Latest Patents

Haibin Ling holds a patent for "Diffusion distance for histogram comparison." This patent introduces a novel measure to compare histogram-based descriptors through a diffusion distance. The method defines the difference between two histograms as a temperature field. It discusses the relationship between histogram similarity and the diffusion process, demonstrating how diffusion effectively manages deformation and quantization effects. The diffusion distance is derived as the sum of dissimilarities over scales, making it robust against deformation, lighting changes, and noise in histogram-based local descriptors. Furthermore, it boasts linear computational complexity, significantly improving upon previously proposed cross-bin distances that had quadratic complexity or higher. The proposed approach has been tested on shape recognition and interest point matching tasks using various multi-dimensional histogram-based descriptors, including shape context, SIFT, and spin images. In all experiments, the diffusion distance has shown excellent performance in both accuracy and efficiency compared to other state-of-the-art distance measures, matching the accuracy of the Earth Mover's Distance while offering greater efficiency.
