Arithmetic Operations on Images - OpenCV

Bitwise Operations. This includes the bitwise AND, OR, NOT, and XOR operations. They will be highly useful while extracting any part of the image (as we will see in coming chapters), defining and working with non-rectangular ROI's, and etc. Below we will see an example of how to change a particular region of an image.

Python Operators: The Complete Guide – TheLinuxCode

Bitwise operators for bit-level operations; Assignment operators for assigning values; ... In Python, logical operators work with non-Boolean values too: # For ‘and‘: Returns the first falsy value, or the last value if all are truthy print(0 and 42) # 0 (first falsy value) print(42 and "hello") # "hello" (last value, all are truthy) # For ...

Check If All 1's Are at Least Length K Places Away

This Python solution checks if all '1's in an array of binary numbers are separated by at least a given minimum distance (gap). Here's how it functions: Start by converting the array of binary numbers into a single integer. This transformation involves iterating through the array and using bitwise operations to shift and set bits.

Extract horizontal and vertical lines by using morphological operations

Two of the most basic morphological operations are dilation and erosion. Dilation adds pixels to the boundaries of the object in an image, while erosion does exactly the opposite. The amount of pixels added or removed, respectively depends on the size and shape of the structuring element used to process the image. In general the rules followed ...
