Utilizing the median method to extract initial background from video sequences, which serves as a fundamental preprocessing step in video processing for background extraction and real-time updating. This approach involves statistical analysis of pixel values across multiple frames to establish a robust baseline.
1. Image scale transformation through resolution reduction using local averaging and median filtering methods; 2. Image quality assessment using mean, standard deviation, information entropy, and average gradient metrics with implementation approaches
