Texture image analysis is one of the most important working realms of image processing in medical sciences and industry. Up to present, different approaches have been proposed for segmentation of texture images. In this paper, we offered unsupervised texture image segmentation based on Markov Random Field (MRF) model. First, we used Gabor filter with different parameters’ (frequency, orientatio...

The studies of texture perception focused mainly on displaying the textures with interior space gap in the millimeter level and below. We could call this kind of texture “fine texture”. In contrast, the “macro texture” has space gap in centimeters and above, and it is considered as the special texture with tiny texture pattern covered on curved surface. Macro texture contains richer surface inf...

Texture is one of the important features used in CBIR systems. The methods of characterizing texture fall into two major categories: Statistical and Structural. An experimental comparison of a number of different texture features for content-based image retrieval is presented in this paper. The primary goal is to determine which texture feature or combination of texture features is most efficie...

Image quilting is a texture synthesis technique to create a large texture by wrapping around patches of a small texture in a way that the repetition of small texture is not noticeable. The basic algorithm is to randomly select small patches in a given texture. These patches are then positioned in a large texture to be synthesized and blended across boundaries to remove the appearance of boundar...

We assessed the frequency and causes of neurological deterioration in 59 patients with spinal cord injury on whom reports were prepared for clinical negligence litigation. In those who deteriorated neurologically we assessed the causes of the change in neurology and whether that neurological deterioration was potentially preventable. In all 27 patients (46%) changed neurologically, 20 patients ...

Some researchers have compared neuropsychological performance in schizophrenia groups with and without presumed IQ decline. Inherent in this approach is an assumption that group differences are due to different IQ trajectories (stable vs. declining), but neuropsychological differences could be a function of current IQ regardless of the presence or absence of previous IQ decline. We examined thi...

BACKGROUND The report of the Ministerial Review of Trauma and Emergency Services in Victoria, Australia, recommended that paramedics be permitted to divert to the closest hospital in incidences of life threatening situations prior to and during transport. An audit of patients that suddenly deteriorated in paramedic care was recommended by the Ministerial Review. The objective of the study was t...
