By reducing the precision of the DCT transformed values using quantization, the number of bits needed to represent the image can be reduced substantially.

Its a free book with low math which will enable you to get DSP very fast.
but you must read the full book with effort
median filter is nothing but selecting the median of 5 data samples
example
In = [3 7 8 1 4]
out = median(in)
where median(in) = sort the data is acending order and selecte the In(3) = the middle element
so median(in) = middle ( [1 3 4 7 8] )'
out = 4
its simple just the median...
In any DSP algo chain where FFT is used ,its usually the real fft with real input - complex twiddles and complex output.
Now since u have a real input (N)...You can use a N/2 point complex FFT and then u can unpack again to N point real output.
N Real input -> N/2 point cmplx FFT -> N/2...
digital image processing project
pyton image + radon transform + inverse radon with recursive method usinf 1d fft projection using matlab will be a nice midsize project....
try get some info of wat i have told ..do some research and u will have a good DIP proj with MRI images.
hope it helped u
about convolution
convolution is a mathematical operator which takes two functions f and g and produces a third function that in a sense represents the amount of overlap between f and a reversed and translated version of g. A convolution is a kind of very general moving average, as one can see...
fourier series
The Fourier series is a mathematical tool used for analyzing periodic functions by decomposing such a function into a weighted sum of much simpler sinusoidal component functions sometimes referred to as normal Fourier modes, or simply modes for short. The weights, or...
As u know the FFT results in a complex domain values...and the real part is the magnitude of the frequency spectrum and the imag part is the phase diffrence..
so while ploting the FFT ..u dont need the imag part...so taking a (abs) gives the magnitude part of the freq spectrum...and u use the...
cc studio
Put the CD in the drive
and install It FIRST :D
if u have use some other IDE's such as Visual studio,VC++ ,eclipse...then CCS doesnt look very diffrent..its just a good IDE.
Read the 'Getting started with CCS' pdf
