Latest Patents

Cavigelli holds a patent titled "Edge-aware spatio-temporal filtering and optical flow estimation in real time." This patent presents a method for edge-aware spatio-temporal filtering. In one embodiment, a filtering application receives a guiding video sequence and additional video sequences from other channels. The application estimates a sparse optical flow from the guiding video sequence using a novel binary feature descriptor integrated into the Coarse-to-fine PatchMatch method. This method computes a quasi-dense nearest neighbor field. The filtering application then performs spatial edge-aware filtering of the sparse optical flow to obtain a dense flow, along with the additional channels. This is achieved through an efficient evaluation of the permeability filter with only two scan-line passes per iteration. Furthermore, the application performs temporal filtering of the optical flow using an infinite impulse response filter that requires only one filter state updated based on new guiding video sequence frames. The resulting optical flow can then be utilized in temporal edge-aware filtering of the additional channels using the nonlinear infinite impulse response filter.
