Annotate Human Head Positions in Images - repost

Annotate images in Photoshop by overlaying bounding rectangles on top of the heads of the people in each image. There are 400 images showing at most 5 people at a time. Requirements: - draw tight bounding boxes around each person's head - do this for any situation including frontal, lateral and views from the back - use the same color every time for the same person (even when viewed from the back) - the same 5 individuals are shown in the images; choose a color for each person and consistently use it throughout; for instance you can use pure colors such as: red, green, blue, cyan, magenta - save JPEG at maximum quality settings - save each image with the same name as the original
