Implementation Of DCT and IDCT Technique On Image Compression Using VHDL Projects main idea is to develop a efficient compression method for images. DCT is a efficient mathematical method which can convert data from amplitude representation to frequency representation. As DCT is one of the mostly used method for filtering, multiplexing , speech coding and image coding. 2D DCT is mostly used in image compression. This is also used in telephone coding schemes.
DCT compression technique will be perfect for image compression because of it energy compaction property. In most of the images energy is concentrated at low and middle frequencies and middle frequency is visible for a normal human eye .
