Secure distributed data storage can shift the burden of maintaining a large number of files from the owner to proxy servers. Proxy servers can convert encrypted files for the owner to encrypted files for the receiver without the necessity of knowing the content of the original files. In practice, the original files will be removed […]
Medical image enhancement using resolution synthesis
We introduce the bilateral filter BF is the same bilateral filter we use in the HSF for improved resolution synthesis For picture blocks, BR(Bayesian reconstruction) simply uses the conventional JPEG decoder to decode the blocks. RS is a classification based image interpolation scheme which achieves optimal interpolation by training from image pairs at low resolution […]
Co-distribution patterns Mining for Maximum crime datasets
Crime activities are geospatial phenomena and as such are geospatially, thematically and temporally correlated. We analyze crime datasets in conjunction with socio-economic and socio-demographic factors to discover co-distribution patterns that may contribute to the formulation of crime. We propose a graph based dataset representation that allows us to extract patterns from heterogeneous areal aggregated datasets […]
