normal 0 false false false en-us x-none ar-sa digital breast tomosynthesis (dbt) is a technology that creates three dimensional (3d) images of breast tissue. tomosynthesis mammography detects lesions that are not detectable with other imaging systems. if image reconstruction time is in the order of seconds, we can use tomosynthesis systems to perform tomosynthesis-guided interventional procedur...

An extended set of Haar-like features for image sensors beyond the standard vertically and horizontally aligned Haar-like features and the 45o twisted Haar-like features are introduced. The extended rotated Haar-like features are based on the standard Haar-like features that have been rotated based on whole integer pixel based rotations. These rotated feature values can also be calculated using...

A novel algorithm for solving in parallel a sparse triangular linear system on a graphical processing unit is proposed. It implements the solution of the triangular system in two phases. First, the analysis phase builds a dependency graph based on the matrix sparsity pattern and groups the independent rows into levels. Second, the solve phase obtains the full solution by iterating sequentially ...
