Polar Codes With Higher-Order Memory
We introduce the design of a set of code sequences tC n : n ě 1,m ě 1u, with memory order m and code-length N “ Opφq, where φ P p1, 2s is the largest real root of the polynomial equation F pm, ρq “ ρm ́ρm ́1 ́1 and φ is decreasing in m. tC n u is based on the channel polarization idea, where tC n u coincides with the polar codes presented by Arıkan in [1] and can be encoded and decoded with comple...
متن کاملScale Invariant Face Detection Method Using Higher-Order Local Autocorrelation Features Extracted from Log-Polar Image
This paper proposes a scale invariant face detection method which combines higher-order local autocorrela-tion (HLAC) features extracted from a log-polar transformed image with Linear Discriminant Analysis for \face" and \not face" classiication. Since HLAC features of log-polar image are sensitive to shifts of a face, we utilize this property and develop a face detection method. HLAC features ...
متن کاملScale and Rotation Invariant Recognition Method Using Higher-Order Local Autocorrelation Features of Log-Polar Image
This paper proposes a scale and rotation invariant recognition method which uses higher-order local autocorrelation (HLAC) features of log-polar image. Linear scalings and rotations are represented as shifts in the log-polar image which is obtained by re-sampling of the input image. HLAC features of log-polar image become robust to the linear scalings and rotations of a target because HLAC feat...
متن کاملNuclear Organization of Mammalian Genomes: Polar Chromosome Territories Build Up Functionally Distinct Higher Order Compartments
We investigated the nuclear higher order compartmentalization of chromatin according to its replication timing (Ferreira et al., 1997) and the relations of this compartmentalization to chromosome structure and the spatial organization of transcription. Our aim was to provide a comprehensive and integrated view on the relations between chromosome structure and functional nuclear architecture. Us...
