In diagnostics stage, the sonogram of person with unknown diagnostics is taken and the most probable diagnosis is inferred. The paper uses Bayesian inference with Gaussian(More)

Functional deficiency of mannan-binding lectin (MBL) has been associated with adverse pregnancy outcome. Adverse events during pregnancy have also been described in women with autoimmune thyroid diseases (AITD), and thyroid hormones have been shown to influence serum levels of MBL.

The problem of automatic classification of ultrasound images is addressed. For texture analysis of ultrasound images quantifiable indexes , called features, are used. Classification was performed using Gaus-sian mixture model based on Bayes classifier. The common problem of texture analysis is a feature selection for classification tasks. In this work we(More)
