 amplitude  error and relaxation time error after the envelope fitting for
the signal filtered.So the adaptive notch filter can effectively remove the

Image tampering will destroy the light coherence of natural images. In order to ensure the security of image content, this paper presents a blind identification method based on the consistency of illuminant direction to identify the image authenticity. In accordance with the error function between the measured intensity and calculated intensity, and the regularization terms for different source models, this method estimates the illuminant direction for images of different source models. Analyzing if the illumination directions between different objects and background in one image are consistent to determine whether the image has been tampered with. Experimental results show that the correct detection rates for blind identification technology for digital images based on infinite light source model has reached up to 81.8%. In addition, experiments also show the effectiveness of blind identification base on local light source and composite light sources.

To improve the real-time performance of the current compression algorithms on hyperspectral image, a new lossless compression method based on prediction tree with error variances compensated for hyperspectral image is proposed. The method incorporates prediction tree and adaptive interband prediction techniques.The bidirectional interband prediction to current band is applied to hyperspectral image compression. The error created by prediction tree is compensated by linear adaptive predictor which de-correlates spectral statistic redundancy. In consideration of the complexity for the coefficients calculation, a correlation-driven adaptive estimator is designed with which parameters are uniquely determined by the previously coded pixels. After de-correlating intraband and interband redundancy, an efficient wavelet coding method, SPIHT (Set Partitioning in Hierarchical Trees), is used to encode residual image. The experiments show that the proposed method achieves both low overhead and high compression ratio in comparison with the popular lossless compression algorithm.
