Speckle displacement images sequence data.zip

Data Usage:This dataset aims to test the displacement measurement performance using the phase-based optical flow method with the complex steerable pyramid.Data Description:This dataset includes 3 simulated speckle displacement image sequences and 1 experimental speckle displacement image sequence.The simulated speckle displacement image sequences include:A translational motion sequence with a displacement range of 0-1 pixels, containing 11 images with a size of 140x140 pixels and a CSV file with ground truth displacement values.A translational motion sequence with a displacement range of 0-9 pixels, containing 91 images with a size of 1600x1200 pixels and a CSV file with ground truth displacement values.A sinusoidal vibration motion sequence with an amplitude of 1 pixel, containing 121 images with a size of 1600x1200 pixels and a CSV file with ground truth displacement values.The experimental speckle displacement image sequence includes:A translational motion sequence with a displacement range of 0-1.1 pixels, containing 45 images with a size of 1600x1200 pixels and a CSV file with ground truth displacement values. These experimental images were generated by decoding the source image files provided by the "Experimental image dataset for validation of the noise-induced bias that affects Digital Image Correlation" using DCRAW software.
