Improving Discrete Cosine Transform performance using Intel(R) Cilk(TM) Plus

DCT and Quantization are the first two steps in JPEG compression standard. This article demonstrates how DCT and Quantizing stages can be implemented to run faster using Intel® Cilk™ Plus. In order to see the effect of quantization on the image, the output of Quantization phase is passed on to the de-quantizer followed by Inverse DCT and stored as an output image file.

  • Intel® IPP - Unified Image Codecs(UIC)

    The UIC is introduced in the Intel IPP version 6.0 and it standardized the interface of the image codecs support in Intel IPP and make ease of use for image compression and more threading performance improvements.
