A algorithm for rotation-invariant texture image retrieval based on Log Gabor wavelet;

A rotation-invariant and multi-scale generalized roughness feature is presented and itwas combinded with an adaptive weighted distance to apply in texture retrieval.

A rotation-invariant denoising algorithm is proposed for restoring noisy images with cyclicr and dihedral symmetries.

In order to effectively classify and recognize multiple targets with rotation invariance,an artificial neural network named Learning Vector Quantization Network(LVQ network) was proposed to combine with the technology of optical correlated recognition.

A linear discrimination function (d(w, x)=w′x) is presented to classify two aircrafts (the bomber and the fighter) with rotation invariance.

A method of obtaining a binary linear discrimination function ( d m(x)=w x ) with rotation invariance is presented.

In this paper,we incorporate Fourier transform with Log-Polar transform to achieve rotation invariant texture analysis.

A nice matchimg method must possess the advantages of high matching precision, fast matching speed and the property of rotation invariant.

How to extract the Rotation invariant feature is still an unsolved problem of the area of content-based 3D models retrieval.
