Abstract
A marker-less camera pose estimation engine (CPEE) with reconfigurable logarithmic SIMD processor is p roposed for the view angle estimation used in mobile augmented reality (AR) applications. Compared to pre vious marker-based approach, marker-less camera pose e stimation can overlay v irtual images directly on natural world without the help of markers. How- ever, they require 150x larger computing costs and large power consuming floating-point operations wher e such requirement severely restrict
