问题 I'm implementing a peak detection algorithm in Python that detects only those peaks that are above a threshold magnitude. I don't want to use the inbuilt function as I have to extend this simulation to Hardware implementation also. from math import sin,isnan from pylab import * def peakdet(v, delta,thresh,x): delta=abs(delta) maxtab = [] mintab = [] v = asarray(v) mn, mx = v[0], v[0] mnpos, mxpos = NaN, NaN lookformax = True for i in arange(len(v)): this = v[i] if abs(this)>thresh: if this >

A rooted device may be modified in any way, and thus can completely hide

I am trying to make a program which opens an image, scans it for circles/round shapes and returns the coordinates so that I can use the cv.Circle function to draw circles over the circle detected. My question is: How do I get the coordinates/radii of the circles detected in an image using cv.HoughCircles() ? Using this page, I found out how to detect the circles (which took me a lot of time to find out since I don't understand terms like threshold and the OpenCV documentation for Python is really poor, almost none). Unfortunately, on that page it didn't show how to extract the information of
