The paper addresses the problem of gender classification from face images. For feature extraction, we propose discrete Overlapping Block Patterns (OBP), which capture the characteristic structure from the image at various scales. Using integral images, these features can be computed in constant time. The feature extraction at multiple scales results in a high dimensionality and feature redundan...

the nayband strike-slip fault forms the western margin of the micro-continental lut block in eastern iran. neogene and quaternary mafic volcanic rocks collected near tabas, along the northern part of the fault (nnf; 15 ma), and further to the south, along the middle part of the fault (mnf; 2 ma), are within-plate sodic-series alkali olivine basalts with high tio2 and up to >16% normative nephel...

A method is proposed which aims to reduce the hardware in FPGA-based circuits of Mealy finite state machines (FSMs). The a type structural decomposition method. Its main goal reducing number look-up table (LUT) elements FSM compared three-block circuit. idea using codes collections outputs for replacing inputs and variables. interstate transitions are defined generated two adjacent cycles synch...

Binary field multiplication is the most fundamental building block of binary field Elliptic Curve Cryptography (ECC) and Galois/Counter Mode (GCM). Both bit-wise scanning and Look-Up Table (LUT) based methods are commonly used for binary field multiplication. In terms of Side Channel Attack (SCA), bit-wise scanning exploits insecure branch operations which leaks information in a form of timing ...

This paper presents a method for operational testing of a memristor-based look-up table (LUT) memory block. In the proposed method the deterioration of the memristors (as storage elements of a LUT), is modeled based on the reduction of the resistance range, a phenomenon well known as reported in the technical literature. A quiescent current technique is used to diagnose the memristors when dete...

Data embedding mechanism used for authentication applications should be secure in order to prevent an adversary from forging the embedded data at his/her will. Meanwhile, semi-fragileness is often preferred to allow for distinguishing content changes versus non-content changes. In this paper, we focus on jointly enhancing the robustness and security of the embedding mechanism, which can be used...

Most FPGAs use an array of identical logic blocks, largely because such devices are easy to design. Previous studies on logic block architecture, however, have concluded that while 4-input lookup tables (4-LUTs) make eecient use of area Rose90] Koul92], signiicantly more coarse-grain blocks such as 5-LUTs, 6-LUTs and 7-LUTs are superior in terms of system speed Koul91] Sing91] Sing92]. These re...

introduction the investigated area is situated in the south west of the khorasan razavi province along the north west of the lut block. different types of metal ore bodies along with non-metal deposits have already been documented in the lut block (karimpour et al., 2008). most of the study area is covered with granitoid rocks. metamorphic rocks with unknown age are present in the north of the ...
