A perimeter (105) around a detected object, such as face (103), in a video frame 1309 is generated in a first coordinate system. The perimeter is converted from the first coordinate system into a second coordinate system having the same aspect ratio as the first coordinate system. A first metadata entry includes dimensions of the image data in the second coordinate system. A second metadata entry provides a location and dimensions of the converted perimeter in the second coordinate system. Additional metadata can indicate matching objects between frames, position of an object relative to other objects in a frame, a probability that an object is correctly detected, and a total number of objects detected across multiple frames of image data. Claims are also included for the transmitting and receiving of the generated metadata. |
