Image Segmentation in OpenCV Python with Watershed Algorithm
Image segmentation divides an image into distinct regions or objects. The Watershed algorithm is one of the most effective techniques for this task, treating grayscale images like topographical maps where pixel intensities represent elevations. Understanding the Watershed Algorithm The Watershed algorithm works by imagining water flowing from local minima (dark regions) until it meets boundaries between different regions. These boundaries become the segmentation lines, effectively separating objects in the image. Complete Implementation Here's a complete implementation of image segmentation using the Watershed algorithm − import cv2 import numpy as np import matplotlib.pyplot as plt ...
Read MoreHow to use if, else & elif in Python Lambda Functions
Python lambda functions are anonymous, single-line functions that provide a concise way to define small operations. When combined with conditional statements like if, else, and elif, they become powerful tools for inline decision-making logic. In this tutorial, we will explore how to incorporate conditional statements within lambda functions, demonstrating their syntax and practical applications through working examples. Basic Syntax A lambda function with conditional statements follows this general structure ? lambda arguments: expression_if_true if condition else expression_if_false The key components are ? lambda ? keyword to define the anonymous function arguments ...
