Implementation of DCT and Fractal Compression Technique

Digital images are required in various sectors and it requires a large data set to depict them, their transmission and storage mechanism is time-consuming. The information in the photos is optimized by extracting only fundamental signals to displays the visible portions. The storage and transmission costs are often reduced by compression. During image compression, graphics file size is decreased in bytes without compromising the image's quality beyond an acceptable level. Methods like DCT, DWT, etc. are used for image compression. Blocking artifacts are contains by this compression technique. To overcome this challenge and compress the image efficiently, hybrids of DCT and fractal compression techniques were created. Because DCT is utilized for color image compression, fractal compression is used to avoid repetitive compression of comparable blocks. The PSNR, SSIM, and Compression ratios are considered to analyze their effects.
