Abstract: A method and system for determining a position of an object with respect to a semi-transparent container, by: receiving, from a camera attached to a semi-transparent container, an image of a scene in proximity to the semi-transparent container; detecting, by an object detector, a new object present in the image, else marking the image as being an image indicative of a current state of the semi-transparent container; cropping, by a computer processor, the image to produce a cropped object image; analyzing, by the computer processor, the cropped object image; and assigning, by the computer processor, a confidence score in a numeric range to the cropped object image, wherein a score at one end of the range indicates the new object corresponding to the cropped object image is inside the semi-transparent container, and wherein a score at the other end of the range indicates the new object is outside.
