is analyzed to determine reference points for superpixels of the plenoptic imaging system, for example the centers of the superpixels. The reference points are used to determine a location of each superpixel relative to the detector array.

Abstract: The spatial resolution of captured plenoptic images is enhanced. In one aspect, the plenoptic imaging process is modeled by a pupil image function (PIF), and a PIF inversion process is applied to the captured plenoptic image to produce a better resolution estimate of the object.

Abstract: The pupil image function (PIF) matrix of a plenoptic imaging system is calibrated, taking advantage of the low rank of the PIF matrix. In one approach, the low rank is utilized by identifying a subspace for the PIF matrix and then estimating the PIF matrix within that subspace. This can lead to a significant reduction in the number of calibration patterns used to estimate the PIF matrix.

Abstract: A three-dimensional scene is modeled as a set of layers representing different depths of the scene, and as masks representing occlusions of layers by other layers. The layers are represented as linear combinations of atoms selected from an overcomplete dictionary. An iterative approach is used to alternately estimate the atom coefficients for layers from a light field image of the scene, assuming values for the masks, and to estimate the masks given the estimated layers. In one approach, the atoms in the dictionary are ridgelets oriented at different angles, where there is a correspondence between depth and angle.

Abstract: Light field images of a three-dimensional scene are transformed from an (image,view) domain to an (image,scale,depth) domain. Processing then occurs in the (image,scale,depth) domain.

Abstract: Color plenoptic images captured by a spectrally-coded plenoptic imaging system are combined with higher resolution higher resolution images captured by a conventional imaging system, resulting in color images with higher resolution than those captured by the plenoptic imaging system alone.
