To deal with the poor stability of tracking infrared target by using the gray-level features in traditional methods, a novel method is provided for tracking target in infrared based on color image fusion. Firstly, This method uses the color transfer technology to achieve the color fusion image for the infrared target. On the basis of the color image, the color histogram is established by kernel function...
An age classification algorithm based on multi-feature weighted decision fusion is proposed. On the basis of calibration for the facial positive posture, the facial texture features are extracted by three methods. Firstly, the uniform local binary pattern (ULBP) histogram is extracted through the Gabor wavelet transform which has the multi-scale and multi-directional characteristics. Secondly, an...
The traditional steganography methods with Pixel Value Differencing (PVD) usually only deal with the PVD in the horizontal direction but ignore the vertical one. In this paper, the cover image is divided into 2×2 nonoverlapping blocks, then the modulus function method is used in horizontal direction and the simple PVD method is used in vertical direction for steganography. In addition, the falling-off-boundary...
In this paper, we present a robust system to accurately detect and localize texts in natural scene images. For text detection, a region-based method utilizing multiple features and cascade AdaBoost classifier is adopted. For text localization, a window grouping method integrating text line competition analysis is used to generate text lines. Then within each text line, local binarization is used to...
