Abstract :
A binary hypothesis testing is a common tool in the task of object detection. Experiments with real images have confirmed the effectiveness of Neyman-Pearson detectors based on locally weighted sample mean and variance. In line with Bayesian approach the threshold parameter is defined as a function of prior distribution. According to the basic idea of Gibbs Sampler the neighbourhood system of image element determines the distribution of this element. Using the concepts described and taking any image as an initial we can form sequence of images in order to develop this dependence. As a result the quality of object detection can be improved significantly
