The invention discloses a method for predicting visual attention area transfer in gray images, which comprises four steps of: determining leaders, searching followers, calculating significant values and ordering the significant values. The step of determining the leaders is to calculate side potentials of all pixels and determine the leaders in the pixels according to the acquired side potentials and a threshold value. The step of searching the followers is to determine the followers of each leader in all the pixels according to the connectivity and the similarity to form different areas, wherein each area may comprise more than one leader, but in the actual computer implementation process, the leader following other leaders is regarded as a follower. The step of calculating the significant values is to calculate the obtained areas respectively, and one area corresponds to one significant value. The step of ordering the significant values is to order all the areas according to the magnitude of the significant values and take the front three areas. The method successfully introduces the selective attention function of a human vision system into a computer vision system, and can simulate and predict attention transfer of a human eye view point among different areas.

Aspects of the disclosure relate to serving content. In one example, while on a shopping trip at a store, a device may scan for wireless network access point information. The scanned information may be compared to a location model store to determine the device's location in the store and how the device is moving through the store. This information may be compared to behavior models. In one example, identifying a behavior model may include comparing the average speed of the device to a single threshold value (faster or slower than this speed?), by comparing the behaviors of the device to a set of pre-determined behavior models (the browser, the list-follower, the single-item purchaser), or by comparing to the device's shopping habits. The behavior model may then be used to select and serve content.

Described herein is a Leader-Follower Additive Manufacturing (AM) system which controls multiple AM Devices (3D Printers) simultaneously in order to minimize human monitoring and control during the mass manufacture of AM products. This is accomplished by combining individual AM device closed-loop feedback control with the ability for AM devices to communicate feedback loop data to other AM devices. The communication of feedback loop data between AM devices during the mass fabrication of AM components improves AM process reliability and repeatability. Within the system, AM devices are able to assume the roles of Leaders or Followers; Leader AM devices lead the Follower AM devices during the fabrication of multiple AM products. If errors occur during the fabrication of the AM products, individual AM devices are able to create and implement solutions that solve fabrication errors and communicate that data with the other AM devices for present and future AM fabrication efforts.
