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： 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.

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： This disclosure provides systems, methods, and devices for actuating, charging and calibrating the charge on a movable electrode in interferometric devices. The interferometric device can include a first electrode (1002), a second electrode (1010) spaced apart from the first electrode by a gap, a complementary electrode, at least one electrical contact (2132), and a movable third electrode (1006) disposed between the first electrode and the second electrode. In one implementation, a method of calibrating charge on the movable electrode of the EMS device includes electrically connecting a complementary electrode to the first electrode to form a compound electrode and applying a calibration voltage across the compound electrode and the second electrode to produce a uniform electric field in the gap. Under the electric field the third electrode moves towards the first electrode until it connects with the at least one electrical contact. Once in contact with the electrical contact, an electrical charge on the third electrode can be changed and calibrated when the third electrode is in a second position. When a mechanical restorative force on the third electrode exceeds the electric force of the uniform electric field on the third electrode, the third electrode then moves to a third position.

摘要： This disclosure provides systems, methods and apparatus for providing white light color output from an electromechanical systems (EMS) device with reduced likelihood of stiction. In one aspect, interferometric modulators are configured to provide a white color output while having a non-zero modulator gap dimension. Such a feature can reduce problems associated with zero modulator gap dimensions such as stiction. Various methodologies can be used to yield such a non-zero modulator gap and a white color output. In some implementations, for example, an optical element that introduced wavelength dependent phase shift is used. In some implementations this wavelength dependent phase shifting optical element includes a stack of color filters, a hologram, a diffraction grating, or layers of material having specific thicknesses and wavelength dependent indices of refraction.
