Implementation of Logarithmic Polar Coordinate Transformation for Images
Implementation of image logarithmic polar coordinate transformation with rotation invariance, applicable for geometric attack resistance in digital watermarking systems
Log-Polar Coordinate Transformation of an Image
Performing log-polar coordinate transformation on an image to prepare for Fourier-Mellin transform, converting rotation parameters into translation parameters with implementation details
Program for Implementing Log-Polar Coordinate Transformation
A program designed to perform log-polar coordinate transformation in image processing. When parameters need to be obtained for rotated or scaled images, log-polar transformation must be applied first, followed by phase correlation method calculations.
