Abstract

The present invention relates to a method for automatically detecting the region of interest (ROI) in the image. In the method for automatically detecting ROI in the image, by conferring the coefficient after conversion of the image in the compression process, the incorporation of the variations of position and frequency of the coefficient block, and the compression bit rate requirement, detection is automatically conducted to generate the ROI of an image-related content variation. The bit flow of the related application is encoded for the different compressing process selections of the specified region based on each compressed standard so as to raise the vision quality of the ROI image after the decompression. In addition, the coefficient data after analysis and conversion is proposed, and is sorted into a small unit block so as to locate the center point of the interested small unit block assembly and use image processing skill to generate a continuous and closed mask for the ROI. The present invention is capable of having more adaptable characteristic for the requirement of the image content and the compressed bit rate. In addition, because the generation mechanism of the ROI mask is embedded in the compression procedure, the present invention also has the characteristic of low calculation cost.
