Abstract : Content-based image retrieval is the research of images from database, that are
visually similar to given image examples. Gabor functions and Gabor filters are regarded as
excellent methods for feature extraction and texture segmentation. However, they have a disadvantage
not to perform well in case of a rotated image because of its direction-oriented filter.
This paper proposes a method of extracting local texture features from blocks with central
interest points detected in an image and a rotation invariant Gabor wavelet filter. We also propose
a method of comparing pattern histograms of features classified by VQ (Vector Quantization)
Keyword : Image retrieval, texture, rotation invariant Gabor filter, VQ, interest points.
