With the development of optical character recognition research, many techniques for printed character recognition have been developed. But the character recognition study for the New Tai Lue has lagged behind. As a result, the digital processes of New Tai Lue have been in troubles. To solve this problem, this paper proposed a printed New Tai Lue character recognition method based on the Back Propagation...
This study addresses the issue of region representation in region-based image retrieval (RBIR). In order to reduce the user's burden of selecting the region of interest, a statistical index called visual region importance (RI) is constructed to describe the region. By learning from user's current and historical feedback information, visual RI can be automatically updated and semantic RI can be obtained...
In this paper, we develop a rotation-invariant (RI) texture descriptor, termed generalized local binary pattern (GLBP). The proposed GLBP captures more detailed information by integrating local features in inter-directions and relative distribution among intra-directions. GLBP is characterized by extracting LBP-sign and LBP-magnitude to describe local structures jointly, and performing Fourier transform...
This paper proposes an adaptive image retrieval method via spatial-frequency mixed features (SFMF). The SFMF can describe spatial and frequency information of image simultaneously. More specifically, spatial feature is local binary pattern (LBP) histogram extracted from image. Frequency features are described as the generalized Gaussian density (GGD) of Contourlet transform detail coefficients and...
This paper presents a method for extracting texture and color hybrid features and constructing an adaptive weight operator, which can be used for content-based image retrieval (CBIR). This method extracts texture feature effectively based on Brushlet transform, quantifies in the HSV space, and extracts color feature by color histogram. K-mean clustering is introduced to count overall characteristics...
