A Comparison of Haar Wavelets and Kekre’s Wavelets for Storing Colour Information in a Greyscale Image

Storage of Colour Information in a Greyscale Image using Haar Wavelets and Various Colour Spaces

The technique of embedding colour information in a greyscale image such that the original colour image can be reconstructed from this modified greyscale image has previously been proposed using the YCbCr colour space with the improvement using Kekre‟s LUV colour space. The embedding of the colour information into the greyscale image leads to the formation of a slightly distorted greyscale image...

A Haar wavelets approach to Stirling's formula

This paper presents a proof of Stirling's formula using Haar wavelets and some properties of Hilbert space, such as Parseval's identity. The present paper shows a connection between Haar wavelets and certain sequences.

Haar Basis Wavelets

The Haar transform, which is one of the earliest transform functions proposed, was proposed in 1910 by a Hungarian mathematician Alfred Haar. It is found effective as it provides a simple approach for analysing the local aspects of a signal. Say we start with an image slice (one dimensional) of size , so we can write the image as Recursive Process of Decomposing an Image in terms of Sums and Di...

Generalized Haar Wavelets and Frames

Generalized Haar wavelets were introduced in connection with the problem of detecting specific periodic components in noisy signals. John Benedetto and I showed that the non–normalized continuous wavelet transform of a periodic function taken with respect to a generalized Haar wavelet is periodic in time as well as in scale, and that generalized Haar wavelets are the only bounded functions with...
