Clareamento dentário x autoestima x autoimagem

Dental changes that compromise facial harmony can have serious consequences on the social image of the patient. Depending on the emotional significance for the individual it can change interpersonal relationships, causing profound changes in their patterns of self-acceptance and self-image, with profound effects on their self-esteem of the patient. The search for tooth whitening as cosmetic factor for a harmonic smile grew sharply in the last decade. Although the color of the tooth represents only one aspect in the set of determinants of facial harmony, it is a strong factor because it is quickly perceived. This study aims to report the clinical case of a patient with spots on their upper central incisors. For the patient these spots have compromised her smile, causing harm and discomfort in their everyday social and professional relationships.

Estimation of crowd density using image processing

Human beings perceive images through their properties, like colour, shape, size, and texture. Texture is a fertile source of information about the physical environment. Images of low density crowds tend to present coarse textures, while images of dense crowds tend to present fine textures. This paper describes a new technique for automatic estimation of crowd density, which is a part of the problem of automatic crowd monitoring, using texture information based on grey-level transition probabilities on digitised images. Crowd density feature vectors are extracted from such images and used by a self organising neural network which is responsible for the crowd density estimation. Results obtained respectively to the estimation of the number of people in a specific area of Liverpool Street Railway Station in London (UK) are presented.
