In this chapter we … Human Action Recognition (HAR) attempts to recognize the human action from images and videos. The major challenge in HAR is the design of an action descriptor that makes the HAR system robust for different environments. A novel action descriptor is proposed in this study, based on two independent spatial and spectral filters. The …
WebOct 2, 2024 · Linear discriminant analysis (LDA) is not just a dimension reduction tool, but also a robust classification method. With or without data normality assumption, we can arrive at the same LDA features, which explains its robustness. Introduction LDA is used as a tool for classification, dimension reduction, and data visualization. WebJun 22, 2015 · This paper develops the theory of robust regression (RR) and presents an effective convex approach that uses recent advances on rank minimization. The framework applies to a variety of problems in computer vision including robust linear discriminant analysis, regression with missing data, and multi-label classification.
