Abstract

In this paper, an ultrasonic televiewer image encoding method based on block prediction is proposed. The original image is divided into blocks of 8-by-8 pixels. The current block to be encoded is predicted from previously encoded and decoded blocks. The prediction mode that minimizes the differences between the original and predicted is chosen from 9 modes. The prediction difference block is transformed with Discrete Cosine Transform (DCT), and the DCT coefficients are quantized and encoded with lossless algorithm. The prediction modes selected are also encoded. Experimental results show that the performance of the proposed method is much better than JPEG.
