Title: Two dimensional MSMS acquisition modes
Inventor: JASON LEE WILDGOOSE
IPC: H01J49/00
Filed: 2015-06-11
Abstract: Fragment ions derived from reacting precursor ions are mass analysed in a number of consecutive time intervals wherein the intensities of spectral data obtained in a first interval between T0 and T1 are summed to determine a first summed intensity for each fragment ion associated with the first time T1, further summed intensities are then obtained for the following time intervals T1 to T2 and T2 to T3. A peak intensity centroid is determined for each time interval and their values are then used to identify a precursor ion. The mass spectroscopy method is useful for systems where the rise/fall time of the spectral features is less than a time bin duration such as low resolution scanning quadrupoles.

Title: Method and apparatus for encoding image, and method and apparatus for decoding image
Inventor: BAE KEUN LEE
IPC: H04N19/80
Filed: 2012-11-02
Abstract: Reference samples (e.g. a(0,0), to r(0,0)) are generated for a 4x4 current block by deriving a first sub-sample (e.g. a(0,0), b(0,0), c(0,0)) based on a horizontal interpolation filter and then deriving a second sub-sample (e.g. e(0,0) to r(0,0)) based on a vertical interpolation filter, where the vertical filter uses values calculated from the first sub-sample. The first sub-sample is derived using a first shifting value and an 8-tap horizontal interpolation filter. The second sub-sample is one of two quarter position samples (e.g. e(0,0), p(0,0)) and a half position sample (e.g. i(0,0)), and is vertically aligned below the first sub-sample (e.g. a(0,0)). The second sub-sample is derived based on a second shifting value and an 8-tap vertical interpolation filter. The first and second shifting values are based on a bit-depth of a luma component and a constant value respectively. Prediction samples of a current block are obtained using the reference samples. Residual samples of a current block are derived by inverse-quantizing residual coefficients obtained from a video signal and performing an inverse transform on the inverse-quantized residual coefficients. The current block is reconstructed using the residual samples and the prediction samples.

IPC: G06T7/223
Filed: 2019-01-17
Abstract: A method of processing a video is provided. The method includes detecting a region of interest (ROI) 105 in a detection frame of the video and estimating a motion of the region of interest between the detection frame and an estimation frame of the video subsequent to the detection frame 110.

Based on the projected motion, a position of the region of interest in the estimation frame is evaluated. Multiple estimation frames may be used. The frame sequence may be determined on the basis of thresholding confidence levels. The ROI may be identified via a convolutional neural network (CNN). The frames may be subdivided into a grid of portions (310, Fig. 3). The tracking may comprise block matching. The estimated position of the region of interest may be stored as metadata associated with the estimation frame. An apparatus for processing a video and a related non-transitory computer-readable storage medium comprising a set of computer-readable instructions are also provided.

Title: Method and system for locating an acoustic source
Inventor: MAHMOUD FARHADIROUSHAN
IPC: G01V8/24
Filed: 2012-06-06
Abstract: A method of determining the location of an acoustic source 200 comprises providing a distributed optical sensor deployed in an area to be monitored and receiving one or more acoustic signals from the source at a plurality of sensing points spatially distributed along the length of the sensor. Each acoustic signal is received at two or more respective sensing points at different respective times to obtain a two-dimensional spatiotemporal data set. The signals are processed by separating a received acoustic signal into its component frequencies and phase shifting the data set in dependence on the component frequencies, a known speed of sound through the surrounding medium and an estimate value for the shortest distance between the source and the sensor. A plurality of cost functions are calculated based upon the phase shifted data and a shortest distance 203 between source and sensor is determined using the shortest distance estimate used to calculate the maximum cost function, thereby allowing determination of the location of the source relative to at least one sensing points.
