I. INTRODUCTION
In recent years, the digital image collection has been rapidly increasing the size of the image. Every day, the gigabytes of images generate in military and civilian equipment. A huge, information is out there. To use this available information effectively, efficient methods for storage, browsing, indexing and retrieval. Since the 1970s, image retrieval has been an active research area within two major research communities: database management and computer vision. These research communities study image retrieval from two different angles. The first is primarily text based, whereas the second relies on the visual properties of the data. The size of image database is very better than the two problems render manual annotation

The Malignant tumor grows and spreads quickly everywhere in the nearby areas. Benign tumors are slow growing and do not spread in their neighboring tissues. Medical images are digitally represented in a multitude of formats depending on the modality, anatomy, and scanning technique. The most outstanding feature of medical image is always displayed in gray scale or color images. MRI is the most commonly used technique for monitoring and evaluating the brain tumors. Sequences of images in MRI called slices, are obtained from any of the three orientations. The three orientations of the human brain are axial (neck to the head), sagittal (ear to ear) and coronal (front to back). Proton density (PD), Longitudinal relaxation time (T1) and transverse relaxation time (T2) are the three types of images produced by MRI. Computed tomography (CT), single photon emission computed tomography (SPECT) and positron emission tomography (PET) are the other imaging techniques also available. CT provides the hard tissues like bones and MRI is used only in the soft tissues of the imaging organ, but is more efficient than CT because of its contrast
The lecture was focused on the head trauma outcome and how could the trauma information be improved using advanced MRI techniques. A TBI typically stands for Traumatic Brain Injury. . A closed injury could affect the cognitive, emotional/Behavioral/Psychological, Physical/Somatic part of the brain. Its symptoms may suggest TBI, Pituitary Deficiency, Binocular Visual Dysfunction. Nowadays, mild TBI (mTBI) prevalence is increasing rapidly.
Valuable diagnostic information can be obtained from the ability to view bone surfaces. For example, Blankstein observes that fractures can be seen as disruptions in the cortex. Many types of pathology can be identified as cortical irregularities including Hill-Sachs disease, osteolytic lesions, exostoses, and osteophytes. Bone tumors have been evaluated with ultrasound. Ultrasound is particularly advantageous in this case because blood flow to the tumor can be assessed in the same exam using Doppler settings.
Positron emission tomography or pet, it is an advanced tomographic functional imaging modality. This technique depends on detecting gamma ray produced by radio tracer like 18 F "FDG" flouro deoxyglucose through pair production resulting in a pair of gamma-ray each with 511 Kev energy an 180° "add picture of annihilation event ". The uptake mechanism of FDG depends on the metabolism rate of the cell whether it was organ, muscle or a tumour cell. Using this modality technique can help us to accurately diagnose and evaluate re-evaluate patient after
S.S. has average vision. S.S.’s vision was evaluated using picture matching. Because S.S. could not verbally respond to what she was able to see, she would match pictures held near her to corresponding images at the back of the room. During the evaluation S.S. was also able to correctly select picture symbols when asked, demonstrating her ability to accurately see picture symbols while using a SGD. f.
The experiments conducted, demonstrate the use and effectiveness of association rule mining in image
I. Type of cancer and Its Effect on Cell Growth: Head and neck cancer includes cancers of the mouth, nose, sinuses, salivary glands, throat, and lymph nodes in the neck. Most begin in the moist tissues that line the mouth, nose and throat. II Possible causes and prevention: Tobacco products play a significant role in about 80 per cent of cases. Researches indicate Eighty-five percent (85%) of head and neck cancers are linked to tobacco use.
Everyday we encounter new and familiar faces. We are able to distinguish our mother’s face from a stranger’s face due to the facial recognition processes that we have stored in our brains. Facial recognition is one of the many processes of object-recognition. Many of us are not aware of the brain’s role in facial recognition because it is a process that we are not consciously doing. Face recognition differs from object recognition in a few ways.
The differing view points include counterarguments and restrictions explored through the use of reasoning and analysis. The two intentions of neuroimaging proposed by Calheart include; localizing cognitive processes in terms of anatomical regions and the opportunity to test cognitive theories through neuroimaging. The deficiency in the fMRI’s fundamental abilities is what Calheart basis his argument on. Calheart suggests that localization studies do not inform cognitive theory.
These are only some of the reasons why a tumor in the brain is so complicated. Brain tumor is classified based on the origination of tumor cells, and whether they are malignant (cancerous) or benign (non-cancerous). While benign tumors are the least aggressive, has clear borders and originates from cells within or surrounding the brain that do not spread into other tissue; malignant tumors do not have clear borders and contain cancer cells that grow rapidly and invade surrounding brain tissue. Primary & Secondary Brain Tumors Primary Brain Tumor:
Abstract— Face recognition is one of the most important biometric and face image is a biometrics physical feature use to identify people. Major and Minor segments of face space are eyes, nose and mouth. In biometrics quality face is the most imperative characteristic method for recognize individuals. High intra-class variety inside face pictures of the same individual is the significant issue in face distinguishment. Posture, statement and enlightenment are in charge of high intra-class variety.
Some advantages of this technique are that there is no radiation involved, it is good at visualizing soft tissue, and that since it can visualize soft tissue so easily it can identify a multitude of different problems. Some disadvantages are that it is time consuming, expensive, and there is extensive training needed to operate it. The last type of imaging technique that will be covered is conventional radiography which can detect foreign bodies and changes or lesions of the skeletal system and is used when the corpse cannot fit into the CT machine. The advantages of this technique are that it is simple, quick, and cost efficient. However, it uses radiation, cannot make three-dimensional reconstructions, has a superimposed image, and it cannot visualize soft tissue
In medical techniques, the orientation of certain planes must be specified to depict the interests section. Three basic planes identify the position within the body. Figure (2.3) gives a diagram of planes through the human body. The sagittal (or median) plane is parallel to the body axis and it divides the body or an organ into right and left sides. The coronal (or frontal) plane divides the body into anterior (front) and posterior (back) portions.
Has people's use of Photoshop gone too far? Is altering photos to make people unrealistically skinny a good idea? For years, many photos in magazines, advertisements, etc. have been altered, making models and celebrities blemish free and thin. But in some cases of retouched photos the outcome can be horrific, making the person very unprofessional and disturbing. But making models thinner than they actually are can have bad effects on the public.
In second language learning, using visual aids is a necessity teaching strategy in both English as Second Language (ESL) classroom and English as Foreign Language (EFL) classroom (Allen, Kate & Marquez, 2011). They believed that using visual aids in the process of teaching a foreign language can strengthen what learners have learned and increase their interest. In their article, they proposed the positive impact of using visuals and they concluded that teachers should become aware of the strategies in which they can use visual aids and use them purposefully in the classroom to enhance students’ learning. Visual aids can be defined as using objects, drawings, charts, photographs, videos, multimedia presentation, etc.
