This paper proposes a new robot needle insertion trajectory planning method based on learning expert's skill. Through reforcement learning, the system can imitate the expert's behavior in planning optimal needle insertion policy. After learning two experts' skill and experience, the needle insertion optimal policy shows that each one can catch the main(More)
For fractal image coding, flat range blocks are reconstructed only by their mean pixel values, and non-flat range blocks are reconstructed by the best matching domain blocks that are most similar to the range blocks selected from non-flat domain blocks. So, the threshold values of standard deviation for flat/non-flat range blocks and for flat/non-flat(More)
