Detection of pulmonary nodules combined of extraction by multi-directions PCA and identification by 3D (three dimension) BP neural network is presented in the paper, which is different from most lung CAD algorithms, that it does not require any a priori information by human intervention but solely the information contained by the CT image itself, and it is capable to perform full automation which...
In this paper, a novel digital watermarking scheme is devised based on improved Back-Propagation neural network (BPN) for color image. The watermark is embedded into the discrete wavelet domain of the original image and extracted by training BPN, which can learn the characteristic of the image. For improving the performance of traditional BPN, we consider the adding of momentum coefficient to reduce...
