Abstract
In a method for video encoding, one or more parameters are determined for a region of interest (ROI) within a digital image. The parameters relate to a size, location, and shape of the ROI. Multi-segment downsampling is performed on the input image to generate a downsampled image having fewer pixels than the digital image. The downsampling uses a different sample density for the ROI than for a portion of the digital image outside the ROI. The downsampled image is encoded to generate encoded image data and the encoded image data is combined with the one or more parameters to generate combined data, which may then be transmitted or stored. A method for video decoding comprising decoding the encoded video and performing multi-segment upsampling on the decoded video is also disclosed.
