Imaging air quality evaluation based on Noise Brightness Ratio & Gompertz Type Diffusion Process
2010 Edition, Volume 5, October 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A novel air quality evaluation method, which only uses the surveillance image data, is presented in this paper. Since the intensity change of the Image Quality (IQ) can reflect the photography condition change of a CCD camera, the image can be used...

Haze Removal Algorithm for Optical Remote Sensing Image Based on Multi-Scale Model and Histogram Characteristic
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Optical imaging remote sensing technology is an important technical means to obtain information of ground objects, but it is restricted by bad weather such as clouds, rain and haze. In haze weather condition, optical images often have poor contrast and blurred details, which has a...

Histogram equalization-based techniques for contrast enhancement of MRI brain Glioma tumor images: Comparative study
2018 Edition, March 1, 2018 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In Magnetic Resonance Imaging (MRI), the poor images quality, particularly the artifacts inherent to this type of images as well as the low contrast between tissues and inter-individual variability, could make difficult the image analysis and affect the...

Performance analysis of filtering techniques for speckle reduction on breast ultrasound images
2016 Edition, September 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Breast cancer is one of the most frequent types of cancer occurs in women and also the leading cause of women's death in the world. Ultrasonography (USG) is the common modality which is used as the diagnosis tool due to its low cost and portability. It is used to early detect breast cancer....

Improving quality of medical ultrasound images by filtering of frames sequences
2011 Edition, November 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The lesion detectability by using ultrasound images is reduced by a factor of eight due to the presence of noise hampering the perception and extraction of fine details. Speckle noise occurrence is often undesirable, since it affects the tasks of human interpretation and...

Video Cameras Specification Guide
IEEE GlobalSpec

Video cameras record live-action scenes that are available for viewing via a stored or transmitted video feed. This allows the user to create a permanent and detailed chronicle of events. Original video cameras-invented in the late 19th Century-created a "motion picture." This term is still apt...

Thrust Bearings Specification Guide
IEEE GlobalSpec

Thrust bearings have rolling elements which primarily support the axial loads of rotating devices. Several styles of bearings are available in thrust configurations. Whereas radial-load bearings locate ball or roller races on the opposing inner and outer bearing rings, most thrust bearings...

MSilica Nanoparticles Treated by Cold Atmospheric-Pressure Plasmas Improve the Dielectric Performance of Organic-Inorganic Nanocomposites
Amp-Line Corp.

Microfluidic mixing using contactless dielectrophoresis The first experimental evidence of mixing enhancement in a microfluidic system using contactless dielectrophoresis (cDEP) is presented in this work. Pressure-driven flow of deionized water containing 0.5 mm beads was mixed in various chamber...
