| Abstract: | This paper presents a comparative study on image coders using the discrete cosine transform and the discrete wavelet transform, addressing in particular the JPEG-like and the EZW based image coders. We compare and evaluate the JPEG Baseline Image coder (using the DCT), a JPEG-like image coder based on the DWT, and an EZW coder, which is also based on the DWT. Taking into account the differences on the architecture of the coders, we compare them by using the same test images, for approximately the same conditions and characteristics, namely the approximately equal compression ratio. |
