MATLAB M-File for Video Frame Extraction and Grayscale Conversion in Image Processing

This MATLAB M-file demonstrates the initial step in video image processing by extracting frames from video files and converting them to grayscale images. In this implementation, we first load the video file using VideoReader function and select a specific frame for extraction. The color image is then converted to grayscale utilizing MATLAB's rgb2gray function, which applies the luminance-preserving conversion formula: 0.2989 * R + 0.5870 * G + 0.1140 * B. This grayscale conversion simplifies image analysis by reducing computational complexity and focusing on intensity information for subsequent processing steps. Image processing represents a fascinating and crucial field in computer vision, and while this M-file covers only the foundational step, numerous advanced techniques including edge detection, filtering, and morphological operations await further exploration. This implementation serves as an excellent starting point for beginners entering image processing and aims to spark interest in this dynamic research domain!
