Panoramic Image Composition Algorithm through Scaling and Rotation Invariant Features

Automatic Panoramic Image Stitching Using Invariant Features

Survey on Rotation , Scaling , and Translation Invariant Watermarking Algorithm

Watermarking is closely related to steganography but in watermarking the hidden data is usually related to cover image. In this paper discussed about algorithms for rotation, scaling and translation (RST) invariant image watermarking. There are mainly two categories of RST invariant image watermarking algorithms. Then, we discuss about various algorithm used for RST invariant image watermarking.

Polynomial-based rotation invariant features

One of basic difficulties of machine learning is handling unknown rotations of objects, for example in image recognition. A related problem is evaluation of similarity of shapes, for example of two chemical molecules, for which direct approach requires costly pairwise rotation alignment and comparison. Rotation invariants are useful tools for such purposes, allowing to extract features describi...

Rotation Invariant Features for HARDI

Reducing the amount of information stored in diffusion MRI (dMRI) data to a set of meaningful and representative scalar values is a goal of much interest in medical imaging. Such features can have far reaching applications in segmentation, registration, and statistical characterization of regions of interest in the brain, as in comparing features between control and diseased patients. Currently...

Rotation-invariant and scale-invariant Gabor features for texture image retrieval

Conventional Gabor representation and its extracted features often yield a fairly poor performance in retrieving the rotated and scaled versions of the texture image under query. To address this issue, existing methods exploit multiple stages of transformations for making rotation and/or scaling being invariant at the expense of high computational complexity and degraded retrieval performance. ...
