Abstract: A method for decoding a predetermined block of a picture using intra-prediction by reading, for each of predetermined intra-prediction blocks, from a data stream, a mode index identifying a matrix-based intra-prediction mode is disclosed. Samples of each predetermined intra-prediction block are predicted by computing a matrix-vector product between an input vector derived from reference samples and a prediction matrix associated with the identified matrix-based intra-prediction mode (k)—and associating components of an output vector obtained by the matrix-vector product onto sample positions of the predetermined block. Further predetermined intra-predicted blocks of the picture are predicted to obtain a prediction signal. A transformation flag is decoded from the data stream using context adaptive binary arithmetic coding, and a prediction residual is decoded and re-transformed using a reverse transformation based on the transformation flag to obtain a prediction residual signal.

Abstract: An apparatus for block-wise decoding a picture from a data stream and/or encoding a picture into a data stream, the apparatus supporting at least one intra-prediction mode according to which the intra-prediction signal for a block of a predetermined size of the picture is determined by applying a first template of samples which neighbours the current block onto a neural network. The apparatus may be configured, for a current block differing from the predetermined size, to: resample a second template of samples neighboring the current block, so as to conform with the first template so as to obtain a resampled template; apply the resampled template of samples onto the neural network so as to obtain a preliminary intra-prediction signal; and resample the preliminary intra-prediction signal so as to conform with the current block so as to obtain the intra-prediction signal for the current block.

Abstract: Techniques for block wise encoding and decoding may be applied to encoders, decoders, and methods for encoding or decoding and include assigning, based on a first signalization in the data stream, the predetermined block to the first set or the second set, sorting the assigned set of intra-prediction modes according to intra-prediction modes used for neighboring blocks, neighboring the predetermined block, to obtain a list of intra prediction modes, deriving, for the predetermined block, from the data stream, an index into the list of intra prediction modes, predicting the predetermined block using an intra prediction mode onto which the index points. The decoder or encoder, if the assigned set is the first set of intra-prediction modes, in sorting the assigned set, uses a second mapping which maps each intra-prediction mode of the second set of prediction modes onto a representative one in the first set of intra-prediction modes.

Abstract: A Ground Penetrating Radar (GPR) system makes use of digital circuitry for synchronizing the sampling of a received radar signal with a transmitted radar signal. The digital synchronization achieves improved waveform reproduction and greater receiver sensitivity. Furthermore, the system employs digital circuitry to control the gain of a receiver amplifier. The digitally controlled gain makes it possible to accurately calibrate the amplitude of received radar signals with great precision while achieving good dynamic range.

Abstract: A method for providing image correlation between the images displayed on a PACS system, the method including the steps of: displaying a first image from a first stack of images and a second image from a second stack of images, each stack of images belonging to a different series of image captures for a subject from a particular orientation; determining a spatial location of each image in the first and second stacks of images; receiving a selection signal for an image in the first stack of images; determining a corresponding image in the second stack of images based on the selection signal and the spatial location of the corresponding image; and, displaying the corresponding image. An apparatus for displaying correlated images based on anatomic triangulation.

Abstract: A method of cladding a reduced diameter portion of a cable wherein the reduced diameter portion is created by grinding the external surfaces of the cable. The cladding is placed around the reduced diameter portion of the cable and is likewise reduced in diameter by rolling, hammering, or other external force. In this manner, a cable cladding can be accomplished without adversely effecting the flexibility of the length of cable.

Abstract: The invention concerns a method for depositing an interlining reducing friction and noise on a pitched cable consisting of a metal wire rope with a threaded helix. The preferred method consists in using a thermoplastic filament and raising the pitched cable to a temperature higher than the melting point of the thermoplastic used, and thereupon, winding the filament between the heated threads of the helix so that the flocks or hairs fuse or sinter to the metal wire and adhere.
