FPGA Based Hardware Realization of DCT - II Independent Update Algorithm for Image Processing Applications
Dibyayan Das Sharma, Anshu Kumari · 2011
Discrete Cosine Transform (DCT) and Discrete Sine Transform (DST) are two transform compression techniques that are used extensively for data compression, most notably in audio, speech and image processing applications. Several algorithms for computation of DCT and DST coefficients have been developed so far, among which independent update algorithm seems to be the most promising technique for future applications. In this paper, the FPGA implementation of the DCT – II independent update algorithm has been undertaken and its performance is evaluated. Use of the above algorithm for applications like image intelligence, biometric systems, image duplication etc. is also discussed.
