Graduate How can we determine phase information using Window Fourier Transform?
@rbj...There is not any specific reason for using Gaussian window but in my case i found it easy to make and also my teacher wants to use this, but i am flexible to use any other if good reasons are there for using them. Thanks for the offer of IEEE but i can access IEEE from my university...- hamidlukhnowi

Graduate How can we determine phase information using Window Fourier Transform?
@PhilDSP, thanks for the informative reply. As u mentioned "One thing is that as you shorten the length of the data window the resolution of the FT deteriorates". I am not shortening the length of the data window, i am just multiplying an outside window with my input data. the size of the data...- hamidlukhnowi

Graduate How can we determine phase information using Window Fourier Transform?
Thanks PhilDSP for the reply. Yeah sure next time i will take care about the name. Actually i want to apply the window not to the whole input image, rather just on some part and then from that i want to retrieve the information of phase. Let suppose my input is 128*128 and my window size is...- hamidlukhnowi

Graduate How can we determine phase information using Window Fourier Transform?
First Of all sir thanks for your reply. By window Fourier transform,i meant Short term/time Fourier transform. And Window Fourier transform is mentioned by Kemao Qian in many of his publications. Yeah my case is that i am applying a window whose size is smaller than the input data. Now i want...- hamidlukhnowi

Graduate How can we determine phase information using Window Fourier Transform?
Hello Everyone, Actually my question is related to Window Fourier transform (WFT). I have studied that with the help of WFT we can easily determine the phase of the image. Like by multiplying the window to only a specific part of the input and considering the outside part of the window equals...- hamidlukhnowi
