Abstract: A system for identifying an Object Impression (OI), indicative of the viewability of an object over a time period during which a plurality of frames are displayed to a user, exceeding a threshold, the system comprising a processing resource configured to perform the following: for each frame of the plurality of frames, calculate a Frame OI Value (FOIV), based on an object's viewability score calculated for the corresponding frame, wherein the object's viewability score is calculated based on a first value indicative of a relative portion of the object from the viewport and a second value indicative of a relative portion of the object visible in the viewport, and a time duration during which the corresponding frame is displayed; and, aggregate the FOIVs calculated for the plurality of frames, giving rise to an Aggregated OI Value (AOIV), such that upon the AOIV exceeding a second threshold, the OI is identified.

Abstract: A system for calculating viewability scores of objects displayed within a viewport, the system comprising a processing resource configured to perform the following for at least one object of the objects: determine a first value indicative of a relative portion of the object from the viewport; and calculate a viewability score of the object, wherein the viewability score is calculated based on the first value.
