QUESTION

Trying to blur highest variance point of an image but some conversion problem exist in code

Asked 2021-Jun-10 at 20:29

I am trying to blur of highest variance point from the image. I wrote code below. 1st part finds the variance of the image. I checked the resultant variance of an image and it is correct. (I used Lena's image) In 2nd part, I find the highest variance coordinates and send to this Function which finds gaussian blur. When I execute this code, it throws "C:\Tmp\blur_highest_variance.py", line 66, in sigma=15) numpy.core._exceptions.UFuncTypeError: Cannot cast ufunc 'subtract' output from dtype('float64') to dtype('uint8') with casting rule 'same_kind' I tried a few conversions between types but no avail. Can you show me some direction?

The error message tells us the line and the reason for the error:

Traceback (most recent call last):

It is more simple to debug the code using intermediate variables:

Sympy.solve provides "AttributeError"

If sigma[i, j] == 0 or sigma[i, j] == 1 it doesnt matter. It only takes the position of non-zero elements. There is a code that provides finding coeffs y1, y2, w1, w2, which are sympy.symbols, of func f by sympy.solve. C - is a matrix.

Since you weren't providing the information I asked for, I tried to write a small test case, seeking to get at the core of your problem.

Mixing numpy and sympy is tricky and somewhat unpredictable. But sometimes sympy symbols can be used in numpy expressions.

QUESTION

Calculation of the first and third quartile

Asked 2021-Jun-09 at 14:05

I'm trying to calculate the mean, standard deviation, median, first quartile and third quartile of the lognormal distribution that I fit to my histogram. So far I've only been able to calculate the mean, standard deviation and median, based on the formulas I found on Wikipedia, but I don't know how to calculate the first quartile and the third quartile. How could I calculate in Python the first quartile and the third quartile, based on the lognormal distribution?

ANSWER

Answered 2021-Jun-08 at 20:07

Given a log-normal distribution, we want to compute its quantiles. Furthermore, the parameters of the log-normal distribution are estimated from data.

The script below uses OpenTURNS to create the distribution using the LogNormal class. It takes as inputs arguments the mean and standard deviation of the underlying normal distribution. Then we can use the computeQuantile()method to compute the quantiles.

The typical reason for the fail is: wrong starting parameters. The formulae used here are somewhat those that would be used for a measurement statistic, while the data here has to be considered the according histogram. The use of n, hence, does not make sense. It is more like
