  • Publication number: 20200003693
    Abstract: An imaging apparatus (20) includes an interface (50) and a processor (30). The interface is configured to receive a sequence of images of an object (38) acquired at respective acquisition times, the object is labeled with fluorescent emitters. The images depict intensity fluctuations of emitters on an acquisition grid, and the intensity fluctuations being uncorrelated among the emitters and during an overall time over which the images in the sequence are acquired. The a processor is configured to calculate a temporal correlation function of the intensity fluctuations over the sequence of images, and to estimate locations of the emitters on a super-resolution grid having a higher resolution than the acquisition grid, by applying to the temporal correlation function a recovery process in which the locations on the super-resolution grid are assumed to be sparse or compressible in a predefined domain. The recovery process includes a sparse-recovery process or a regularized process.

  • Publication number: 20190365355
    Abstract: An apparatus (20) for imaging includes an input interface (54) and a processor (50). The input interface receives a sequence of input images of a target. Each input image includes a grid of pixels representing reflections of a transmitted signal from reflectors or scatterers in the target. A resolution of the input images is degraded by a measurement process of capturing the input images in the sequence. The processor derives, from the sequence of input images, an aggregated image in which each pixel comprises a statistical moment calculated over corresponding pixels of the input images, and converts the aggregated image into a super-resolution image of the target, having a higher resolution than the input images, by applying to the aggregated image a recovery function, which outputs the super-resolution image as a solution to the recovery function, provided that the reflectors or scatterers are sparse or compressible in a predefined transform domain.

  • Patent number: 10393869
    Abstract: A method includes receiving a signal, which includes reflections of multiple pulses from one or more targets (24). A Doppler focusing function, in which the reflections of the multiple pulses from each target accumulate in-phase to produce a respective peak associated with a respective delay and a respective Doppler frequency of the target, is evaluated based on the received signal. Respective delays and Doppler frequencies of the targets are estimated based on the Doppler focusing function.

  • Patent number: 9778557
    Abstract: A method includes receiving from multiple transducers respective signals including reflections of a transmitted signal from a target. An image of the target is produced irrespective of sparsity of the received signals, by computing transducer-specific frequency-domain coefficients for each of the received signals, deriving, from the transducer-specific frequency-domain coefficients, beamforming frequency-domain coefficients of a beamformed signal in which the reflections received from a selected direction relative to the transducers are emphasized, and reconstructing the image of the target at the selected direction based on the beamforming frequency-domain coefficients.

  • Patent number: 9143194
    Abstract: A method includes accepting an analog input signal that includes a sequence of pulses. The analog input signal is filtered so as to produce a filter output, using a filter whose time-domain response is confined to a finite time period and whose frequency-domain response is non-zero at a finite set of integer multiples of a frequency shift ??, and is zero at all other integer multiples of ??. The filter output is sampled so as to produce digital samples. Respective amplitudes and time positions of the pulses in the sequence are calculated based on the digital samples.

  • Patent number: 8228218
    Abstract: A method of reproducing an original analog signal modified by a distortion and sampled. The distortion may be linear or nonlinear, and the samples may be either ideal or non-ideal. The method determines a stationary point of a cost function based on an error vector. The method iteratively computes approximated analog signals until the approximated analog signals converge to the original analog signal. The method may utilize Fr?chet derivatives and Moore-Penrose pseudo inverse transformations in order to iteratively compute the original analog signal. An apparatus performing said method is also disclosed.
