Aruco Marker Detection with OpenCV

OpenCV (Open Source Computer Vision Library) is a powerful open-source tool for computer vision and image processing tasks. Aruco markers are a type of augmented reality marker used for detecting and tracking objects in computer vision applications. We’ll explore how to use OpenCV to detect and work with Aruco markers in your projects.

How to use numpy logspace

I will explain how to use numpy logspace, a handy function for creating logarithmically spaced arrays. Such arrays are particularly useful in various scientific and engineering applications where data or phenomena span several orders of magnitude. For example, in frequency analysis, signal processing, or when dealing with exponential scales, logarithmic spacing is often more appropriate Continue reading

How to use random seed in Numpy

I’ll explain how to use the random seed in NumPy, a widely used Python library for scientific computing. Setting a random seed allows you to control the randomness in NumPy’s random number generators, which are essential for tasks like generating random data, shuffling arrays, sampling from distributions, and more.

How to resolve TypeError: Cannot perform reduce with flexible type

I will explain how to resolve the error TypeError: Cannot perform reduce with flexible type that may occur when using NumPy functions on arrays with different data types. NumPy is a popular Python library for scientific computing that provides fast and efficient operations on multidimensional arrays. One of the features of NumPy is that it Continue reading
