TLDR
It is found that Biorthogonal wavelets outperform the orthogonal ones in both the criteria and objectively peak signal to noise ratio and subjectively visual quality of image.Abstract:
e present work we analyze the performance of orthogonal and Biorthogonal wavelet filters for image compression on variety of test images. The test images are of different size and resolution. The compression performance is measured, objectively peak signal to noise ratio and subjectively visual quality of image and it is found that Biorthogonal wavelets outperform the orthogonal ones in both the criteria.

Effect of Symlet Filter Order on Denoising of Still Images
Sarita Kumari,Ritu Vijay +1 more
TL;DR: This paper shows that Sym 5 represents the best results for compression and denoising of natural images and it is analyzed that with increase of filter order PSNR value increases but visual quality of the compressed image degrades rapidly.

Selection of Mother Wavelet For Image Compression on Basis of Nature of Image
TL;DR: Compression performance of Daubechies, Biorthogonal, Coiflets and other wavelets along with results for different frequency images are compared and it is proposed that proper selection of mother wavelet on the basis of nature of images, improve the quality as well as compression ratio remarkably.

Orthogonal vs. Biorthogonal Wavelets for Image Compression
TL;DR: It is demonstrated that biorthogonal and orthogonal wavelets generate similar compression performance when they have similar filter properties and both employ symmetric extension, and that linear (or near-linear) phase filters are critical to compression performance—an issue that has not been recognized to date.
