How to scatter plot two concentric circles with Numpy and Matplotlib Question: I’m trying to recreate the following plot with Numpy and Matplotlib as part of a question, but I’m struggling to get the "random aspect" of the plot: I’ve already managed to create the two circles and plot them with this code: import numpy …
remove polygons with an intersection higher than a threshold Question: The goal is to remove polygons with an intersection higher than a threshold, let’s say 80% of the area from the smaller intersected polygon. In the following picture we see in first image how the small red circle in coordinate (2.06, 41.41) is overlapping with …
Is it possible to calculate real-time distance of an object in a image w/o reference objects? Question: I have a picture of human eye taken roughly 10cm away using a mobile phone(no specifications regarding the camera). After some detection and contouring, I got 113px as the Euclidean distance between the center of the detected iris …
how to draw a line knowing the starting coordinate, line length x angle and y, angle Question: I am trying to draw a line knowing the starting coordinate, line length x angle and y, angle. I am trying to visualize the eye gaze direction of a human in a video. For an example, I want …
tkinter rounded button has white border Question: 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 …

Python function to find a point of an equilateral triangle Question: I am trying to write a function equilateral(x, y): that takes two np.ndarrays of shape (N,) , where x and y are natural numbers and returns a point z an np.ndarray of shape (N,) such that (x, y, z) are are the vertices of …
Intersection of two line segments in Python Question: Different articles have discussed about the intersection of two line segments in Python such as How do I compute the intersection point of two lines?, Numpy and line intersections, How can I check if two segments intersect? But, no one made it perfect since, they did not …
Using vector cross product to hide 3D faces Question: The code creates 3D coordinates for the cube and then displays them on the 2D screen but you can still see the back faces of the cube. What is the best method for hiding these faces? points = [(-1,-1,-1),(-1,-1,1),(-1,1,1),(-1,1,-1), (1,-1,-1),(1,-1,1),(1,1,1),(1,1,-1), ]#coords for points faces = [(3,0,4,7),(1,5,6,2),(2,1,0,3),(5,4,7,6),(3,2,6,7),(0,1,5,4)] …
Position + Euler Angles to Transformation Matrix Question: I have a position and three Euler angles from a Unity scene: # position cam_pos = [-0.1219461, -0.04402884, -1.995793] # rotation (in degrees) cam_rot = [-1.261, 176.506, 0.038] In Unity the coordinate system is LHS and the Euler angle convention is Z,X,Y. I’d like to know how …
