Phase unwrapping recovers the actual surface topography from a calculated phase map,
which is often degraded by a combination of surface defects and measurement noise …

This paper presents a systematic profile recognition and mensuration approach in machine
vision. It can be utilized to recognize and measure the profiles of industrial parts in an …

Laser interferometry in conjunction with the data dependent systems (DDS) methodology is
first used in this paper to eliminate errors caused by instrumentation and software, and to …

A systematic approach for shape/profile mensuration and recognition is presented in this
paper. Object shape and profile, represented by data sampled from its boundary, are coded …

In the process of surface recovery using interferometric methods, a mixture of artifacts, noise,
and errors affect the phase map stage of the process. Based on a methodology called data …
