摘要： Example implementations include a method, apparatus and computer-readable medium for generating a visual model of a uniform, comprising detecting a plurality of persons in one or more images. The implementations further include generating a sub-image depicting the respective person from the one or more images for each respective person of the plurality of persons. Additionally, the implementations further include identifying one or more articles of clothing worn by the respective person, executing at least one transformation that adjusts pixels of the sub-image such that the one or more articles of clothing depicted in the sub-image fit in a common template, calculating variance values between a plurality of transformed sub-images comprising the sub-image transformed by the at least one transformation and other sub-images generated for other persons in the plurality of persons and transformed by the at least one transformation, and generating a virtual model based on the variance values.

摘要： Example implementations include a method, apparatus and computer-readable medium for computer vision detection of dwell time, comprising receiving a plurality of indications of persons entering an environment over a period of time. The implementations further include adding, into a first-in-first-out (FIFO) queue, a respective identifier of a respective person entering the environment and an entry time for each of the plurality of indications, removing, from the FIFO queue, the respective identifier and the entry time of the respective person in response to an indication of an exit of the respective person from the environment at an exit time, calculating an estimated dwell time of the respective person based on a difference in the entry time and the exit time, and generating an alert based on calculating an average dwell time of the persons entering the environment over the period of time based on each estimated dwell time.
