QUESTION

What is the Sobel operator?

Asked 2021-Jun-15 at 18:13

I tried 5 different implementations of the Sobel operator in Python, one of which I implemented myself, and the results are radically different.

My questions is similar to this one, but there are still differences I don't understand with the other implementations.

Is there any agreed on definition of the Sobel operator, and is it always synonymous to "image gradient"?

Even the definition of the Sobel kernel is different from source to source, according to Wikipedia it is [[1, 0, -1],[2, 0, -2],[1, 0, -1]], but according to other sources it is [[-1, 0, 1],[-2, 0, 2],[-1, 0, 1]].

Here is my code where I tried the different techniques:

according to wikipedia it's [[1, 0, -1],[2, 0, -2],[1, 0, 1]] but according to other sources it's [[-1, 0, 1],[-2, 0, 2],[-1, 0, 1]]

Both are used for detecting vertical edges. Difference here is how these kernels mark "left" and "right" edges.

For simplicity sake lets consider 1D example, and let array be

[0, 0, 255, 255, 255]

then if we calculate using padding then

kernel [2, 0, -2] gives [0, -510, -510, 0, 0]
kernel [-2, 0, 2] gives [0, 510, 510, 0, 0]

As you can see abrupt increase in value was marked with negative values by first kernel and positive values by second. Note that is is relevant only if you need to discriminate left vs right edges, when you want just to find vertical edges, you might use any of these 2 aboves and then get absolute value.

Seaborn FacetGrid multiple page pdf plotting

Asked 2021-Jun-14 at 17:37

I'm trying to create a multi-page pdf using FacetGrid from this (https://seaborn.pydata.org/examples/many_facets.html). There are 20 grids images and I want to save the first 10 grids in the first page of pdf and the second 10 grids to the second page of pdf file. I got the idea of create mutipage pdf file from this (Export huge seaborn chart into pdf with multiple pages). This example works on sns.catplot() but in my case (sns.FacetGrid) the output pdf file has two pages and each page has all of the 20 grids instead of dividing 10 grids in each page.

Answered 2021-Jun-14 at 17:16

You are missing the col_order=cols argument to the grid = sns.FacetGrid(...) call.

Being an absolute beginner, I'm facing some issues in my simple math quiz in python.

First Issue: In my programme, the answer is stuck with option d only, i want to swap the correct option between the choice a-d every time.

Second Issue: i declare a variable "score" and i try to increment it's value on each correct answer, but it's is not updating.

Third Issue : I want to clear Previous question on selecting correct option and ask a new question.

My code is :

ANSWER

Answered 2021-Jun-14 at 15:58

This code first stores the answer in a random option, and then the answer variable is given the value of the option, i.e a,b,c or d. I added the score variable as a parameter to the function and every time a correct answer is given the value of the parameter will be set equal to the score

A simple approach would be:

Generate a random first number (n1)
Generate a random multiplier (m)
Use the product of the first number and the multiplier as the second number (n2 = n1 * m)

The purpose of this code is to:

create a dummy data set.
Then turn it into a data frame
Calculate the peaks and make it a column in the data frame
Calculate the troughs and make it a column in the data frame
Filling the “nan” values with “hold”
Replace all the float values with the word “buy”

Here is an adaption of seaborn's ridgeplot example for the given structure. Here multiple='stack' is selected in sns.kdeplot (the default is multiple='layer' plotting them both starting from y=0). Note that common_norm defaults to True, which scales down both curves in proportion to the number of samples.

As seaborn works with data in "long form", pd.melt() transforms the given dataframe. The long form looks like:

QUESTION

Why random.randint() is much slower than random.getrandbits()

Asked 2021-Jun-13 at 11:52

A made a test which compares random.randint() and random.getrandbits() in Python. The result shows that getrandbits is way faster than randint.

...

ANSWER

Answered 2021-Jun-13 at 11:31

randint uses randrange which uses _randbelow which is _randbelow_with_get_randbits (if it is present) which uses getrandbits. However, randrange includes overhead on top of the underlying call to getrandbits because it must check for the start and step arguments. Even though there are fast paths for these checks, they are still there. There are definitely other things contributing to the 6.5 slowdown when using randint, but this answer atleast shows you that randint will always be slower than getrandbits.
