摘要： In general, techniques are described for encoding parameters with unit sum. In one example, an apparatus comprising a control unit implements these parameter encoding techniques. The control unit determines parameters that sum to a constant or unit sum. The control unit includes a parameter coding unit that segments a space that contains the plurality of parameters into a set of portions. The parameter coding unit assigns a different one of a plurality of codewords to each of the portions, selects one of the set of portions that contains a point defined by the plurality of parameters, and codes the plurality of parameters using one of the plurality of codewords assigned to the selected one of the plurality of portions. Rather than code only a subset of these parameters, the parameter coding unit codes all of the parameters with the result of potentially reducing quantization error.

摘要： Techniques are disclosed for performing robust feature matching for visual search. An apparatus comprising an interface and a feature matching unit may implement these techniques. The interface receives a query feature descriptor. The feature matching unit then computes a distance between a query feature descriptor and reference feature descriptors and determines a first group of the computed distances and a second group of the computed distances in accordance with a clustering algorithm, where this second group of computed distances comprises two or more of the computed distances. The feature matching unit then determines whether the query feature descriptor matches one of the reference feature descriptors associated with a smallest one of the computed distances based on the determined first group and second group of the computed distances.

摘要： In one example, an apparatus includes a processor configured to extract a first set of one or more keypoints from a first set of blurred images of a first octave of a received image, calculate a first set of one or more descriptors for the first set of keypoints, receive a confidence value for a result produced by querying a feature descriptor database with the first set of descriptors, wherein the result comprises information describing an identity of an object in the received image, and extract a second set of one or more keypoints from a second set of blurred images of a second octave of the received image when the confidence value does not exceed a confidence threshold. In this manner, the processor may perform incremental feature descriptor extraction, which may improve computational efficiency of object recognition in digital images.

摘要： The present disclosure provides systems, methods and apparatus for producing holographic displays using an electromechanical systems device. In one aspect, the method can be implemented to allow for simultaneous modulation of phase and amplitude of light in a display device composed of a plurality of pixels. A light source (150) can provide sufficiently coherent light to a light guide (170), which can direct the light to a plurality of reflective members (112, 114). The reflective members can reflect the light to a pinhole - lenslet array (190). The combination of the pinhole - lenslet array (190) and the reflective members (112, 114) can act as a spatial light modulator, modulating the phase and amplitude of the light reflected by the reflective members. The lenslet (192) can focus the light to a plane at the opening of the pinhole (194), wherein the light can exit the pinhole to be viewed in combination with light from additional pixels, and can be viewed as a holographic image.

摘要： This disclosure provides systems, methods, and devices for actuating, charging and calibrating the charge on a movable electrode in an interferometric device. The interferometric device (1000) can include a first electrode (1002), a second electrode (1010) spaced apart from the first electrode by a gap, at least one electrical contact (2132), and an electrically neutral movable third electrode (1006) disposed between the first electrode and the second electrode. The third electrode can be charged by applying a charging actuation voltage across the first electrode and the second electrode to produce an electric field in the gap. Under the electric field, the electrically neutral third electrode (1006) can move towards the first electrode from a first position to a second position where it connects with the electrical contact (2132). Once in contact with the electrical contact, an electric charge on the third electrode can be changed when the third electrode is in the second position. When a mechanical restorative force on the third electrode exceeds the force of the electric field on the third electrode, the third electrode moves to a third position.

摘要： This disclosure describes the use of non-dyadic discrete cosine transform (DCT) sizes for performing a DCT. Similarly, this disclosure describes the use of non-dyadic inverse discrete cosine transform (IDCT) sizes for performing an IDCT. Using non-dyadic transform sizes may be less computationally expensive compared to using conventional dyadic transform sizes. Aspects of this disclosure may be useful in any device or system that performs a DCT or IDCT.
