Method and apparatus for determining displacement information of target area and method and apparatus for determining atmosphere information using the same

An apparatus for determining displacement information, the apparatus including:

• one or more hardware processors configured to:
• set a target area within a target frame in which an object is positioned to determine displacement information of the target area, and
• determine a tracking area in a tracking frame based on displacement information of at least one neighboring target area of the target area, the at least one neighboring target area being assigned a value based on a respective distance to the target area, and
• determine the displacement information associated with the target area in the tracking area.

A method of determining atmosphere motion information, the method comprising:

• setting a target area used, in a target frame, to determine atmosphere motion information;
• determining a tracking area in a tracking frame based on displacement information of a neighboring target area of the target area;
• tracking a matching area in the tracking area that matches with the target area and determining displacement information of the target area according to the matching area being tracked;
• determining altitude information of the target area;
• and
• determining the atmosphere motion information by reflecting the displacement information and the altitude information of the target area.
