Further, we optimized our proposed dictionaries based on KSVD algorithm and measured the performance of dictionaries using orthogonal matching pursuit (OMP) and basis pursuit (BP). The result showed that the Dictionary based on Discrete Tchebichef Transform (DTT) performed better as compared to the dictionary based on Discrete Cosine Transform (DCT). The proposed transform is first time introduced to made comparison with the DCT based dictionary generation. The proposed dictionaries are predetermined and optimize using KSVD algorithm. The accuracy will be increase with the slight increase of the computation complexity using Discrete Tchebichef Transform as compared to the Discrete Cosine Transform. The root mean square values are used to measure the accuracy. © 2015 IEEE. date: 2015 publisher: Institute of Electrical and Electronics Engineers Inc. official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84963700679&doi=10.1109%2fICSPCS.2015.7391776&partnerID=40&md5=29cb12957d3d8322b8544491c3d2513a id_number: 10.1109/ICSPCS.2015.7391776 full_text_status: none publication: 2015, 9th International Conference on Signal Processing and Communication Systems, ICSPCS 2015 - Proceedings refereed: TRUE isbn: 9781467381185 citation: Qayyum, A. and Malik, A.S. and Nuafal, M. and Iqbal, M. and Abdullah, T.A.R.B.T.
