Title: Joan Bruna: Innovator in Video Processing Technologies
Introduction
Joan Bruna is a prominent inventor based in Paris, France. She has made significant contributions to the field of video processing, holding 2 patents that showcase her innovative approach to enhancing video quality and scaling techniques.
Latest Patents
Her latest patents include a "Method and apparatus for spatio-temporal subband video enhancement with small time delay." This invention focuses on video processing by computing transform coefficients using a spatio-temporal transform. It involves a spatial subband transform and a causal time wavelet transform that performs filtering with multiscale causal wavelets. The method modifies the transform coefficients with nonlinear processing and computes a processed video stream using a spatio-temporal reconstruction transform. This reconstruction comprises an inverse subband transform and a short delay inverse time wavelet transform, which is implemented with wavelet filters modified with window functions to control the processing delay.
Another notable patent is the "Method and apparatus for robust super-resolution video scaling." This invention applies to techniques for converting video sequence formats and deinterlacing. It includes a parameterized interpolation that computes interpolations at each new point of the output. The method also features an insensitive interval estimation that computes an interval where the probability distribution of the output image value is estimated to have its maximum. Additionally, it derives a negative log likelihood measurement from an interval-insensitive probability distribution, followed by spatial regularization and minimum loss selection for output image values.
