  Citation × Citation Citation Abstract Copy Title: New Objective Classification System for Nuclear Opacification Author: Duncan, Donald D., Shukla, O. B., West, Sheila, Schein, Oliver D. Year: 1997 We have developed an autonomous objective classification scheme for degree of nuclear opacification. The algorithm was developed by using a series of color 35-mm slides acquired with a Topcon photo slit-lamp microscope and use of standard camera settings. The photographs were digitized, and first, and second-order gray-level statistics were extracted from within circular regions of the nucleus. Classifications of severity were performed by using these features as input to a neural network. Training versus classification performance was tested by using photographs of different eyes, and test/retest classification reproducibility was evaluated by using paired photographs of the same eyes. We demonstrate good performance of the classifier against subjective assessments rendered by the Wilmer grading system [Invest. Ophthalmol. Visual Sci. 29, 73 (1988)] and markedly better test/retest reproducibility. Title: New Objective Classification System for Nuclear Opacification Author: Duncan, Donald D., Shukla, O.

  Citation × Citation Citation Abstract Copy Title: Listening to Lasers: Photoacoustic Gas Sensing Author: Hopkins, Michael Year: 2016 Herein lies the makings of a sensor for gaseous materials due to the technique known as photo-acoustic spectroscopy. Whereby a gas filled metallic tube of known resonance has an impingement to its open aspect a beam of photons of known colour and at a specified rate such that the rate of incoming light corpuscles matches the natural standing wave frequency for the column of gas within said tube, to wit resonance. Through foresight of the molecular orbital theory and historic datums on the subject of infrared spectroscopy one naturally comes to the employment of absorbance transfiguring energy to kinetic motions within a known gas species as a mechanism for spectroscopic analysis. Many fortnights gone by a device of these humours was constructed and found not wanting in capability, this device shall henceforth be described in placard shewing and by the telling of its constructor.

A uniform CdSe shell layer with a grain size of approximately several tens of nanometers was formed on the surface of ZnO nanoneedle cores after annealing at 400°C for 1.5 h. Fabricated solar cells based on these nanostructures exhibited a high short-circuit current density of about 10.5 mA/cm2 and an overall power conversion efficiency of 1.07% with solar illumination of 100 mW/cm2. Incident photo-to-current conversion efficiencies higher than 75% were also obtained.

  Citation × Citation Citation Abstract Copy Title: Detecting Rule of Balance in Photography Author: Mai, Uyen T., Liu, Feng Year: 2014 Rule of Balance is one of the most important composition rules in photography, which can be used as a standard for photo quality assessment. The rule of balance states that images with evenly distributed visual elements are visually pleasing and thus are highly aesthetic. This work presents a method to automatically classify balanced and unbalanced images. Detecting the rule of balance requires a robust technique to locate and analyze important objects and visual elements, which involves understanding of the image content. Since semantic understanding is currently beyond the state of the art in computer vision, we employ the saliency maps as an alternative. We design a range of features according to the definition and effects of the rule of balance. Our experiments with a variety of machine learning techniques ([8-11]) and saliency analysis methods ([2-6]) demonstrate an encouraging performance in detecting vertical and horizontal balanced images. For future works, the balance detecting system can be developed into a subroutine for an automatic evaluation of professional photography.

The quantitative data included photo documentation of all buildings and lots (e.g. parking lots or vacant lots) within the study areas. Other empirical data collected included the address(es) of the buildings, the number of stories and/or mailboxes, land use categories such as commercial or residential (including exclusive as well as mixed use categories), the name and type of business, and the spatial coordinates of the building (latitude/longitude). This data was collected in order to provide an objective "picture" of the neighborhood at a given point in time and assess the ability to map and analyze this micro-level data using GIS (geographic information systems).
