Defog
By modeling the imaging features of smoke, dust, fog, etc., defog technology effectively
restores details and color to obtain accurate and natural video. Defog technology helps
maintain clarity in images captured in poor weather conditions such as rain, smog, or
fog. I'm guessing this will be used for the Thermo camera.
ROI
In some surveillance scenarios, users pay special attention only to a certain region
instead of the entire image. The region that attracts special attention is known as the
region of interest, or ROI. The ROI encoding method was developed to provide different
compression levels between the ROI and background information in order to capture
clearer key information without increasing the overall bitrate. The application of ROI
encoding technology helps to conserve bandwidth and optimize the bitrate resource
allocation, thus ensuring the image quality of the region of interest.
