研究目的
To develop a face recognition method based on video broadcast under illumination variation, facial expressions, different pose, orientation, occlusion, nationality variation and motion.
研究成果
The proposed method combining LBP and HOG for feature extraction and RF for classification achieved an average recognition accuracy of 97.6%. The method proved efficient in recognizing faces in uncontrolled environments based on video broadcast.
研究不足
The study focuses on face recognition in uncontrolled environments based on video broadcast, which may not cover all possible real-world scenarios. The performance might vary with different datasets or under more extreme conditions.
1:Experimental Design and Method Selection:
The study proposed a combination of Histograms of Oriented Gradients (HOG) and Local Binary Pattern (LBP) descriptors for feature extraction and Random Forest (RF) for classification.
2:Sample Selection and Data Sources:
The Mediu staff database (Mediu-S-DB) was used, containing 22 broadcast videos for ten males from different races.
3:List of Experimental Equipment and Materials:
MATLAB 2016b Toolboxes for Computer Vision and Image Processing was used for coding the desired system.
4:Experimental Procedures and Operational Workflow:
Face detection was performed using the Viola-Jones algorithm, followed by feature extraction using LBP and HOG, and classification using RF.
5:Data Analysis Methods:
The efficiency of the RF classifier was compared with SVM classifiers using different feature extraction methods.
