In one-shot color structured light systems, the color of stripe patterns are typically distorted with respect to color crosstalk, ambient light and the albedo of the scanned objects, leading to mismatch in the correspondence of color stripes between the projected and captured images. In this paper, an adaptive color calibration and Discrete Trend Transform algorithm are presented to achieve hig...

Abdul Qadir Jurjânî, with his two famous books, is the most important scholar of Islamic rhetoric. He is the founder of rhetoric in the Muslim world. One of Jurjânî’s most prominent accomplishments is his comprehensive classification of metaphors. First of all, Jurjânî distinguishes between non-expressive and expressive metaphors, and then presents subclasses for expressive, or “useful”, metaph...

Human head pose and gaze directions have traditionally been studied for expression and face recognition, and human computer interaction [6]. Accurate estimations of either head or gaze direction can provide useful information for the inference of a person’s intent and behaviour. However, most existing techniques rely upon medium to high resolution images captured under well controlled condition...

Mapping landslides and building landslides inventory have received a special attention from a wide range of specialist. In building a landslide inventory an important step is the spatial delineation of the landslides body, followed by the landslides classification according with an international used classification system and the identification of other landslides characteristics. The main meth...

Introduction:It is well-recognized that collimator-detector response (CDR) is the main image blurring factor in SPECT.  In this research, we compensated the images for CDR in molecular SPECT by using STIR reconstruction framework. Methods: To assess resolution recovery capability of the STIR, a phantom containing five point sources along with a micro Derenzo p...

to date, a number of numerical methods, including the popular finite-difference time domain (fdtd) technique, have been proposed to simulate ground-penetrating radar (gpr) responses. despite having a number of advantages, the finite-difference method also has pitfalls such as being very time consuming in simulating the most common case of media with high dielectric permittivity, causing the for...

Background: Accurate and early detection of non-alcoholic fatty liver, which is a major cause of chronic diseases is very important and is vital to prevent the complications associated with this disease. Ultrasound of the liver is the most common and widely performed method of diagnosing fatty liver. However, due to the low quality of ultrasound images, the need for an automatic and intelligent...
