This paper presents unsupervised mask patterns generation for extracting action specific motion features. Cubic Higher-order Local Auto-Correlation (CHLAC) feature is robust to position changes of human actions in a video, and it is effective for action recognition. However, the mask patterns for extracting features are fixed. In other words, the mask patterns are independent of action classes. This...
This paper presents a scene classification method using criterion mining and adaptive integration. Since scene classification requires scene composition and shift-invariant similarity of fine parts, the latter two are represented by global and local Kernel Principal Component Analysis (KPCA), respectively. In addition, the reconstruction errors obtained with either KPCA are integrated adaptively with...
This paper proposes an adaptive integration method of reconstruction errors obtained from different point of view. There are some methods for integrating local and global processing. However, integration parameters are fixed for all test samples though effective parameters are different for every sample. Therefore, we select adaptively the parameters from only a test image. In static image recognition,...
