the problem of image registration, that Liu shows image
registration processes in Figures 1 and 2 and that Miller teaches
the need for mapping, i.e. registering onto a 3-D model. The
position is taken that one of ordinary skill in the art would have
combined Liu and Margalit to improve Liu’s registration and
combined those teachings with Miller to apply texture to the model
created by Liu.
We will not sustain the rejection of claims 21-39. It is
considered that the examiner has not established the requisite
motivation for combining the references. There is no evidence or
rational provided by the examiner establishing that combining
Margalit with Liu would have improved Liu’s registration as
asserted. Furthermore, Liu is concerned with object recognition
using multiple 2-D camera views. 3-D object recognition is
accomplished by matching
sequentially input 2-D silhouette shape features against those of
model shapes taken from a set of fixed camera views. The
examiner’s answer does not draw attention to any specific
disclosure in Liu in support of the conclusion that Liu is
concerned with building a model of a 3-D region for viewing images
of the region from multiple positions and no such disclosure is
