| Abstract: | It was introduced the function of quantization tables in the JPEG image based on the principle of the JPEG image compression algorithm and standard,designed a software to extract quantization tables from the JPEG images,put emphasis on analyzing the relationship between the extracted quantization tables and the image quality.The result of the experiments showed that the quantization table was an important factor affecting the image quality. |
