چکیده

The text deals with the problem of detecting anomalies on a background of multi-dimensional images. We synthesized a detection algorithm based on the use of doubly stochastic models of random fields and which requires pre-filtering the image. We propose to use the modified Kalman filter. We also investigated an efficiency of extended signals detection on real images. It is shown that the resulting algorithm has a higher efficiency than the known algorithms which based on the traditional autoregressive image description. The gain is explained by more adequate description of the real inhomogeneous material using doubly stochastic models.

Separation Between Anomalous Targets and Background Based on the Decomposition of Reduced Dimension Hyperspectral Image

The application of anomaly detection has been given a special place among the different   processings of hyperspectral images. Nowadays, many of the methods only use background information to detect between anomaly pixels and background. Due to noise and the presence of anomaly pixels in the background, the assumption of the specific statistical distribution of the background, as well as the co...

Standard edge detection algorithms versus conventional auto-contouring used for a three-dimensional rigid CT-CT matching

Background: To reduce uncertainties of patient positioning, the Computerized Tomography (CT) images acquired at the treatment planning time can be compared with those images obtained during radiation dose delivery. This can be followed during dose delivery procedure as Image Guided radiotherapy (IGRT) to verify the prescribed radiation dose delivery to the target as well as to monitor ...

DETCIC: Detection of Elongated Touching Cells with Inhomogeneous Illumination using a Stack of Conditional Random Fields

Automated detection of touching cells in images with inhomogeneous illumination is a challenging problem. A detection framework using a stack of two conditional random fields is proposed to detect touching elongated cells in scanning electron microscopy images with inhomogeneous illumination. The first conditional random field employs shading information to segment the cells where the effect of...

Parameter Estimation for Inhomogeneous Markov Random Fields Using PseudoLikelihood

We describe an algorithm for locally-adaptive parameter estimation of spatially inhomogeneous Markov random elds (MRFs). In particular, we establish that there is a unique solution which maximizes the local pseudo-likelihood in the inhomogeneous MRF model. Subsequently we demonstrate how Besag's iterative conditional mode (ICM) procedure can be generalized from homogeneous MRFs to inhomogeneous...

An anisotropic diffusion-based defect detection for sputtered surfaces with inhomogeneous textures

Texture analysis techniques are being increasingly used for surface inspection, in which small defects that appear as local anomalies in textured surfaces must be detected. Traditional surface inspection methods mainly focus on homogeneous textures that contain periodical, repetitive patterns. In this paper, we study defect detection in sputtered glass substrates that involve inhomogeneous text...
