Image sensor

Medical image analysis plays a vital role in medical diagnosis is a broad area of education and research attention. Medical imaging techniques become a nature look with different characteristics depend upon the selection of modalities with the requirements ( Li Luo 2007). For example, CT offer supreme information on denser tissue with smaller amount distortion whereas Magnetic Resonance Image (MRI) offer superior information on soft tissue with supplementary distortion (Yong Yang et.al. 2010)…

It is an examination, which is only based on the “assumption” that there is an interaction between the mind and body and is conducted by various components or the sensors of polygraph machine, which are attached to the body of the accused, who is interrogated by the expert. The machine records the blood pressure, pulse rate & respiration & muscle movements. Polygraph test is conducted in three phases (a) pre-test interview, (b) chart recording (c) Diagnosis. The examiner will prepare…

In today’s world, one of the greatest challenges being faced by individuals across a vast array of disciplines is protection and security. If we are to take a moment and reflect upon every instance during our everyday lives in which we use some sort of technology to access personal information or encounter something in which we are required to prove our identity, we can clearly see that there are numerous opportunities through the day in which our information is at risk. Therefore, it becomes…

one pixel is captured, however in a plenoptic camera there is the camera lens, the microlens array and an image sensor. In order to work, the microlens array is placed in the focal plane of the camera main lens and the image sensor is put in the microlens array focal plane, so when the light passes through the array, it reaches many pixels. This way it is possible to obtain depth and the image can be digitally refocused after it was taken. (Trujillo-Sevilla, J. et al.…

The RoboBEER incorporates an iPhone 5S camera (Apple Inc., Cupertino, CA. USA) to record videos for further image analysis with a customised Matlab® code which is capable of calculating parameters such as the maximum volume (MaxVol), life time of foam (LTF) and total life time of foam (TLTF), and three sensors to measure alcohol gas content, temperature and release of CO2 within the period of video capturing. In this paper, the functionality of RoboBEER is…

change lenses and are equipped with digital sensors. You can capture and record your photos and videos onto memory cards and hard drives. SLR: This camera uses an electronic viewfinder and captures pictures on…

A number of phone companies have started to add fingerprint scanners to their phones. “Just like smartphone cameras, these sensors can have a finite resolution, and the higher the resolution, the finer details the sensor can discern about your finger, increasing the level of security.”2 The most popular devices that have added reliable fingerprint scanners are Iphone, and the Samsung Galaxy S models. With the fingerprint…

electronic devices that quantifies and measures changes in the given environment. Fire Alarm devices, such as fire detectors, have sensors that detect fire/flame and send a signal to a sound device that produces an alarm or switch on an image recording device. There are fire detectors which employ cameras connected to a computer which stores and manages captured images to be viewed over a computer network. 1.2 Problem Statement The death rates due to fire are very high and increasing day by…

greatest medical advancement in the last decade, digital radiography (DR) would certainly make the list. This method allows the production of x-ray images without the need for a radiographic cassette and film. Instead, the imaging sensor is attached to a DR computer via a cable wire or is permanently fixed to an x-ray table. This allows for the immediate image capture of an x-ray on a monitor. But as with every advanced piece of technology, there are certain advantages and disadvantages to…

Introduction Urban sprawl is the expansion of a city or its suburbs, especially the commercialization in rural areas including farmland or undeveloped lands, such as forests and open spaces. Urban sprawl can be caused by numerous factors including rapid population growth, rise of living standard, decrease of land rate, lack of urban planning, etc. Urban sprawl creates numerous problems that would decrease in environmental quality through wildlife habitat destruction, deforestation, wetlands, and…
