  • Patent number: 10686968
    Abstract: A motion detection method includes an extracting circuit generating a first representative data according to a first image in an image signal outputted by an image sensor, a buffering circuit storing the first representative data, the extracting circuit generating a second representative data according to a second image in the image signal, the buffering circuit storing the second representative data and outputting the first representative data to a comparing circuit, and the comparing circuit comparing the first representative data and the second representative data, to generate a motion detection result. When the motion detection result represents “motion”, an image-signal-processing circuit of an image signal processor enters active state to generate output signal. By means of the motion detection method, in an imaging device, the image-signal-processing circuit of the image signal processor can switch between active state and power-off/power-saving state even when there is no additional infrared sensor.

    Abstract: A motion correction method includes two steps. The first step includes a global motion correction using the bilinear warping technique and a rough delineation of the lung fields. One of the native images (low energy image, high energy image) is deformed to match the other image.

Only tiles with a sufficient high proximity value are taken into account. The maximum shift applied in this second step is limited to a few pixels to avoid strong deformations of the native images.

The method may include operating the computing device in a reduced power state and collecting a first set of data from a first sensor. Based on the first set of data, the computing device determines if an object is within a threshold distance of the computing device and, if the object is within the threshold distance, the device activates a secondary sensor to collect a second set of data. Based on the second set of data, the device determines if the object is a person. If the object is a person, the device determines a position of the person relative to the computing device and executes a change of state in the computing device based on the position of the person relative to the computing device. If the object is not a person, the computing device remains in a reduced power state.

  • Patent number: 10390037
    Abstract: Techniques and tools for video coding/decoding with motion resolution switching and sub-block transform coding/decoding are described. For example, a video encoder adaptively switches the resolution of motion estimation and compensation between quarter-pixel and half-pixel resolutions; a corresponding video decoder adaptively switches the resolution of motion compensation between quarter-pixel and half-pixel resolutions. For sub-block transform sizes, for example, a video encoder adaptively switches between 8×8, 8×4, and 4×8 DCTs when encoding 8×8 prediction residual blocks; a corresponding video decoder switches between 8×8, 8×4, and 4×8 inverse DCTs during decoding.

  • Patent number: 10390039
    Abstract: Innovations in motion estimation adapted for screen remoting scenarios are described herein. For example, as part of motion estimation for a current picture, a video encoder finds a pivot point in the current picture, calculates a hash value for the pivot point, and searches for a matching area in a previous picture. In doing so, the video encoder can calculate a hash index from the hash value and look up the hash index in a data structure to find candidate pivot points in the previous picture. The video encoder can compare the hash value for the pivot point in the current picture to a hash value for a candidate pivot point in the previous picture and, when the hash values match, compare sample values around the respective pivot points. In this way, the video encoder can quickly detect large areas of exact-match blocks having uniform motion.

    Abstract: A video encoding device (2) includes a side information determination section (21) and a side information encoding section (22). The side information determination section (21) sets a quantization parameter for each macroblock in such a manner that a difference between quantization parameters for each pair of macroblocks with successive encoding orders is equal to one of n difference values, and transforms the difference into one of n indices with respect to each pair. The side information encoding section (22) generates a binary sequence having a length corresponding to the size of the absolute value of the index.
