Manually Draw Lines Around People in Images + Collect the Images

Hi, It is needed to: 1. Collect from the internet random 10,000 images containing people on different poses (sitting, running, half body [but still recognizable easily to be human], raising hands etc.), mainly pictures of 1-2 people. 2. Draw by hand (using a computer) a contour around the people in the pictures, i.e. a line (borders) that separates each one of them from the background. The color of the line must not appear in the images so it'll be unique in across all images, hence easily recognizable by a computer. 3. Submit pairs of files, before and after. 4. During saving the file after drawing, it must keep the same format and general properties such as resolution.
