Search Space Partitioning Using Convex Hull and Concavity Features for Fast Medical Image Retrieval
A new approach is presented for partitioning an image database by classifying and indexing the convex hull shapes and the number of region concavities. The result is a significant...

Mining distance-based outliers from large databases in any metric space
Let R be a set of objects. An object o R is an outlier, if there exist less than k objects in R whose distances to o are at most r. The values of k, r, and the distance metric ar...

Asymptotic Analysis of Space-Time Codes in Non-Gaussian Noise and Interference
— In this paper, we provide a framework for the asymptotic performance analysis of space–time codes (STCs) in correlated Ricean fading and non–Gaussian noise and interference...

A New Hybrid Space-Time Block Codes and Spatial Multiplexing Scheme with Precoding
— We present a new hybrid scheme which combines space-time block codes (STBC) and spatial multiplexing (SM) to achieve both diversity and spatial multiplexing gain. We design a n...
