发明名称 Adaptive image compression system and method
摘要 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.

主权项 1. An adaptive image compression method comprising: determining, at an adaptive image compression system, characteristics of an image that is to be compressed; determining, at the adaptive image compression system, a quantization scale factor based on the characteristics of the image that is to be compressed; generating an adaptive quantization table corresponding to the image that is to be compressed based on the determined quantization scale factor; and encoding the image that is to be compressed using the generated adaptive quantization table, wherein determining, at the adaptive image compression system, the characteristics of the image that is to be compressed comprises: dividing a gray image corresponding to the image that is to be compressed into a plurality of blocks; calculating a characteristic value of each of the divided blocks; and determining the characteristics of the image that is to be compressed based on the calculated characteristic value of each of the divided blocks.
