BBox

I managed to find in someone who made a class for rounded buttons in tkinter that works great. However the issue I have is there is always a white border. I've tried reading through all of the code and changing all of the colour values but to no avail.

Here is an excerpt of the code working, I've tried to format it as nicely as I could:

Background

I have a video with people walking around different homes. I implemented 3 different timers (for 3 different people) that begin timing when the people are inside the bboxes of the homes and pause when they are outside of the bboxes of the homes. For reference, I have included a visual of what the first frame of the video looks like.

Problem

The check implemented in the code below works fine - it returns True when a person's bbox is inside of a home bbox and returns False otherwise. I'm having difficulties when it comes to pausing the time as a person is walking around outside of the home bbox (i.e. when a person's bbox is not inside of a home bbox). As you can see in the code below, I used time.sleep(1) to pause the timer for a second each time a False is returned, however, this doesn't seem to work. It just keeps the timer running in the background. For example, if person 1's timer is at 15 seconds before a False is returned, its timer should pause. Then, when a True is returned, its timer should resume its time from 15 seconds and increment. However, in my case right now, it keeps running the timer in the background so when a True is returned after a False, the timer suddenly shows up as 24 seconds instead of resuming from where it left off before the time.sleep(). How do I go about solving this issue?

I'm trying to scale a QPolygonF that is on a QGraphicsScene's QGraphicsView on its origin.

However, even after translating the polygon (poly_2) to its origin (using QPolygon.translate() and the center coordinates of the polygon received via boundingRect (x+width)/2 and (y+height)/2), the new polygon is still placed on the wrong location.

The blue polygon should be scaled according to the origin of poly_2 (please see the image below, black is the original polygon, blue polygon is the result of the code below, and the orange polygon is representing the intended outcome)

I thought that the issue might be that coordinates are from global and should be local, yet this does solve the issue unfortunately.

Here's the code:

The objective is to create subplot for the jointplot annotate with correlation. However, when plt.show(), the figure were displayed separately.

May I know how to solve this issue?

I've seen ways of using the time.sleep() function, however that stops the rest of the code from running.

I'm making a hand recognition script and want the video output to be hindered by a certain value being printed every second.

This is my code:

I am trying to write an object detection + text-to-speech code to detect objects and produce a voice output on the raspberry pi 4. However, as of right now, I am trying to write a simple python script that incorporates both elements into a single .py file and preferably as a function. I will then run this script on the raspberry pi. I want to give credit to Murtaza's Workshop "Object Detection OpenCV Python | Easy and Fast (2020)" and https://pypi.org/project/pyttsx3/ for the Text to speech documentation for pyttsx3. I have attached the code below. I have tried running the program and I always keep getting errors with the Text to speech code (commented lines 33-36 for reference). I believe it is some looping error but I just can't seem to get the program to run continuously. For instance, if I run the code without the TTS part, it works fine. Otherwise, it runs for perhaps 3-5 seconds and suddenly stops. I am a beginner but highly passionate in computer vision, and any help is appreciated!

I would like to extract the unit of measurement (decimal degrees, metres, feet, etc.) from a spatial object in R. For example, if I have an SF data frame that uses the WGS84 co-ordinate reference system (EPSG:4326), I would like to be able to determine that the co-ordinates are specified in decimal degrees. Similarly, I'd like to be able to determine that UTM co-ordinates (e.g. EPSG:32615) are specified in metres.

I have tried using the st_crs() function from the sf package, which returns the co-ordinate reference system in well-known text format. However, I'm struggling to be certain that a regex that extracts the unit of measurement from that well-known text will operate reliably for a wide range of co-ordinate systems.

Is there an existing function that returns the measurement unit for a spatial object?

For example, the following code produces an SF data frame that uses the WGS84 co-ordinate system:

I have made the following query using the osmdata package:

Given the following code:
