Resource Overview
MATLAB implementation for computing horizontal and vertical projections of images, featuring pixel distribution analysis for feature extraction.
Detailed Documentation
This is a MATLAB program designed to compute horizontal and vertical projections of images. The program performs projection calculations along both horizontal and vertical axes by analyzing pixel intensity distributions across these directions. It implements projection feature extraction through column-wise sum operations for vertical projections (summing pixels along each column) and row-wise sum operations for horizontal projections (summing pixels along each row). Key functions utilized include imread() for image loading, sum() for projection calculations, and plot() for visualizing the projection profiles. This tool enables users to extract projection characteristics that reveal image patterns and structural information, supporting subsequent analysis of image features and composition through quantitative distribution metrics.
