Electronic device and method for controlling the electronic device thereof

An electronic device comprising:

• at least one memory storing at least one instruction;
• and
• at least one processor connected to the at least one memory and configured to execute the at least one instruction to:
• input information about a first frame among a plurality of frames to a first object detection network and obtain first information about an object included in the first frame,
• store the first information in the at least one memory, and
• input the first information and information about a second frame among the plurality of frames to a second object detection network and obtain second information about an object included in the second frame,
• wherein the second frame is a next frame following the first frame,
• wherein the first object detection network and the second object detection network are separate object detection networks,
• wherein the first object detection network is trained to obtain information about an object by using a plurality of anchor boxes, and
• wherein the at least one processor is further configured to execute the at least one instruction to:
• obtain the first information using an anchor box located in a first grid among a plurality of grids, and
• obtain the second information by:
• using a bounding box, as an anchor box, of the object included in the first frame located in the first grid,
• using a bounding box, as an anchor box, located in a second grid among the plurality of grids around the first grid based on information about a motion of the object included in the second frame, or
• using a bounding box, as an anchor box, located in the first grid and a plurality of third grids from among the plurality of grids located at an upper, lower, left, or right portions of the first grid.
