In this paper we present a framework for combining all the three i.e. color, texture and shape information, and achieve higher retrieval efficiency. The image and its complement are partitioned into non-overlapping tiles of equal size.

Webb14 maj 1993 · The need for two scale parameters is emphasized: a local scale, for describing the amount of smoothing used for suppressing noise and irrelevant details when computing primitive texture descriptors from image data; and an integration scale, for describing the size of the region in space over which the statistics of the local … WebbAbstract—We present a sufﬁcient condition for recovering unique texture and viewpoints from unknown orthographic projections of a ﬂat texture process. We show that four observations are sufﬁcient in general, and we characterize the ambiguous cases.
