Hybrid projection-reflection method for phase retrieval.
The phase-retrieval problem, fundamental in applied physics and engineering, addresses the question of how to determine the phase of a complex-valued function from modulus data and additional a priori information. Recently we identified two important methods for phase retrieval, namely, Fienup's basic input-output and hybrid input-output (HIO) algorithms, with classical convex projection method...
متن کاملShadow removal method for phase-shifting profilometry.
In a typical phase-shifting profilometry system for the three-dimensional (3D) shape measurement, shadows often exist in the captured images as the camera and projector probe the object from different directions. The shadow areas do not reflect the fringe patterns which will cause errors in the measurement results. This paper proposed a new method to remove the shadow areas from taking part in ...
متن کاملInter-Professional Education: A Reflection on Education of Health Disciplines
The quality of education and its output in the health care services has been strongly considered by educational policymakers and managers. The development of inter-professional collaboration has been identified as an influential strategy to socialize learners in various health care professionals. Sharing knowledge and experiences in Inter-Professional Education (IPE) provides health care stud...
متن کاملReflection Removal Algorithms
Reflection in images is a big problem in photography. This report presents and evaluates three separate algorithms described in literature that attempt to computationally remove reflections. Multiple images are tested on each algorithm and various test cases are shown. The strengths and weaknesses of each algorithm are outlined and evaluated.
متن کاملFrequency shifting for acoustic feedback reduction
Acoustic feedback is a well-known phenomenon in any electro-acoustical real-time system. Whenever the loop gain of a system exceeds 1 for any frequencies, the system becomes unstable: Feeding the amplified sound signal back into the microphone causes a penetrating whistle. Among others, one concept to reduce acoustic feedback is frequency shifting. The implementation of a frequency shifter is e...
