## Fast Fourier transform (FFT) source program

The source program I wrote is based on MATLAB platform, but its idea is based on C + +, because MATLAB has its own fast Fourier transform (fft) function. I didn't understand the operation principle of fft in MATLAB, so I wrote a source program.
The theoretical knowledge of FFT can refer to the contents of these bloggers< ht ...

## Image Enhancement (1-Gray Level Transform) - Intensive MATLAB Source Code

Starting with three questions:
First question: What is the enhancement of digital images?
Personal understanding is that by smoothing and denoising the image, changing the gray level or enhancing the edge, we can show some image features we want more clearly. This is image enhancement, which focuse ...
