In this paper, the problem of simultaneous wavelet estimation and deconvolution is investigated with a Bayesian approach under the assumption that the reflectivity obeys a Bernoulli-Gaussian distribution. Unknown quantities, including the seismic wavelet, the reflection sequence, and the statistical parameters of reflection sequence and noise are all(More)
Object shape recognition is important for cell microscopic image. Previous works have used circularity to describe the shape feature for different objects. In this paper, we propose an alternative shape feature, roundness curve, to represent the shape of object and classify cell microscopic image. The roundness curve is extracted based on the central(More)
