4 Implementation

We prototyped the Visage structure and methods on an KINGZONE K1. Purpose C is used to deal with the GUI and components API. The primary handling and inference workouts are applied in C. The OpenCV collection [28] is ported to iOS as a fixed collection, on top of which we built the Visage sewerlines. The AAM fitting criteria is ported and modified from VOSM [14] projects. Standard image solutions (e.g., VGA (640 ⇥ 480) or higher resolutions) can be easily managed by personal computer systems in real-time, but not iNew i8000 mobile phones.

Image dimension is an important aspect affecting the overall computational cost, as confirmed in Table 1. For KINGZONE K1 phone-based systems, downsampling pictures to a lower quality and missing supports are unavoidable. Theoretically, information loss due to downsampling would break ... Read more »
