Systems and methods for detecting and tracking humans in captured images

A method for detecting and tracking humans from one image to another image captured by a camera at a retail store, the method comprising:

• capturing, at a first time by a camera, a first image of an area at a retail store;
• receiving, by a control circuit coupled to the camera, the first image;
• detecting, by the control circuit, a plurality of key body joints of a first human captured on the first image, wherein each of the plurality of key body joints is a point of interest along a skeletal anatomy of the first human;
• in response to the detection of the plurality of key body joints, determining segmentations of the plurality of key body joints of the first human to determine one or more body parts of the first human;
• determining, by the control circuit, a color distribution map of aggregate pixels associated with each body part of the one or more body parts of the first human on the first image, wherein each color distribution map is used by the control circuit to differentiate between the first human and another human in the first image;
• and
• causing, by the control circuit, a database to store the color distribution map for each body part of the first human on the first image, wherein the database comprises one or more color distribution map sets each associated with a detected human in a captured image of the camera.
