ABSTRACT
JPEG2000 is a image-coding standard developed for compression of any image. JPEG 2000, which provides a higher compression ratio than the traditional JPEG, is an upcoming compression standard for still images. The JPEG2000’s algorithm is based on Discrete Wavelet Transform (DWT) and the Embedded Block Coding with Optimal Truncation (EBCOT). Both algorithms are computationally intensive and require significant memory. We propose a new coding with Fibonacci numbers to compress losslessly the scalar quantized and DWT coefficients. We present a coding scheme based on Fibonacci numbers in the place of EBCOT in JPEG2000. We prove that Fibonacci code gives better results.
