Nonlinear Error Correction for Color Phase-Shifting Profilometry with Histogram Equalization [PDF]
Photonics, 2022 Because color patterns with multiple channels can carry more information than gray patterns with only one channel, color phase-shifting profilometry (CPSP) has been widely used for high-speed, three-dimensional (3D) shape measurement.

An Efficient Prediction-and-Shifting Embedding Technique for High Quality Reversible Data Hiding
EURASIP Journal on Advances in Signal Processing, 2010 The embedding capacity of a histogram-based reversible data hiding technique is primarily determined by the peak height of the histogram. Recently, some studies have tried to embed data in the histogram of prediction errors by modifying the error values ...
