Abstract: The present teaching relates to impression count determination. A forecasting time series (TS) model is established based on measured impression counts (MI-counts). Metrics are calculated from MI-counts from a sub-range of a profile. Different types of data characteristics are detected based on the metrics. Hybrid correction applied to the profile is determined based on the detected data characteristics. Corrected impression counts (I-counts) for the profile are generated via the hybrid correction operation based on the MI-counts and I-counts estimated from the forecasting TS models and provided for determining a level of viewership of the content at the site.

Abstract: A neural network is used to model to model the joint distribution of attributes across multiple health surveys. These multiple health surveys include large scale survey datasets and small scale survey datasets. The neural network model is trained using a combined dataset of the large scale survey datasets and the small scale survey datasets. The large scale survey datasets and the small scale survey datasets may include missing value indicators. The joint distribution of attributes modeled by the neural network model are the used to impute substitute values for the missing values to thereby create an output large scale dataset that does not include missing values.

Abstract: A method, non-transitory computer readable medium and apparatus for calculating a by spot occupancy of a parking lot are disclosed. For example, the method includes receiving an indication of a triggering event, sending a query to receive a first image and a second image in response to the triggering event, receiving the first image and the second image, analyzing the first image and the second image to determine a change in an occupancy status of a parking spot within the parking lot and calculating the by spot occupancy of the parking lot based on the change in the occupancy status of the parking spot.

Abstract: A three-dimensional object printer is configured to generate a printed predetermined test pattern on a substrate in the printer with a plurality of ejectors in a printhead. An image sensor generates image data of the printed test pattern and a controller identifies a z-axis distance between the printhead and the substrate using a dispersion identified between cross-process direction distances separating printed marks in the test pattern.

An image sensor generates image data of the printed test pattern and a controller identifies a z-axis distance between the printhead and the substrate that receives the test pattern with reference to an identified dispersion between cross-process direction distances separating printed marks in the test pattern.

Abstract: A method, non-transitory computer readable medium, and apparatus for calculating a transaction quality score of a merchant are disclosed. For example, the method analyzes fraudulent transaction data in a fraudulent transaction data table for each one of a plurality of merchants, calculates a transaction quality score for the each one of the plurality of merchants based on the fraudulent transaction data, filters the plurality of merchants having a respective transaction quality score above a threshold and transmits the plurality of merchants having the respective transaction quality score above the threshold for display.

Abstract: A device management application (DMA) contacts printing devices connected to a computer network to obtain the device type, configuration parameters, and configuration settings from the printing devices. The device type, the configuration parameters, and the configuration settings are stored for each of the printing devices in a nested hash table. The configuration settings are grouped for each of the printing devices by device type in a working file, such as an XML tree that has leaf nodes for each configuration parameter of each different device type group. These methods identify the most common configuration settings for each of the configuration parameters in the leaf nodes, and map the most common configuration settings for the configuration parameters to configuration setup files for each the device type group. The configuration setup files are then deployed to the printing devices.

Abstract: A three-dimensional object printer ejects drops of a build material from a plurality of ejectors in a first printhead to form an object on a first region of a member and ejects drops of a support material from a plurality of ejectors in a second printhead to support the object on the first region of the member. The second printhead ejects drops of the support material onto a second region of the member that is separate from the first region to form a substrate layer. The first printhead ejects drops of the build material onto the substrate layer to form a printed test pattern. An image sensor generates image data of the printed test pattern to identify an inoperable ejector in the first printhead.

Abstract: A method, system, and apparatus for license plate relighting comprises collecting an image of a license plate, performing license plate recognition on the image of the license plate; calculating a confidence metric for the license plate recognition; and performing a shadow detection and relighting method if the confidence metric is below a predetermined threshold, comprising identifying a shaded region of said license plate, determining if the shaded region is actually shaded, and relighting the actually shaded region.

Abstract: Methods and systems for localizing numbers and characters in captured images. A side image of a vehicle captured by one or more cameras can be preprocessed to determine a region of interest. A confidence value of series of windows within regions of interest of different sizes and aspect ratios containing a structure of interest can be calculated. Highest confidence candidate regions can then be identified with respect to the regions of interest and at least one region adjacent to the highest confidence candidate regions. An OCR operation can then be performed in the adjacent region. An identifier can then be returned from the adjacent region in order to localize numbers and characters in the side image of the vehicle.
