Improving Discrete Cosine Transform performance using Intel® Cilk™ 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. This article demonstrates how to improve the performance of Discrete Cosine Transforms using Intel® Cilk™ Plus.  To continue reading please click here
