Assignee:

nLine Corporation - Austin TX

International Classification:

H04N009/47

US Classification:

348 95

Abstract:

A system and method are described for an image registration system and method including a registration engine that receives complex image data for corresponding images. The registration engine generates a correlation map between the complex image pair for relative translation by calculating an inverse of the complex conjugate product of the frequency data of the first image and the frequency domain data of the second, corresponding, image. The frequency domain data may be obtained using Fast Fourier transform-based techniques.

Abstract:

In digital holographic imaging systems, streamed holograms are compared on a pixel-by-pixel basis for defect detection after hologram generation. An automated image matching, registration and comparison method with feedback confidence allows for runtime wafer inspection, scene matching refinement, rotational wafer alignment and the registration and comparison of difference images.

US Classification:

345419, 359 9

Abstract:

System and method for video holographic display. Information is received regarding a 2D hogel array with multiple hogel apertures, specifying number, size, and/or spacing of the hogel apertures. Information regarding a 3D scene is received, including a scaling factor mapping the 3D scene to a 3D display volume. Due to gradual variation of radiation patterns from hogel to hogel, a full set of color radiation intensity patterns for the entire hogel array may be generated by interpolating the color radiation intensity patterns from a sparse subset of the hogels without having to compute all of the patterns. The full set of color radiation intensity patterns may then be used to holographically display the 3D scene.

Abstract:

Methods and devices for a parallel multi-processor encoder system for encoding video data. The video data comprises a sequence of frames, wherein each frame comprises a plurality of blocks of pixels in sequential rows. For each frame, the system divides the plurality of blocks into a plurality of subsets of blocks, wherein each subset of blocks is allocated to a respective processor of the parallel multi-processor system. Each respective processor of the parallel multi-processor system may sequentially encode rows of the subset of blocks allocated to the respective processor and sequentially transmit each encoded row of blocks as a bit stream to a decoder on a channel. For each row, the respective encoded row of blocks is transmitted to the decoder for each processor prior to transmission of the next sequential respective encoded row of blocks for any processor. Additionally, a similar parallel multi-processor decoder system is described.

Abstract:

A birdwatching system for identifying, locating, and tracking birds of interest while birdwatching. The birdwatching system may comprise an apparatus, such as shaft, which includes a plurality of microphones located on a distal end of the shaft for capturing audio signals of a bird, and possibly video cameras for producing video of the birds. The birdwatching system may further comprise a device, such as the user's tablet device, which receives audio data from the plurality of microphones and processes the audio data (locally of via a remote server) to determine a bird species and location of the bird. The device may then display an icon in a map of the surrounding area representing the location of the bird. The display may further selectively display information regarding the identified bird species. The birdwatching system may detect, locate, display and track information on a plurality of birds simultaneously.

Abstract:

Methods and systems for rendering an output image from a plurality of input images. The plurality of input images is received, and each input image is taken from a different first location. A view specification for rendering the output image is received, and the view specification includes at least a second location. The second location is different from each of the first locations. An output image is rendered based at least in part on the plurality of input images and the view specification, and the output image includes an image of a region as seen from the second location. The output image is displayed on a display.
