However, to achieve a high coding gain, an advanced way for context assignment is required. In this paper, the local frequency table technique is adopted to improve the coding efficiency of context-based adaptive arithmetic coding in text compression. With it, the probability distribution of the characters to be encoded can be estimated more accurately and a higher compression ratio can be achieved. Experimental results show that the proposed coding algorithm with a local frequency table outperforms other methods and achieves better compression performance for text compression.[SDGs]SDG4conference paper10.1109/ICCE-Taiwan55306.2022.98692712-s2.0-85138739130https://api.elsevier.com/content/abstract/scopus_id/85138739130
