摘要： Various embodiments of the present invention are directed to systems and methods for multimodal object localization using one or more depth sensors and two or more microphones. In one aspect, a method comprises capturing three-dimensional images of a region of space wherein the object is located. The images comprise three-dimensional depth sensor observations. The method collects ambient audio generated by the object, providing acoustic observation regarding the ambient audio time difference of arrival at the audio sensors. The method determines a coordinate location of the object corresponding to the maximum of a joint probability distribution characterizing the probability of the acoustic observations emanating from each coordinate location in the region of space and the probability of each coordinate location in the region of space given depth sensor observations.

摘要： Methods and systems are disclosed for processing image frames to reduce the bandwidth requirements. Embodiment of the present invention may include mode-specific image frame rendering in photorealistic and non-photorealistic modes, such as outline and cartoon modes. In embodiments, update regions may be identified and reduced by an edge position mask. In embodiments, update regions may be bounded by rectangles and such regions may be reduced in number by merging regions together using various no-cost or cost approaches. To improve compressibility, regions to be transmitted that do not require updating at the receiver may be encoded as transparent.

摘要： A first derived matrix of transport coefficients and a second derived matrix of transport coefficients are derived from a primary matrix of transport coefficients. Each of the transport coefficients describes transport of a respective image forming element from a first position onto one or more image forming elements at a second position. An approximate inverse of the first derived matrix is ascertained. A modified version of a projection image is determined from the projection image, the approximated inverse of the first derived matrix, and the second derived matrix. The modified version of the projection image is rendered from the first position onto a physical medium at the second position.

摘要： Embodiments of the present invention enable fault detection in a printed dot-pattern image. Certain applications of the present invention are its use in various embodiments of a system for inspection of a printed circuit board (“PCB”) substrate. In embodiments, a generated distortion map is based on a comparison of a reconstructed dot-pattern image, a simulated reference bitmap, and an error map representing differences between the reconstructed dot-pattern image and the reference bitmap. In embodiments, the pixels of the distortion map are color coded to identify the locations and types of aberrations that were discovered as a result of the comparison.

摘要： A projection system uses a transformation matrix to transform a projection image p in such a manner so as to compensate for surface irregularities on a projection surface. The transformation matrix makes use of properties of light transport relating a projector to a camera. If the resolution a camera is lower than that of a projector within said projection system, then the transformation matrix will have holes where image data corresponding to a projector pixel will have been lost. In this, case, new image are generated to fill-in the holes.

摘要： For each of multiple image pixels, input color component values of the pixel in an input device-dependent color space are transformed to output color component values in an output device-dependent color space characterized by an output color gamut defined by a respective gamut range for each of the output color components. In this process, the input color component values of the pixel are multiplied with corresponding elements of a device-dependent characterization matrix to produce a set of product values. The output color component values are derived from the product values. The values of a particular one of the output color components are ascertained based on a continuous nonlinear companding function that maps a function input value derived from one or more of the product values to a function output value that increases monotonically with increasing function input values over the respective gamut range of the particular output color component.
