    Abstract: Methods and apparatuses for compressive sensing that enable efficient recovery of features in an input signal based on acquiring a few measurements corresponding to the input signal. One method of compressive sensing includes folding an image to generate first and second folds, and recovering a feature of the image based on the first and second folds without reconstructing the image. One example of a compressive sensing apparatus includes a lens, a focal plane array coupled to the lens and configured to generate first and second folds based on the image, and a decoder configured to receive the first and second folds and to recover a feature of the image without reconstructing the image. The feature may be a local geometric feature or a corner. Compressive sensing methods and apparatuses for determining translation and rotation between two images are also disclosed.

  • Publication number: 20140193081
    Abstract: When encoding a set of texture data elements 30 for use in a graphics processing system, the direction along which the data values of the set of texture data elements in question exhibit the greatest variance in the colour space is estimated by using one or more infinite planes 41 to divide the texture data elements in the colour space. For each such plane, texture data element values on each side of the plane are added up to give respective sum points 48, 49, and the vector 50 between these two sum points determined. The direction in the data space of one of the determined vectors 50 is then used to derive endpoint colour values to use when encoding the set of texture data elements.

  • Publication number: 20140193094
    Abstract: Aspects of an edge smoothing block filter and combinations of the filter with a motion compensated temporal filter are described. In one embodiment, edge smoothing block filtering includes selecting a current pixel to be filtered and selecting a candidate pixel within a search area about the current pixel. The edge smoothing block filtering generally seeks to identify candidate pixels having surrounding pixels similar to pixels surrounding the current pixel. The edge smoothing block filtering further computes a cost difference between pixels within a candidate pixel neighborhood and pixels within a current pixel neighborhood, and filters the current pixel based on the cost difference. Aspects of the filters and filter element combinations may preserve edges and textures adaptively based on image content. For example, diagonal or curved image edges may be filtered along edges while texture is preserved along the edges.

    Abstract: Provided is an optical module capable of inhibiting both the displacement of an optical axis caused by thermal changes and property degradation in an optical functional circuit. The optical module includes: a planar lightwave circuit including a waveguide-type optical functional circuit and a waveguide region where only an optical waveguide is formed in contact with a side, wherein an emission end face where output light is emitted from the optical functional circuit, or an entrance end face where input light is entered to the optical functional circuit is formed in contact with the side; a fixing mount employed to hold the planar lightwave circuit only in the portion where the waveguide area is located; and an auxiliary mount employed to hold the planar lightwave circuit in contact with a side that is opposite the side where the emission end face or the entrance end face.

    Abstract: An optical coupler has a waveguide coupled to a grating of multiple scattering units, each scattering unit having a first scattering element formed of a shape in a polysilicon gate layer and a second scattering element formed of a shape in a body silicon layer of a metal-oxide-semiconductor (MOS) integrated circuit (IC). The couplers may be used in a system having a coupler on each of a first and second IC, infrared light being formed into a beam passing between the couplers. Vias may be interposed in third ICs between the first and second ICs. The couplers may be configured with nonuniform width of scattering elements to produce Gaussian or focused beams.

  • Publication number: 20140193118
    Abstract: An optical mover with functions of nanometer fine adjustment and micrometer coarse adjustment is mainly used to align two optical elements for connecting two optical elements, such as connection of two optical fibers, connection of one optical fiber with a photo diode, or connection of one optical fiber and one optical waveguide. In using, one optical element is placed upon the supporting seat for fine position adjustment, and another optical element is fixed on an external retainer for aligning to the former optical element on the supporting seat. A coarse control button is firstly used to coarsely adjust the position of the former optical element to approximately align to the later optical element. Then a fine-adjusting button is used to fine adjust the position therebetween so as to well align the two optical elements to a desire level for further operation, such as connecting the two elements.
