### Does a reentrant list for signal queue in a single-thread environment exist?

I need to handle Unix signals in a single-threaded application with the following goals: Signals doesn't mask on receive (thus, the signal handler must be reentrant). I am not allowed to lose signal ...

### Compare phase and magnitude spectrum results of 2 Images

I have read that from Fourier transform we obtain magnitude and phase spectrum. The magnitude spectrum tells you how strong are the harmonics in a image and the phase spectrum tells where this ...

### Which algorithms are usable for heatmaps and what are their pros and cons

This is a cross post from Stack Overflow, and DSP at Stackexchange since I cannot really decide which part of Stackexchange is most fitting. If this is the wrong place please tell me and I'll remove ...
