You don't need to be Einster to Understand Wavelets!!!

[amabosses]

Brilliant,

Here is an explanation on wavelets!!!!!!!!!! Forget about those who discourage because they are lost with what you are talking about!!

Wavelets are functions that satisfy certain requirements. The name wavelet comes from the requirement that they should integrate to zero, "waving" above and below the x-axis.

They find applications in Telecommunications because inlike fourier transforms which are only localised in the freuency domain, wavelets are localised both in time and frequency domain. I am sure you can now follow as to why they find several applications in telecommunications!!

Bye for now and more when you will appear. Continue the spirit Brilliant. This is the only way the country can improve and not SEX everytime you open bwanji>

um.... who is Einster?

M_Sata good to hear such intelectual contributions from you. indeed people like Brilliant need our support and help. 4sure, such are likely to turn round the current painting of Zambia.

Suga09, looks like there is a spelling error on Einster. It probably has to read Einstein! Just curious also, is Suga... supposed to read Sugar # 9?

On wavelet theory;

Suppose you want to produce a discretely sampled image from a continuous
function. You would do this by effectively `scanning' the function using a
sinc function [ sin(x)/x ] `aperture'. You can do the same thing starting with a high resolution discretely sampled image. You can then get a whole set of images showing the edges at different resolutions by differencing the image at one resolution with another version at another resolution. If you have made this set of images properly they ought to all add together to give the original image.

This is an expansion of data. Suppose you started off with a 1K*1K image.
You now may have a 64*64 low resolution image plus difference images at 128*128, 256*256, 512*512 and 1K*1K.

Where has this extra data come from? If you look at the difference images you will see there is obviously some redundancy as most of the values are near zero. From the way we constructed the levels we know that locally the average must approach zero in all levels but the top. We could then construct a set of functions out of the sync functions at any level so that their total value at all higher levels is zero. This gives us an orthonormal set of basis functions for a transform. The transform resembles the Haar transform a bit, but has symmetric wave pulses that decay away continuously in either direction rather than square waves that cut off sharply. This transform is the wavelet transform ( got to the point at last!! ).

These wavelet functions have been likened to the edge detecting functions
believed to be present in the human retina.

This is what I wanted!!! A discusion that is academic biased and not sex time and again!! Thank you M_Sata and g#la_fj, for the contribution.

Your explanations really make a lot of sense!!! I wondered how an Angle-Diversity receiver with wavelet analysis per receiving element would greatly increase power-efficiency and render a robust diffuse infrared sysetm under heavy shadowing and and intersymbol interference, but I now understand.

Guys, this forum, in my views can be used for many things, for rubbish or even for the education purposes. I feel encouraged by M_Sata who can encourage me and tell me to go ahead with such topics. Thanks g#la_fj, please lets keep the spirit. Those that are interested in rubbish can go ahead and those of us not interested in SEX topics can concetrate on serious issues.

how dare thee spell my hubby's name ERRORLY muahahhahahhaha...off with his hiiiiid (a.ka. head). >.<!

[Vimbling]

I know that only a person who lacks understanding of Science can fail to correct the error made by the big man M_Sata. To those far from science, the man wanted to write Einsten, but people who can't analyse issue would rather analyse spellings since they can follow his explanations. I wish Suga09 commented on the details in the message that was carried in the information on wavelet theory and not spellings!!!!

Bassop M_Sata is learned!!!!

Brilliant,

We support your endevours to paint a positive image of our beloved nation.

But remember, you are known by the company you keep. Yours is Bwanji at present!!
lol!!

Thank you cho for your comment, but I seem to have been left behind. I dont really understand what you mean when you say

But remember, you are known by the company you keep. Yours is Bwanji at present!!
lol!!

Can you kindly do me a favour and explain more on that?? Thanks

[sexysugar]

um.... who is Einster?
yea.

Brilliant,

Getting people to share your world view is a risky venture. Right now your presence at Bwanji is not developing you as a person. You are not learning anything here and it is probably questionable on whether you are spending your time wisely. In short, you are having to be like the crowd you wish to change.

However, if you do succeed it would have been worth while. If you succeed.

If you don't succeed, it would have been a waste of your time. I have learnt with age that as you get older time becomes more valuable than money. I think when the Lord comes his first question will be "how did you spend your TIME"?

The question for you constantly as you seek to change Bwanji is "Am I spending my time wisely?".

As I said, I support what you trying to do for Zambia. But you are also an individual - so think of what is important for you first! It may not be worth worsting time educating these guys.
