A Novel Compression Technique for Super Resolution Color Photography

A novel paradigm for super-resolution color image compression is introduced that combines space-domain and frequency-domain color image processing operations. In the space domain, image color-brightness separation is exploited, and in the frequency domain, spectral properties of the Fourier magnitude and phase of the digitally-acquired image are exploited. Working in both domains concurrently allows for afresh new approach to super-resolution image compression that addresses both issues of quality and reduced storage size. Experimental results as well as empirical observations show that our technique is very competitive with the widely used JPEG image compression standard with the added advantage of being able to recover the original quality without any degradations common in lossy compression techniques
