What is peak detection algorithm?

A new automatic peak detection algorithm is developed and applied to histogram-based image data reduction (quantization). The algorithm uses a peak detection signal derived either from the image histogram or the cumulative distribution function to locate the peaks in the image histogram.

How do you find a peak in a signal?

A common requirement in scientific data processing is to detect peaks in a signal and to measure their positions, heights, widths, and/or areas. One way to do this is to make use of the fact that the first derivative of a peak has a downward-going zero-crossing at the peak maximum.

How does SciPy signal Find_peaks work?

Find peaks inside a signal based on peak properties. This function takes a 1-D array and finds all local maxima by simple comparison of neighboring values. Optionally, a subset of these peaks can be selected by specifying conditions for a peak's properties.
