Widespread use of digital imagery has resulted in a need to manage large collections of images. Systems providing query by example (QBE) capability offer improved access to contents of image libraries by retrieving matches to a query image. Texture is an important feature to consider in the matching process. However, standard approaches often employ a(More)
Image segmentation can be viewed as the process of classifying regions in a picture into groups with common properties (i.e. texture). A difficulty arising is that common texture can be classified differently when viewed at different scales and rotated viewpoints. This paper presents a feature vector based on the DT-CWT (dual-tree complex wavelet transform(More)
