    Illumination Compensation Using OLHE and it's Application to Face Recognition
    (2016-08-23T11:00:15Z) Ramya, R; R Shwetha, Prasad; Abiramy, D
    Illumination compensation and normalization play a crucial role in face recognition. The existing algorithms either compensated low-frequency illumination, or captured high frequency edges. However, the orientations of edges were not well exploited. In this paper, we propose the orientated local histogram equalization (OLHE) in brief, which compensates illumination while encoding rich information on the edge orientations. We claim that edge orientation is useful for face recognition.

    Secure Data Dissemination Using Multi-Hop Cluster Based Hybrid Architecture in VANET
    (2016-07-13T06:13:39Z) Ramya, R
    Communication methods based on VANET are generally focused on IEEE 802.11p-WAVE standards. There are two issues in such communication at high and low vehicular densities namely disconnection of networks and broadcast storm. A pure cellular technology is not feasible. Hybrid architecture with the combination of LTE and IEEE 802.11p is proposed named as VMASc-LTE is clustering based algorithm. Members of the cluster are connected to its head through direct connection using IEEE 802.11p communication standard but cluster head will communicate with eNodeB using LTE connection. The proposed system shows better performance and it is more efficient than previously proposed algorithms.
