In this paper, HSV based text on histogram (HSV-TH) is proposed for content based image retrieval (CBIR). The HSV-MT is proposed in contrast to the RGB based text on histogram (RGB-TH). The proposed HSV-TH method is based on Julesz's textons theory, and it works directly on nature images as shape descriptor and a color texture descriptor. HSV-TH integrates the advantages of co-occurrence matrix and...
Representation operator is one of the key issues of the content-based retrieval. In this paper, we propose an adaptive alpha-trimmed average operator based on Gaussian distribution hypothesis test for image representation. The adaptive alpha-trimmed average operator extracts the representation by trimming outliers and then estimating the central value of the rest. Since the more samples are used,...
