============================================

Analyzes a grayscale image, plots its column and row intensity histograms, and identifies continuous sections within a specific range of columns where the pixel values exceed a specific value, providing the start and end pixel indices for each identified section, and the number of sections which is wider than a specific pixel number. Code:

Output:
