Abstract: A method for processing an image includes receiving an input image including a signal and noise, and generating a filtered image based on the input image by removing at least a portion of the noise from the input image. A portion of the signal is also removed from the input image. The method further includes generating a residual image based on the input image. The residual image comprises the at least a portion of the noise and the portion of the signal that are removed from the input image to generate the filtered image. The method also includes identifying at least some of the portion of the signal that is in the residual image, and inserting the at least some of the portion of the signal identified in the residual image into the filtered image.

Abstract: A hydroponic growing apparatus, system, and method is provided. The hydroponic grower includes one or more seed beds each having a length and a width operably supported by a framework. A seed belt is rotatable around each of the one or more seed beds between loading and offloading positions to and from a seed growing position. Seed is discharged onto the seed belt for hydroponically growing a seed atop of the one or more seed beds. Seed growth can be offloaded through the path of a stream of liquid exiting a liquid nozzle for cutting through offloaded seed growth in at least one direction.

Abstract: A method for use in surveying a subsurface region beneath a body of water by detecting compressional, P, waves propagating through the body of water includes locating one or more sensor systems in the water at or close to the subsurface region, using the or each sensor system to detect P waves in the water, and translating all or a portion of the data representing the detected P waves to a higher level above the subsurface region. In the method, the effects of S waves, propagating in the subsurface and converted at the water/subsurface interface into P waves propagating in the water or along the seabed interface, in the translated data is reduced.

Abstract: The present disclosure relates to a method and system for monitoring a wellbore object using a reflected pressure signal. The method discloses providing at least one pump for performing hydraulic fracturing or a source of hydraulic pulse so that pressure signal propagates along the wellbore and reflects from the borehole objects; providing pressure sensor at wellhead; preprocessing of registered reflected pressure signal and pump noise; transforming the registered reflected pressure signal and pump noise from the frequency domain into time-frequency representation with Short Time Fourier Transform (STFT), computing a pump noise mask; applying the pump noise mask to the STFT representation to obtain a filtered reflected pressure signal; processing of the filtered reflected pressure signal for determining the reflection time from the downhole object, calculating the depth of the downhole object from reflected pressure signal by multiplying of the reflection time by the pressure signal propagation velocity. This method allows to perform wellbore monitoring without stop of current operations.
