i ntroduction: we studied and measured facial parameters of 160 students,aged 22-24 years attended at sahand university of technology in northwest of iran. mat erial and methods: in this paper, six linear and six angular facial parameters are measured. these parameters are measured in frontal and profile facial images. the measured values are the mean and standard deviation (sd) of distance bet...

Surface roughness measurement is widely used to estimate the quality of the product during manufacturing processes. It has a great importance in manufacturing fields such as ceramic tiles, glass, and iron. Many are using surface profile-meter with a contact stylus to measure the surface roughness of work piece. In the stylus method, a stylus is moved along the surface and the vertical movement ...

This paper presents a novel method for diffusion MRI registration that treats diffusion profile as an arbitrary positivevalued function of spatial direction and treats Cartesian diffusion tensors as a special case. A metric based on elementary notions of signal analysis is presented and in the case of diffusion tensors, a closed form expression of the metric is derived in terms of tensor compon...

Chromosome image analysis is composed of image preparation, image analysis, and image diagnosis. General procedure of chromosome image analysis includes of image preprocessing in the first step, image segmentation, feature extraction, and image classification in the last step. This paper presents the preliminary results that use probabilistic neural network to classify chromosome image into 24 ...

background: mammography is the primary imaging technique for detection and diagnosis of breast cancer; however, the contrast of a mammogram image is often poor, especially for dense and glandular tissues. in these cases the radiologist may miss some diagnostically important microcalcifications. in order to improve diagnosis of cancer correctly, image enhancement technology is often used to enha...

Single image super resolution is a classic and active image processing problem, which aims to generate high resolution (HR) image from a low-resolution input image. Due to the severely under-determined nature of this problem, an effective image prior is necessary to make the problem solvable, and to improve the quality of generated images. In this paper, we proposed a novel image super resoluti...

An important factor in material quality is the time duration that materials are used (known as substance lifetime). Lifetime is a function of several factors, and among them wearing and abrasion resistances are more important than the other aspects. In addition, to the physical and mechanical properties, abrasion has a significant effect on the textiles appearance. This phenomenon considerably ...
