Problems solved by technology

For a long time, low-resolution terahertz images have poor imaging clarity and contrast, unclear edge outlines, and coherent speckle noise interference, which has become one of the main factors hindering the application of terahertz images.
[0003] Combining image processing technology with terahertz imaging principles, terahertz images can be recognized, but using low-resolution images for semantic segmentation, although the recognition rate is high, many small and important details are lost compared to high-resolution images

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method for interpreting terahertz image information, a network and a storage medium. Background technique [0002] Terahertz technology can carry out non-contact automatic identification of hidden dangerous objects, and can solve the technical problems of safety detection in public environments. For a long time, the poor imaging clarity and contrast of low-resolution terahertz images, unclear edge contours, and coherent speckle noise interference have become one of the main factors hindering the application of terahertz images. [0003] Combining image processing technology with terahertz imaging principles, terahertz images can be recognized, but using low-resolution images for semantic segmentation, although the recognition rate is high, many small but important details are lost compared to high-resolution images . [0004] In order to obtain the information that the image i...
