Research on infrared image compression based on region of interest automatic detected

Image compression based on region of interest has been one of hot issues in the field of image compression and coding. However, there is not a fixed model for region of interest automatic detected. In order to solve the transmission question for the infrared images through the low bandwidth data link, the method of ROI automatic detected in infrared images, based on a fast recurring algorithm based on two-dimensional entropy threshold, was studied in this paper while a compressed scheme based on ROI automatic detected was proposed. An experimental study was also conducted after the compressed scheme realized on the frame of JPEG2000. It was proved that the method of ROI automatic detected not only can meet real-time requirements, but also was reliable, effective and significant in applications.
