The paper presents innovative content based image retrieval (CBIR) techniques based on
feature vectors as fractional coefficients of transformed images using DCT and Walsh …

This paper proposes a novel Kekre's Wavelet (KW) transform which is generated from
Kekre's transform. Kekre's Wavelet transform can be used for various applications in image …

The paper discusses novel image retrieval methods based on shape features extracted
using gradient operators and slope magnitude technique with Block Truncation Coding …

Technological advances in digital imaging, broadband networking, and data storage have
motivated people to communicate and express by sharing images, video, and other forms of …

The paper presents the novel hybrid wavelet transform generation technique using two
orthogonal transforms. The orthogonal transforms are used for analysis of global properties …

The paper presents novel Walshlet Pyramid based image retrieval techniques. Here content
based image retrieval (CBIR) is done using the image feature set extracted from Walshlets …

Success of image retrieval depends on performance and speed of the retrieval technique
used. Many techniques have already been proposed for content based image retrieval …

This paper proposes algorithm to generate discrete wavelet transform from any orthogonal
transform. The wavelet analysis procedure is to adopt a wavelet prototype function, called an …
