In the multi-watermarking algorithm, will be presented and used a conventional cryptography and digital watermarking production method--- superposition method and quantify the modulation method, combine the new method, the watermark embedding different watermark, associated with the watermark generating different keys, making extraction of the watermark when tested with a different image key and the corresponding extracted watermark. By the key to a third party registration, can be obtained ownership of the original image.)

A-Bayesian-Adaptive-Basis-Algorithm-for-Single-Pa
Traditional single particle reconstruction methods use either the Fourier or the delta function basis to represent the particle density map. We propose a more flexible algorithm that adaptively chooses the basis based on the data. Because the basis adapts to the data, the reconstruction resolution and signal-to-noise ratio (SNR) is improved compared to a reconstruction with a fixed basis. Moreover, the algorithm automatically masks the particle, thereby separating it from the background. This eliminates the need for ad-hoc filtering or masking in the refinement loop. The algorithm is formulated in a Bayesian maximum-a-posteriori framework and uses an efficient optimization algorithm for the maximization. Evaluations using simulated and actual cryogenic electron microscopy data show resolution and SNR improvements as well as the effective masking of particle from background
