Grayscale Expansion and Grayscale Image Pseudocolorization

Grayscale expansion and grayscale image pseudocolorization: Pixels with grayscale values between 0-20 are displayed in blue, 20-40 in green, and 40-255 in red. This technique enhances visual distinction through color mapping algorithms.

Line Detection in Images with Enhanced Visualization

This program implements image processing techniques to detect lines in images, marking detected lines in green with '+' symbols indicating endpoints, while highlighting the longest line using a distinct color for better visual differentiation.
