ABSTRACT:
In this paper image quality of two types of
compression methods, wavelet based and seam carving based are investigated. A
metric is introduced to compare the image quality under wavelet and seam
carving schemes. Meyer, Coiflet 2 and Jpeg2000 wavelet based methods are used
as the wavelet based methods. Hausdorf distance based metric (HDM) is proposed
and used for the comparison of the two compression methods instead of model
based matching techniques and correspondence-based matching techniques, because
there is no pairing of points in the two sets being compared. In addition
entropy based metric (EM) or peak signal to noise ration based metric (PSNRM)
cannot be used to compare the two schemes as the seam carving tends to deform
the objects. The wavelet compressed images with different compression
percentages were analyzed with HDM and EM and it was observed that HDM follows
the EM/PSNRM for wavelet based compression methods. Then HDM is used to compare
the wavelet and seam carved images for different compression percentages. The
initial results showed that HDM is better metric for comparing wavelet based
and seam carved images.
