Brought up in a pure environment surrounded b mountains and oods.

????????

I deem mlf as a luk person born ith natural gifts Some of them

????????

are "ordinar", shoed obviousl on math, musi and memor at a

????????

quite earl age and ontinued to rve as parts of m

??????

distintiveness as I gre up some of them are "extraordinar ",

????????

for example, m original interest in philosoph. It is hard to

???????

believe to some that hat I have speulated about at the age of

????????

five oinided ith some of the thoughts in Jean-Paul Sartre's

????????

"L'Etre at le Neant".

??

Wh eletronis?

??

It still remains a mster to me ho I left hildhood dream of bee

????????

an astronomer and hose eletroni engineering as m ollege major

????????

instead. Not knoing muh about iruits as about stars at that time.

????????

I emed to be simpl allured b the idea of designing a guidane

????????

sstem for the spae shuttle. Five ears of inquir into the

???????

eletroni orld proved that m hoie as right. I as pletel

???????

infatuated ith suh a field-so profound and vigorous that one is

????????

onl limited b hisher imagination.

????

What's done?

??

Anxious to find out hat "eletronis" reall means. I began doing

????????

laborator rearh as earl as from the third ear. First at the

???????

Miroave Lab, doing iruits simulation and ur interfae design.

????????

Generall speaking. Works during that period ere fragmentar ,

????????

but the have given me suffiient experiene on C. C++, Windos

???????

programming and interfae design, hih laid a sold foundation for

????????

m future stud.

??

Later, to explore something ne, I applied to join the Multimedia

????????

Lab, an "interative "plae sponsored b Prof Xing Li, I beame

????????

familiar ith UNIX sstem and did X Windos interfae design

???????

for some time Probabl beau some interesting points in m design,

????????

I as offered an opportunit b Prof Li to join the "avelet rearh

????????

group". Intending to develop avelet appliations .

???????

That as a turning point in m ork. Wavelet is a brand-ne area

???????

ith modern mathematial bakground, free spae of imagination and,

????????

a little but philosophial olor that totall interested me I

????????

arried out a experiment of appling Embedded. Zero

??????

tree Wavelet algorithm to speeh oding EZW algorithm as

???????

originall developed in image oding, aiming at the

??????

multi-resolution transmission of pitures. Its effiien greatl

????????

depends on the amount of zerotrees the soure produed . B properl

????????

quantized, speeh samples an be expeted to generate a

??????

onsiderable number of zerotrees due to its spetrum

???????

harateristis . In m experiment, different kinds of speeh soures

????????

have been tested and an average pression ratio of 8 I as ahieved,

????????

ith no pereptible distortions Compared ith previous oding

???????

methods, the result is enouraging, for the benefits are gained

????????

through a rather oni proedure doing enoding and deoding is

????????

as shematiall as doing a ross -ord puXXle Moreover. What I have

????????

done is atuall superfiial. There still exist at

??????

least several means to improve it, for example, the appliation

????????

of non-even quantizer, avelet paket, the definition of a higher

????????

dimensional struture like "zeroforest ". the letion of an

???????

appropriate avelet ba, et.. The improvement of the algorithm

????????

is inluded in m present rea's on going

??????

I am no orking on m diploma thesis. The topi is "A Rearh of

????????

Multi-resolution Coding of information and Relevant

??????

Transmission Protools", inluding multi-resolution oding of

????????

images. Wavelet oding of audio signals , and an integrated demo

????????

sstem.

Speial interest

??

More than enjoing the oding game, another fasinating point I

????????

found in speeh or image proessing is the bination of signal

????????

theor ith neuropsolog and ognitive siene. It as disovered as

???????

I as studing the auditor model. When a ries of plex

???????

phsiologial funtions are modeled and mathematiall abstrated ,e

????????

found out that the ohlea is atuall a living avelet filter, hile

????????

lumps of ells orking infatiguedl for the Fourier Transform--the

????????

a the hearing ortex to grasp a sound Some interesting things an

????????

be also found in our visual sstem The ontour and texture bad

????????

image oding is one of the inspirations given b our on ees, and

????????

is just one of the numerous that aiting for us to disover When e

????????

are puXXled b piles of questions suh as sound and vision,

???????

pereption and ognition, h don't e go to the Creator and ask ho

????????

he has handled them?

??

What to pursue?

??

Conluded form above, m rearh experienes onentrate on speeh

????????

and image proessing, ith an emphasis on oding shemes and

???????

a speial interest on the appliation of knoledge in biologial

????????

and ognitive siene. What I am going to do is to develop m

???????

interest on speeh or image proessing, preferabl ith an

???????

interdisiplinar approah. Beau of the rapid advanes and the

????????

ative environment of suh a field in the United States. I am sure

????????

that an institution ith a orld reputation on

?????

eletrial engineering like ours is m first hoie. Hoever ,due to

????????

m broad interest in eletronis and other branhes of learning,

????????

there is alas no limitations on speifi programs.

??????

Still further

??

Upon reeiving a dotoral degree in the States, I ill go bak to m

????????

mother ountr, not onl for the beloved land and people, but also

????????

for the temptation of eastern philosoph. The idea hit upon

???????

me hen I aught sight of the graphi of avelet deposition that

????????

is surprisingl similar to the anient Taoist interpretation

???????

of the generation of universe . It has been idel aepted that

????????

eastern thought ould pla an important role in future siene and

????????

I believe the instillation of modern estern ideas ould aelerate

????????

the proess. As the dendant of the Orient. I am illing to make

????????

some useful attempts.
