Research on the Aesthetic Features and Technology of Computer Graphics

Computer graphics is a new science produced with the popularization of computers. The processing technology and images in computer has attracted much attention. How to make reasonable use them become an important subject field modern scientific applications. For this research background, paper proposes image recognition algorithm based on wavelet DFB-PCA. After decomposing transform, DFB-PCA performed low frequency subband. experimental results show that method beneficial reduce influence factors such as illumination, posture expression, dimensionality noise recognition, better robustness. Compared directly using PCA original image, calculation speed efficiency can be improved.
