PHASE ERROR ANALYSIS AND CORRECTION FOR CROSSED-GRATING PHASE-SHIFTING PROFILOMETRY

Crossed-grating phase-shifting profilometry (CGPSP) has great utility in three-dimensional shape measurement due to its ability to acquire horizontal and vertical phase maps in a single measurement.However, CGPSP is extremely sensitive to the non-linearity effect of a digital fringe projection system, which is not studied in depth yet.In this paper

Fabric image retrieval, a form of content based image retrieval, is a high value research with the potential to be applied in many fields, such as e-commerce and inventory management.However, this research hotspot is plagued by two read more major challenges, namely the high requirements for retrieval results and the peculiarities of fabric images.
