Abstract: Systems and techniques of the present disclosure may correct sensed data to account for an offset position of an imaging tool that is deployed in a wellbore. When an imaging tool is deployed at a location that does not coincide with a center point of the wellbore, images generated from acquired data may be distorted as some of image data will be collected at locations closer to a wellbore wall than other image data. Since the resolution of a sensing device varies with distance, the resolution of data collected by a sensing device will vary with distance that separates the sensing device from the wellbore wall. Furthermore, judgments of distance to features of the wellbore wall may also be distorted because of this offset. As such, systems and techniques of the present disclosure are directed to adjust collected image data to correct for both distance and resolution related effects.

Abstract: At least one aspect is directed to determining an estimate of an intersection of user identifiers in a first set of user identifiers and a second set of user identifiers. The first and second sets of user identifiers can be populated with user identifiers that have interacted with the same content item or content item campaign. Estimates of intersections of the first and the second sets can be determined based on a binomial vector approach, a vector of counts approach, or a hybrid approach. The binomial vector approach generates vectors based on k hashes of each user identifier in the first set and summing the vectors to generate a first vector. The intersection can be determined based on a dot product of the first vector and a second vector similarly generated from the second set of user identifiers.
