How to get particular or all the points/positions of the object in the image after using TextureLoader.load()

Hi Professionals,

After using Textureloader.load to get a texture (image), how to get the points of that image with callback function or any other ways? Please kindly advise. Thanks.

What do you mean by points?

Thanks for your reply.

If I use Textureloader to load the images as attached, how can I get the object positions/points in the image with color or black/white, like the bottle or the person?
