A phase estimation method estimates the phase of signal components using a point spread function. The method obtains a point spread function that expresses complex frequencies at a non integer location in terms of integral frequencies, for a complex frequency of a signal at a non integer location in a complex frequency domain. It obtains complex frequencies of the signal for the integral frequencies, and computes a sum of products of the complex frequencies of the signal at the integral frequencies with the corresponding complex values of the point spread function to provide an estimate of phase of the signal at the non integer location.

A method for detecting a braking situation of a vehicle located on a traffic route, which has a task of ascertaining a red component of at least one image area of an image which depicts at least one section of the traffic route, and includes a task of determining the braking situation based on the red component.

A signal which is to be quality-improved often suffers from the quality degradation in the spatial high frequency region more than compared to the spatial low frequency region. Accordingly a quality improvement is performed efficiently by combining the signal to be quality improved with a high frequency portion extracted from a sparse approximation of the signal to be quality improved.

The mobile barcode scanning device also includes an operating system communicatively coupled to the embedded camera, the barcode scanning application, and the user interface system. The visual display provides a viewfinder for the embedded camera in the barcode scanning application. The user-defined pinch-to-window feature is real-time adjustable in size, orientation, and position by at least a two-point touch gesture.

Techniques related to encoding image content for transmission and display via a remote device with improved latency and efficiency are discussed. Such techniques may include skipping one or more of frame capture, encode, packetization, and transmission for a frame based on a skip indicator. One or more selective updates may be captured for the skipped frame and integrated into an encode of a subsequent non-skipped frame, which may be packetized and transmitted for to the remote device for presentment to a user.

A computer system running image processing software receives identification of a geographical area for which an oblique-mosaic image is desired; assigns surface locations to pixels included in an oblique-mosaic pixel map of the geographical area encompassing multiple source images, the oblique-mosaic pixel map being part of a mathematical model of a virtual camera looking down at an oblique angle onto the geographical area; creates a ground elevation model of the ground and vertical structures within the oblique-mosaic pixel map using overlapping source images of the geographical area, wherein the source images were captured at an oblique angle and compass direction similar to the oblique angle and compass direction of the virtual camera; and reprojects, with the mathematical model, source oblique image pixels of the overlapping source images for pixels included in the oblique-mosaic pixel map using the ground elevation model to thereby create an oblique-mosaic image of the geographical area.

An image processing method includes at least following steps: partitioning a picture into a plurality of picture regions, wherein each picture region comprises at least one pixel group row, each pixel group row comprises at least one pixel group, and the picture regions comprise a first picture region and a second picture region horizontally adjacent to each other; and performing flatness check upon a specific pixel group in a pixel group row of the first picture region through using at least one pixel borrowed from the second picture region.

A device for registration of content in a filled-out application form is disclosed. The device is configured for scanning at least one portion of the filled-out application form. The device is configured for extracting filled-out content from the scanned form. The geometrical features of the master form are retrieved. The master form includes one or more anchor fields. Each anchor field has one or more anchor zones and at least one anchor segment. At least one anchor segment has global adjustment parameters and geometrical features. The extracted filled-out content is related to the retrieved geometrical features of a master form to create a new geometrical representation of the extracted filled-out content of the scanned application form. The new representation of the filled-out content based on the global adjustment parameters for the at least one anchor segment is globally adjusted. The globally adjusted filled-out content is locally adjusted.

A method for compensating pixel luminance of a display panel which includes receiving pixel parameters corresponding to sub-pixels of the display panel, receiving an input image, adjusting the input image according to the pixel parameters, and displaying the adjusted input image at the display panel. The pixel parameters include a first pixel parameter of a base luminance level of a base color channel, a first residual determined from performing inter-channel prediction, a second residual determined from performing inter-level prediction, and parameters used in the performing of the inter-level prediction.

A method of extracting error for peak signal to noise ratio (PSNR) computation in an adaptive scalable texture compression (ASTC) encoder. The method includes identifying a pixel positions of a pixel in a coded block. The pixel position corresponds to an index in a decimated weight block. The method extracts an error value corresponding to the identified pixel position for said PSNR computation in said ASTC encoder.
