Systems and methods allow a data labeler to identify an expression in an image of a labelee's face without being provided with the image. In one aspect, the image of the labelee's face is analyzed to identify facial landmarks. A labeler is selected from a database who has similar facial characteristics to the labelee. A geometric mesh is built of the labeler's face and the geometric mesh is deformed based on the facial landmarks identified from the image of the labelee. The labeler may identify the facial expression or emotion of the geometric mesh.
