  • Technology for capturing, transmitting, and analyzing images of objects
    Patent number: 10319094
    Abstract: A system for analyzing images of objects such as vehicles. According to certain aspects, the system includes a user interface device configured to capture a set of images depicting a target vehicle, and transfer the set of images to a server that stores a set of base image models. The server analyzes the set of images using a base image model corresponding to the target vehicle, a set of correlational filters, and a set of convolutional neural networks (CNNs) to determine a set of changes to the target vehicle as depicted in the set of images. The server further transmits, to the user interface device, information indicative of the set of changes for a user to view or otherwise access.

    Abstract: Seismic survey data is received, indexed into index sets, and each index set partitioned into data blocks. For each particular data block of a particular index set, the particular data block is sliced into frequency slices. For each particular frequency slice of the particular data block, the particular frequency slice is processed to remove random and erratic noise by: forming a Hankel matrix from the particular frequency slice: determining an optimal rank for the Hankel matrix, determining a clean signal and erratic noise from the ranked Hankel matrix, and returning the clean signal and erratic noise for the particular frequency slice. A clean signal is assembled from the index sets.
