To direct the operation of a computer, we often use a shell, a user interface that provides accesses to the OS kernel services. Traditionally, shells are designed atop an OS kernel. In this paper, we show that a shell can also be designed below an OS. More specifically, we present HYPERSHELL, a practical hypervisor layer guest OS shell that has all of the functionality of a traditional shell, b...

A novel statistical shape model is presented for automatic and accurate segmentation of prostate boundary from 3D ultrasound (US) images, using a hierarchical texture-based matching method. This method uses three steps. First, Gabor filter banks are used to capture rotation-invariant texture features at different scales and orientations. Second, different levels of texture features are integrat...

We introduce a new topological feature representation for point cloud objects. Specifically, we construct a Stochastic Multiresolution Persistent Homology (SMURPH) kernel which represents an object’s persistent homology at different resolutions. Under the SMURPH kernel two objects are similar if they have similar number and sizes of “holes” at these resolutions. Our multiresolution kernel can c...

Background: Replacement of the gluten is one of the challenging issues in the food industry, since producing nutritious and functionally acceptable gluten-free foods is difficult. The cake is a cereal-based product that attracts the consumers due to its various flavors, long shelf-life, and relatively low cost. Considering the competition in markets and the increased demand for functional and n...

Texture synthesis is a necessary component of realistic scene generation. In particular, it is necessary for the simulation of image backgrounds for the testing of automatic target recognizers. We present a synthesis-by-analysis model for texture replication or simulation. This model can closely replicate a given textured image or produce another image which, although distinctly di erent from t...
