摘要：Digital image processing(DIP) is the use of computer algorithms to perform image processing ondigital images. The basic operation performed by a simple digital camera is, to convert the light energy to electricalenergy, then the energy is converted to digital format and a compression algorithm is used to reduce memoryrequirement for storing the image. This compression algorithm is frequently called for capturing and storing theimages. This leads us to develop an efficient compression algorithm which will give the same result as that of theexisting algorithms with low power consumption. Image compression is useful as it helps in reduction of theusage of expensive resources, such as memory, or the transmission bandwidth required. But on the downside,compression techniques result in distortion and also additional computational resources are required for compressiondecompressionof the medical image data.In this, we proposed DHT based image compression technique. The computational complexity is further reduced byusing pipelined CORDIC architecture for computation of sin and cos terms in DHT. The CORDIC based DHT ispartially simulated and synthesized by using Xilinx ISE design suite and the same was implemented on targeted FPGA.The hardware requirements and gate delay values are observed and noted down.
