Resource Overview

A MATLAB function for computing regional energy in images, featuring straightforward implementation with separate calculations for diagonal, horizontal, and vertical directional energies.

Detailed Documentation

This MATLAB function calculates regional energy in different directions within images. The implementation uses efficient matrix operations to compute energy across diagonal, horizontal, and vertical orientations separately. The function employs convolution with directional filters (such as Prewitt or Sobel kernels) to extract gradient information, then performs energy accumulation within specified regions. For computer vision and image processing professionals, this function provides valuable insights into image analysis by generating distinct energy maps based on image characteristics. The output includes customizable parameters for region size and energy normalization, helping users better understand structural patterns and feature distributions in images through quantitative energy measurements.
