Abstract
Provided are an adaptive image compression system and method. The adaptive image compression method includes a step of determining, at an adaptive image compression system, characteristics of an image that is to be compressed, a step of determining, at the adaptive image compression system, a quantization scale factor based on the characteristics of the image that is to be compressed, a step of generating an adaptive quantization table corresponding to the image that is to be compressed based on the determined quantization scale factor, and a step of encoding the image that is to be compressed using the generated adaptive quantization table.
