Latest Patents

One of his latest patents is titled "Method and apparatus for dense motion field based coding." This invention involves an encoder that generates an estimate of apparent inter-image motion by utilizing a dense motion field in a sequence of video frames or other images. The estimate includes a motion vector for each pixel of the dense motion field and is generated as a solution to a constrained optimization problem based on a multiscale data model. This model characterizes the motion between pixels and designated neighbor pixels, ensuring efficient motion compensation in encoding images.

Another significant patent by Servetto is "High-capacity digital image watermarking based on waveform modulation of image components." In this invention, digital watermark information is inserted into an image by separating it into components, such as discrete cosine transform (DCT) blocks. The digital watermark information is associated with each component by modulating them with selected waveforms. This technique allows for the generation of distinct watermarks, enhancing the reliability of watermark detection even in the presence of noise.
