I have a current implementation of Gaussian Blur using regular convolution. It is efficient enough for small kernels, but once the kernels size gets a little bigger, the performance takes a hit. So, I
I\'m pretty new to Image Processing and found out that the FFT convolution speeds up the convolution with large kernel sizes a lot.
I have been spending quite a bit of time studying FFT\'s.I am in particular interesting in using KISSFFT because it is a very portable C implementation.
My goal is to compile the kiss_fft libraries to use in JNI for android development. However to begin with, I am attempting to just use the kiss_fft libraries on my linux machine in C.
