To overcome the disadvantage of describing contents of an image only with global features, a new color cluster image retrieval algorithm based on object regions is proposed. In this paper, firstly, object regions are extracted from an image, and then a new color cluster algorithm is presented. The algorithm is developed based on HVS color space, histogram intersection and combination of two similarity...
Based on local audio feature and support vector regression (SVR), an adaptive blind audio watermarking algorithm in wavelet domain is proposed in this paper. The audio signal is partitioned into audio frames, and the watermark is embedded in wavelet domain. For each audio frame, the energy and the maximal peaks of its all sub-bands are extracted as the local features, and SVR is used to model the...
Due to colony image quality variation very much, an ordinary colony delineation algorithm is difficult to segment all kinds of colony images, therefore, image classification is necessary before image segmentation. The developed special colony image classification method in this study is to use definition of judgment set, determination of fuzzy judgment matrix, and defining weight set based on colony...
