Methods and systems for detecting expiration time of an article include receiving the article for a pre-planned event. The article is analyzed to identify one or more attributes. The article is matched to an event identifier using the article attributes. The event identifier is pre-defined and stored in an event database. The event identifier acts as an index to the event database for obtaining event characteristics of the pre-planned event. The article attributes are examined to identify event phase indicators that correlate to a specific event phase of the pre-planned event. The expiration time of the article is computed based on the specific event phase identified for the pre-planned event. The expiration time is used to rank the article and for considering assigning the article to a content pool of articles that is selected for publishing for the specific event phase of the pre-planned event.

A processor-implemented method and system for detecting objects in a media file using a block based histogram of oriented gradients methodology is described. At least one image representing at least one frame of a video sequence comprising one or more objects of at least one desired object type is received. A region of interest contained in a block of frame is considered. An array containing magnitude and angle values is calculated, normalized for each pixel in the block in the internal memory. The normalized array is aggregated, ported and stored in an external memory. A value or block of values of the aggregated array in the external memory along with the specific feature vector is transferred to the internal memory. Based on a comparison of each value in the aggregated array and the specific feature vector, a desired object type is detected.
