Abstract: An ear saddle point of a subject's ear is determined to produce specifications to fit a wearable apparatus to a subject's head. A boundary of the subject's ear in a profile image is determined using a first model. A map of the subject's ear is generated indicating probable locations of a two-dimensional ear saddle point. A most probable location of the two-dimensional ear saddle point is determined based on the probability map. The two-dimensional ear saddle point is projected onto a three-dimensional mesh surface representing the subject's head. A maximum depth of the three-dimensional mesh surface is determined in a defined region around the projected two-dimensional ear saddle point. The ear saddle point is computed based on the projected two-dimensional ear saddle point and the determined maximum depth. Specifications of a wearable apparatus are generated to fit the apparatus to the subject's head based on the computed ear saddle point.
