Method and apparatus for creating a media sequence with automatic selection of an optimal sequence preset

摘要

A method and apparatus for creating a media sequence with an optimal sequence preset comprising accessing a plurality of media, wherein each media file in the plurality of media files comprises at least one frame comprising at least one object; calculating a sequence perimeter based on a union of a plurality of calculated frame perimeters for the plurality of media files, wherein the frame perimeter comprises each of the at least one objects in the at least one frame of the plurality of files; determining a sequence preset within a threshold of the calculated sequence perimeter; creating a sequence using the determined sequence preset; importing into the sequence that portion of the at least one frame of each media file in the plurality of media files that is within the calculated frame perimeter; and aligning each calculated frame perimeter of each file imported into the sequence with the sequence preset.

1. A computer-implemented method for creating a sequence from a plurality of media files, the method comprising:
accessing the plurality of media files, wherein each media file of the plurality of media files comprises at least one frame comprising at least one object; for the at least one frame of each of the plurality of media files, determining, by at least one processor, a frame perimeter with a smallest size that encompasses the at least one object in the at least one frame of each of the plurality of media files by:
accessing the at least one frame;determining whether at least one face exists in the at least one frame;calculating a body perimeter that encompasses a body associated with the at least one face when the at least one face is detected;determining the frame perimeter such that the frame perimeter has a smallest size that encompasses the calculated body perimeter;calculating, by the at least one processor, a sequence perimeter with a smallest size that encompasses all of the frame perimeters determined for the plurality of media files; determining, by the at least one processor, a sequence preset frame perimeter based on the calculated sequence perimeter; and creating the sequence using the determined sequence preset frame perimeter by:
importing into the sequence that portion of the at least one frame of each media file in the plurality of media files that is within the calculated frame perimeter; andaligning each calculated frame perimeter of each file imported into the sequence with the determined sequence preset frame perimeter.
