To achieve rotation, scale, and translation invariance in Fourier analysis, one can use a technique called scale-invariant feature transform (SIFT). SIFT is a widely used method in computer vision for detecting and describing local features in images.
Here are the steps to achieve rotation, scale, and translation invariance using SIFT in Fourier analysis:
By using SIFT to detect and describe features in the Fourier transformed image, the resulting descriptors are invariant to changes in scale, rotation, and translation. This allows for the matching of features between images with different orientations and scales, and also enables the estimation of the transformation parameters necessary to achieve invariance.
