SAD PROCESSOR FOR MULTIPLE MACROBLOCK MATCHING IN FAST SEARCH VIDEO MOTION ESTIMATION

Publikováno v: ICTACT Journal on Image and Video Processing, Vol 5, Iss 3, Pp 966-972 (2015)

Motion estimation is a very important but computationally complex task in video coding. Process of determining motion vectors based on the temporal correlation of consecutive frame is used for video compression. In order to reduce the computational c

Hardware Efficient Architecture with Variable Block Size for Motion Estimation

Autor: Nehal N. Shah, Harikrishna Singapuri, Upena D. Dalal

Publikováno v: Journal of Electrical and Computer Engineering, Vol 2016 (2016)

Video coding standards such as MPEG-x and H.26x incorporate variable block size motion estimation (VBSME) which is highly time consuming and extremely complex from hardware implementation perspective due to huge computation. In this paper, we have di

Computational complexity reduction in HEVC intra prediction using dual tree complex wavelet transform and holoentropy

Autor: Swati Vinod Sakhare, Upena D. Dalal

Publikováno v: ASIAN JOURNAL OF CONVERGENCE IN TECHNOLOGY. 6:16-27

High efficiency video coding (HEVC) is the newest video codec to increases the coding efficiency of its ancestor H.264/Advance Video Coding at the cost of highly increased computational complexity. In this paper, a novel method using Dual tree Comple

High efficiency coding for surveillance videos based on selective based fast intra coding

Autor: Upena D. Dalal, Swati Vinod Sakhare

Publikováno v: Multimedia Tools and Applications. 79:14079-14101

HEVC, the successor of popular H.264 video compression standard targets the new era of ultra high-resolution videos with higher frame rates. Lossless coding mode of high-efficiency video coding (HEVC) relies on efficient intra prediction methods for

Decentralized Context Aware Access Control Model for Internet of Things

Autor: Devesh C. Jinwala, Upenda D. Dalal, Shivanshu Mehta, Dhiren Patel

Publikováno v: Journal of Computational and Theoretical Nanoscience. 17:162-171

Access control mechanisms are a primary security requirement in Internet of Things applications. Traditional access control mechanisms are inefficient while applying directly to IoT applications. Various proposals have been made to adapt traditional

The Incidence and Risk Factors of De Novo Skin Cancer in the Liver Transplant Recipients

Autor: JM Modaresi Esfeh, M Pagadala, R Lopez, A Tabba, D Dalal, IA Hanouneh, B Eghtesad, NN Zein

Publikováno v: International Journal of Organ Transplantation Medicine, Vol 3, Iss 4, Pp 157-163 (2012)

Background: Liver transplantation (LT) increases the risk of de novo malignancies including skin cancers. However, risk factors for this type of cancers have not been well studied.Objective: To determine the incidence of skin cancer in LT recipients,
