Description: We propose a new vector formulation of STFT.
We derive a family of inverse STFT estimators and a least
squares one. We discuss their relationship and compare their
performance with respect to both additive and multiplicative
modifications to STFT. The influence of window, overlap, and
zero-padding are investigated as well.

Description: 把一个256*256的图像分成8*8小块，然后进行DFT变换，分别比较在空间域和频域内对图像进行二次抽样和差值最后得出的图像比较-1. Get a grey level image which size is N*N. (For example, 256*256, however,
N = ), and partition to 8*8 sub images.
2. Apply DFT to these sub images, and get the fourier transformed image F.
3. Derive the proper subsampling function matrix S in spatial domain.
4. Multiplying proper 4*4 DFT matrix T to matrix S, derive the frequency version
of subsampling function matrix, S.
5. Similarly, derive the frequency version of interpolation matrix, I.
6. Apply these matrices to each sub image of F (which is DFT of original image),
and get the final image, taking inverse DFT.
7. Apply subsampling/interpolation function matrix S/I to original image in spatial
domain and get the final image.
8. Compare the results from 6, 7.

Description: Displays a rotatable and scaleable wire frame of any
3D mathematical function. This can be made up from the
normal VB maths plus inverse and hyperbolic functions.
Functions can be created and saved as wanted. Image vertices
can also be saved for use elsewhere.
The MS ScriptControl Eval function simplifies calculations
enormously and its use is demonstrated. Also shown are
MoveToEx, LineTo which are much faster than the VB
equivalents and very easy to use. Included are a set of string
handling subroutines such as count characters, squeeze out
spaces, replace sub-strings etc. Commented throughout
including the 3D maths and perspective methods. All the
files are visible and the program is written for an 800x600
screen.
