چکیده
Face recognition has great demands and become one of the most important research area of pattern recognition but there are several issues involved in it. Unsupervised statistical methods i.e. PCA, LDA, ICA are the most popular algorithms in face recognition that finds the set of basis images and represents faces as linear combination of those images. This paper presents a novel layered face recognition method based on CSLDA and LDA. The basic aim is to decrease FAR by reducing the face dataset to very small size through layered linear discriminant analysis. Although the computational complexity at the time of recognition is much higher than conventional PCA and LDA because weights are computed for small subspace at time of recognition but it provide a good results especially for large dataset. CSLDA of LDA is insensitive to large dataset and also small sample size and it provided 84% accuracy on Banca face database. The proposed approach is also applicable on other applications and recognition methods i.e. PCA, KDA, DLDA etc. Streszczenie. Rozpoznawanie twarzy jest jedną z bardziej ważnych metod graficznego rozpoznawania wzorów. Najbardziej popularnymi metodami są tu PCA, LDA, ICA gdzie twarz jest reprezentowana jako liniowa kombinacja bazowych komponentów. Artykuł prezentuje inną metodę bazującą na CSLDA i LDA. Głównym celem jest zmniejszenie FAR przez zredukowanie bazy danych do bardzo małych rozmiarów przez warstwową liniową dyskryminację. Złożoność komputerowa metody jest nieco większa ale otrzymane rezultaty, głównie zmniejszenie błędu są zachęcające. (Rozpoznawanie twarzy przez fuzję metod CSLDA i LDA).

متن کاملFusion of LDA and PCA for Face Recognition
Although many approaches for face recognition have been proposed in the last years, none of them can overcome the main problem of this kind of biometrics: the huge variability of many environmental parameters (lighting, pose, scale). Hence, face recognition systems can achieve good results at the expense of robustness. In this work we describe a methodology for improving the robustness of a fac...
متن کاملFusion of Face Recognition Algorithms for Video-based Surveillance Systems
It is widely acknowledged that face recognition could play an important role in advanced video-based surveillance systems, mainly because it is non-intrusive and does not require people cooperation. Unfortunately, face recognition algorithms showed to suffer a lot from the high variability of environmental conditions (e.g., variations of lighting, face pose and scale). This currently limits the...
متن کاملLearning Polylingual Topic Models from Code-Switched Social Media Documents
Code-switched documents are common in social media, providing evidence for polylingual topic models to infer aligned topics across languages. We present Code-Switched LDA (csLDA), which infers language specific topic distributions based on code-switched documents to facilitate multi-lingual corpus analysis. We experiment on two code-switching corpora (English-Spanish Twitter data and English-Ch...
