I have a limited system and would like to implement FFT within STM32F103C8 without any extra memory buffers.
So I want to know how many memories are needed to implement if I have 2592x1944x8bit size's one image?
Actually, I want to have a process such as
Origial image ---> FFT ---> Blur ---> IFFT ---> Modified image The blur(Gaussian) size is quite a bit huge size. 60x60~90x90 variable.
What is the memory requirements for FFT on STM32F103C8 ?
The reason of why I pick this way up is 60x60~90x90 gaussian blur need a huge memory to process to blur. and I found FFT blur processing from google, so this is the reason.
