In this paper, we shall propose an alternative method to estimate the Euclidean distance between an image block and a codeword. Our method incorporates the reduced code look-up table (RCLUT) method with an RCLUT-like method we propose to allow alternative selection in the encoding phase in Vector Quantization (VQ). This method can speed up the computation for distance estimation. It provides better image quality than the RCLUT method does at the cost of some extra storage. According to the experimental results, we see that our method provides better image quality than the RCLUT method.
