Quasi-Lossless Based Fractal Image Compression Using Krill Herd Algorithm
International Journal of Advanced Trends in Computer Science and Engineering · 2020
Image compression techniques based on fractals produces good quality of image.It makes use of different techniques to compress images and to provide better solution.One such technique is quasi lossless fractal image compression.This paper focuses on Krill Herd (KH) algorithm to enhance the quasi lossless fractal image compression method.It deals with various parameters such as time taken for encoding and decoding, compression ratio, quality and retrieved image, Peak Signal to Noise Ratio (PSNR) value.Applying Krill Herd algorithm to quasi lossless fractal image compression yields better image quality of image and provides high Compression Ratio (CR).The different images concerning compression parameters and their performances are compared with other optimization algorithms.
