There has been an unrestrained growth of videos on the Internet due to proliferation of
multimedia devices. These videos are mostly stored in unstructured repositories which pose …

We present novel algorithms for computing discrete Fourier transforms with high
performance on GPUs. We present hierarchical, mixed radix FFT algorithms for both power …

The aim of a Content-Based Image Retrieval (CBIR) system, also known as Query by Image
Content (QBIC), is to help users to retrieve relevant images based on their contents. CBIR …

With the tremendous growth of ICT (Information and Communication Technology), we are
able to generate, store, share and transfer enormous amount of information. World Wide …

In the pathological diagnosis of early, late and non-membranous nephropathy, direct
immunofluorescence is highly likely to present potentially specific lesions, while it is often …

The focus of this paper is to compare several common machine learning classification
algorithms for Optical Character Recognition of CAPTCHA codes. The main part of a …

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

Content Based Image Retrieval (CBIR) is a process in which for a given query image, similar
images will be retrieved from a large image database based on their content similarity. The …

In this paper, the problem of content based image retrieval in dynamic environment is
addressed. It is not feasible for systems that analyze images in real-time where the images …

Content-based image retrieval is a very important area of research nowadays. Content
Based mage Retrieval (CBIR) is a technique which uses visual features of image such as …
