Shape Regularized Active Contour Using Iterative Global Search and Local Optimization
Recently, nonlinear shape models have been shown to improve the robustness and flexibility of segmentation. In this paper, we propose Shape Regularized Active Contour (ShRAC) that...

Two Novel Iterative Joint Frequency-Offset and Channel Estimation Methods for OFDMA Uplink
—We address joint estimation of frequency offsets and channel responses in OFDMA uplink. A cyclically equal-spaced, equal-energy interleaved pilot preamble is proposed by which t...

Generalized Iteration and Coiteration for Higher-Order Nested Datatypes
Abstract. We solve the problem of extending Bird and Paterson’s generalized folds for nested datatypes and its dual to inductive and coinductive constructors of arbitrarily high ...

Pure Pointer Programs with Iteration
not use pointer arithmetic. Such "pure pointer algorithms" thus are a useful abstraction for studying the nature of logspace-computation. In this paper we introduce a for...
