Latest Patents

One of his latest patents is titled "Method and device for processing of an image by regularization of total variation." This invention tackles the limitations of traditional Total Variation, which primarily enforces horizontal and vertical intensity continuity, often failing to reconstruct oblique edges effectively. In this embodiment, Directional Total Variation is defined to support multiple gradient directions. The process involves pre-processing the image to determine the direction of edges and textures. Directional TV is then calculated based on gradients along the determined direction and its orthogonal counterpart. By applying adaptive weights to different directions in the regularization, Directional TV can preserve edges regardless of their orientation, leading to improved quality in image denoising, compression, or super-resolution.

Another significant patent by Wen Fei Jiang is "Image filtering based on structural information." This method and apparatus utilize structural information during the calculation of filtering coefficients. The structural information is derived from regions defined through an edge map of the image. In one embodiment, the region correlation between the target pixel and a contributing pixel is selected as a structural filtering coefficient. This correlation indicates the likelihood of two pixels being in the same region and is calculated by evaluating the strongest edge cut by a path between the target pixel and a contributing pixel. The structural filtering coefficient is then combined with spatial and intensity information to create a spatial-intensity-region (SIR) filter. This innovative filter is applicable in various areas, including denoising, tone mapping, and exposure fusion.
