Unequal error protection of PCA-coded face images for transmission over mobile channels

In this paper, a system for reliable communication of coded grey-level face images over noisy channels is proposed. Principal Component Analysis (PCA) is used for face image coding and an unequal error protection (UEP) joint source channel coding scheme is proposed for mobile communication applications. Coded images are protected with convolutional codes for transmission over mobile channels. Recognition rates obtained with UEP system approach the 95% recognition performance for images from the ORL face database.
