Dr. H. B. Kekre, Sudeep D. Thepade, Adib Parkar . Article:A Comparison of Haar Wavelets and Kekreís Wavelets for Storing Colour Information in a Greyscale Image. International Journal of Computer Applications. 11, 11 ( December 2010), 32-38. DOI=10.5120/1625-2186
Abstract
The technique to store colour information within a greyscale image has been proposed previously using various colour spaces, such as the YCbCr, LUV, YCgCb, YUV, and YIQ colour spaces, and using the Haar wavelet transform. One such study is described in [1]. This research paper extends the study to another wavelet transform – Kekre’s wavelet transform (abbreviated as KWT). The embedding of the colour information into the greyscale image leads to the formation of a slightly distorted greyscale image known as a “matted greyscale” image. This matted greyscale image is used to reconstruct the colour image.
