We describe three modifications to the structure tensor approach to low-level feature extraction. We first show that the structure tensor must be represented at a higher resolution than the original image. Second, we propose a non-linear filter for structure tensor computation that avoids undesirable blurring. Third, we introduce a method to simultaneously extract edge and junction information. Examples demonstrate significant improvements in the quality of the extracted features.
