The use of different digital devices is increasing every day.Thus it is necessary to compress images to make efficient transfer and storage of data.Wavelet is the image compression algorithm.It is Discrete Wavelet Transforms (DWT).Wavelet algorithms can process data at different scales or resolutions.The different wavelets used for image compression are Haar, Daubechies, Biorthogonal and Symlet.This paper presents a comparative study of various wavelet families for image compression and tests the results in terms of compressed image quality.The results are measured in terms of MSE, PSNR, CR and Elapsed time for compression considering as subjective quality measures.
