Motion object detection serves as the fundamental basis for subsequent tracking techniques in video processing. The quality of detection results directly determines whether moving targets can be successfully tracked and the accuracy of tracking performance. This process involves segmenting and extracting foreground, motion, and targets from sequential images acquired by machine vision systems. This paper describes primary methods for motion detection in computer vision, introduces principles and characteristics of typical background subtraction algorithms, details the four-step workflow of background differencing (preprocessing, background modeling, target detection, and post-processing), and implements background subtraction algorithms in MATLAB for video-based motion detection with additional image processing of detection results.

High-quality MATLAB source code for motion object detection with advanced algorithmic features
MATLAB background subtraction algorithm for motion detection, involving background model establishment, frame-by-frame subtraction between current and background models, threshold comparison for target identification. Larger differences indicate motion targets while smaller differences suggest no movement. Optimal threshold can be empirically adjusted through parameter tuning for improved detection accuracy. Code implementation typically uses imabsdiff() function for difference calculation and imbinarize() for thresholding operations.

This implementation utilizes the frame difference method for motion target detection to effectively detect and track pedestrians in video sequences, demonstrating excellent performance that can serve as a valuable reference for learning and implementation.
For moving target detection and recognition in infrared image sequences, we propose an original approach addressing infrared target detection in complex dynamic scenes. The method utilizes cross-entropy-based transition zone extraction to enhance detection accuracy and robustness, implemented through entropy thresholding and morphological operations for precise target segmentation.
