BACKGROUND A well-known diagnostic imaging modality, termed ultrasound tomography, was quickly developed for the detection of very small tumors whose sizes are smaller than the wavelength of the incident pressure wave without ionizing radiation, compared to the current gold-standard X-ray mammography. Based on inverse scattering technique, ultrasound tomography uses some material properties suc...

In harsh environmental conditions characterized by unfavorable lighting and pronounced shadows, human recognition based on Short-Wave Infrared (0.9-1.7 microns) images may be advantageous. SWIR imagery (i) is more tolerant to low levels of obscurants like fog and smoke; (ii) the active illumination source can be eye-safe and (iii) the active illumination source is invisible to the human eye mak...

Cone Beam (CB) Imaging is used in maxillofacial imaging for various indications. Little is known about the patients influence on achievable image quality. In this paper we present a retrospective study, investigating the image quality of 50 CB datasets by four observers. Different views were offered and observers rated image quality on various anatomical structures in marks from 1 to 5. Scores ...

Image fusion is to reduce uncertainty and minimize redundancy in the output while maximizing relevant information from two or more images of a scene into a single composite image that is more informative and is more suitable for visual perception or processing tasks like medical imaging, remote sensing, concealed weapon detection, weather forecasting, biometrics etc. Image fusion combines regis...

background motion artifacts that degrade image quality of coronary ct angiography (ccta) in patients with high heart rates may be reduced with specific automatic motion correction algorithms (amc). conclusions ccta image quality improves significantly with amc in patients with high heart rates and reduces the proportion of non-diagnostic examinations. results mean heart rate during ccta was 61 ...

backgroundit is not clearly specified that which of the components of body mass index (bmi) affect body image and which of them do not. given that having information in this regard is of special importance as a basis for future planning for adolescents, the present research aimed to compare body image in female and male adolescents and study its relationship with body mass index in high school ...

body image is an internal representation of the external appearance which includes physical and perceptual aspects and attitudes toward them. body image anxiety can cause weight problems. in addition, perfectionism, the trend or effort to be perfect and flawless can cause extreme thinking and self-criticism. perfectionism can provoke anxiety and concerns for body image and weight, especially in...

We investigate the performance of state of the art universal steganalyzers proposed in the literature. These universal steganalyzers are tested against a number of well-known steganographic embedding techniques that operate in both the spatial and transform domains. Our experiments are performed using a large data set of JPEG images obtained by randomly crawling a set of publicly available webs...

BACKGROUND Our objective was to examine the effect of antenatal peer support on rates of breastfeeding initiation. METHODS We performed a systematic review of randomized controlled trials, quasi-randomized trials and cohort studies with concurrent controls. We searched the Cochrane Library, MEDLINE, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), the National Research R...

Digital images contain a lot of redundancies, therefore, compression techniques are applied to reduce the image size without loss reasonable quality. Same become more prominent in case videos which contains sequences and higher ratios achieved low throughput networks. Assessment quality such scenarios has particular interest. Subjective evaluation most is infeasible so objective preferred. Amon...
